Hdpe Pipes and Fittings


HDPE Pipes, Polyethylene (PE Pipe) are sorted by strength classified according to the intensity of the earlier technological developments. HDPE Pipe pressure classes that can be made between Pn4-Pn32 and the production of the desired diameter and size of HDPE pipes system has undergone many tests in 1950, particularly in the carriage of drinking water. After the result of these tests of HDPE Pipes, if all reports are positive then it has no harmful effect on human life. One of today’s most widely used pipe is HDPE pipes systems which is  economical, easy in handling, efficient  performance, easy method of coupling. Is quite useful and is produced by KUZEYBORU.


Polyethylene 100 Pipes for stability (creep) pressure account;


Polyethylene Pipe, Pe 32 class is developed in 1950 with improving technology  and low density. 3rd Generation PE 100 Polyethylene raw materials  are used in drinking water pipelines, desalination plants, biological treatment plants, swimming pool piping, sea discharge lines, gravity flow water lines, gas stations , irrigation lines, compressed air lines, cooling-heating lines, pre-insulated sheathing for pipes. Because Low Density Polyethylene Pipe is economical and has high-performance in many areas, such as sewer lines has been a solution. (C2H4) has the general formula of crude oil of 97% polyethylene and is a thermoplastic polymer as shown. The production of raw materials, entirely depends on the availability and price of crude oil. Polyethylene density  is divided into three main groups according to their crystalline structure percent.
• Low density polyethylene raw material (LDPE)
• Medium density polyethylene raw materials (MDPE)
• High density polyethylene raw materials (HDPE)

According to other types of raw materials as well as their field of high performance and long life due to the strength of economy most preferably 97% of the product which is used crude for the production of the polyethylene raw material. So the production of polyethylene raw materials, the availability and the price depends entirely on crude oil. It also has many superior properties compared to other thermoplastic polyethylene. The main ones are
HDPE Pipe is resistant to weather conditions

* HDPE Pipe is suitable for radioactive waste.

Bimodal Polyethylene / PIPE

Polyethylene for pipes with advancing technology began to be produced on 1950 II. Polyethylene generation until 1970 and in the 1990s began to be used in the biomedal period polyethylene was formed. Polyethylene should demonstrate excellence in strength and workability is provided by the bimodal polyethylene to accommodate these features  Bimodal Polyethylene known titles can add a few more outstanding features. These are:
* Resistance against cracking tube is perfect.
* It is spacious and provides a cross-section.
* Increases the volume of flow of fluid to pass through the pipe.
* Deflection making tendencies are low

Ultraviolet (Sunshine) Resistance

In the absence of any physical and chemical protection from UV radiation is affected polyethylene and weakens. Thanks to between 2-3% of carbon black incorporated into the UV input during the production of the weakening cut is avoided.

Classification of Polyethylene Pipe

MRS; Polyethylene pipes and classified by the raw materials used in the production of attachments. MRS material strength values of 20 ° C is also shown by the internal pressure for 50 years.

HDPE Pipes are the external factors that affect their lives;

* HDPE Pipes ( Polyethylene pipes) working conditions in, temperature, pressure and fluid properties.
* HDPE Pipe is produced from chemical reactions of rawmaterials.
* Soil structure used during the pipe-laying for PEHD pipes that suits to conditions.

2- Feild Assembly

2.1- Polyether Storage and Transport 2.2.1- Storage

After the production of HDPE pipe, there are some important points to be considered while the storage structures. * Accumulation against the proposed measures should be taken and must be 1 meter in height. * Coils are silos for the proposed arrangement. Silo is important not to disturb the balance in the individual coils received. * Straight pipes should be arranged in horizontal rows and so it should stand from the bottom row to the top row angle. The shift of pipe supports should be avoided as well.

Of storage on top of the pipe:

• Pipes must be stored in a remote way of sharp objects in a horizontal plane. • PE Pipe fittings in a closed manner, should be stored in the package. • PE pipe and fittings waste water, dirt and soil contact must be avoided.

Transportation or shifting:

* Freezing or maintained at a lower temperature than PE pipes are becoming weak against shocks. Therefore pipes should not be reduced quickly by dragging on the ground, it’s impact should be seen. * Polyethylene Pipes with the handsaw when cutting and freezing bilateral assistance should be provided if done at a lower temperature may break or bend. * Polyethylene pipe will be carried during the transport of the vehicle must be full length of the pipe in the pipe tools and should be hanged out. * After the move is finished Polyethylene pipe absolutely must use ropes or chains when they are shifted down from the transport vehicle. pipe and fittings must not be thrown to the ground. Use forklifts or cranes use the recommended shifting method.

2.2- Sliding Support Renovation

2.2.1- The open (air) hinged flor

Intervals are restrained; laying line, the temperatures existing in the environment, size and characteristics of the pipe depends on the fluid properties. Usually need continuous support for small-scale Although intermittent bearings used. Saddle bracket, the bottom of the tube 120 degrees (minimum) should be up bed. To prevent the bearing from damaging edge of the pipe must be taken to be pointed. Supports formula used to calculate the range are as follows; L = [(3840xExlxd / (5(Wp+Wf))1/4] / 100 Details; L: Support Range (m) E: Young’s modulus (MPa) l: the inertia of the pipe (cm4) d: Permitted collapse (cm) Wp: Pipe unit weight (kg / cm) WF: The unit weight of the fluid (kg / cm) EUR table of typical values PE 100 pipes for long periods of use

2.2.2 Burying Ground Floor

Soil pipe laying in the classic sense to dig, lay, off, requiring a very different and meticulous engineering of logic is a serious work. Terms and explanations that we give here will be the guidance that will enable us to have information on the matter. Making process of laying buried in the soil as it requires decisions should be made and given to the different application methods.
Materials and Processes on the pipe burial

Fitted foundation:

When you are finished digging needs to be done with enough strength on the ground if not the strengh should be made enough.

The layer/ground:

Ditch the ground state according to the required form to implement the process according to the flat level.

Primary and secondary fillers :

The height of the pipe from the ground Trench landfill is made to increase at least 15 cm. The fill tube that improves the quality and lifetime durability.

Primary Filler:

The quality of the material and application technique used in this section is very important. The diameter of the pipe rising from the bottom of the filler pipe is raised to 75%.

Secondary filler:

It is fuller of the distribution of load on top of the reason for making and maintaining the pipes against the play that may occur after the end filler. Place in case of rising to the level of underground water pipes and come in second if the first is filling more.

Last filler:

Although there is not too much of an effect on the structure of the HDPE pipe and pressed. To ride a solid filler pipe will reduce the upper end loads.
Last filler material and the compression paths, sidewalks, etc. structure/processing rules must be observed.

Installation Guidelines for PE Pipes

Workplace and the work to be done by engineers to consider the shape of the surface and it is difficult to determine that which part needs the reinforcement of the pipe. Specific guidelines for situations such as low soil depth is more than the thickness of the meat should be prepared. In general, it is sufficient that we understand the methods for general application. These applications are not installed to deep, on overload events, and are conditions that are sufficiently resistant to pressurize pipes.

Simplified Application Methods for HDPE Piping

Most of the time an application is required for successful implementation of the following conditions successfully. steps occured by providing the following conditions;
1. The pipe diameter of 600 mm or less
2. SDR 26 or less
3. Fill size of between 0.75 m to 5 m
4- be at least 60 cm from the surface of the groundwater.

Simplified Installation Stages


Trench work is a risky method for employees trench collapse are likely to be in every land. That’s why workers’ health and life-threatening measures should be taken consideration. Trench edges must be kept at a safe angle. According to the recommended length trench laying pipe diameter and depth are included in our table below.


After you have created volatility in the ground floor of the ditch it should be evenly filled with the ground bearing. If the bottom of the ditch, filling up to a height of 10-15 cm over rocky bottom. Filler material will be sand, gravel must be non-adherent sand or gravel mixed. Channel depth should be at least 70-80 cm and materials to be made into filler sand or gravel should be non-adherent sand mixed gravel. There’s no need to interfere if the grounding has been done by landfill. Otherwise, the sand and so on should be utilized. Fillers should be adapted to make up the beds. *Things to bear thickness must be a minimum of A1 = 100 mm + DN 1/10. * Pipe filling A2 side, with light pouring in 30 cm thick compact yet 92% – must be compressed 95 percent. This process should be continued via a tube every 30 cm for 30 cm. The layout of pipes in the Channel

Protection from water:

Convenient and safe water level in a ditch must be made below the mouth of the tube. Water is necessary not to enter the pipe. The high water level should help dig wells or draw pump.

To tile curved pipe:

Flanges and fittings for connection to the pipe is rigid both before and after. The distance to the pipe diameter should be 5 to 100 times of bending radius. Once settled into the ditch pipe may require the use of arch supports to protect. These supports must be removed without support after the last filling placed.

Placing pipe trench:

200 mm in diameter and 9 kg / m is possible to lay the pipes weighing up manually, but for heavier pipe is certainly a need for suitable transport vehicles and equipment.  During insertion of tube pipe it should be taken into consideration that no one is around in order to minimize the danger. After the sun set in the heats expanded pipe into the trench it should then be allowed to cool and mechanical connections are provided.

Primary filler:

The primary materials used in the filling of pipes in place should be put into place so as not to play and must be tightened. During this process it is fully seated and replace the pipe should be checked to enclose the filling pipes . This process is essential for using percussion and vibratory plate compactors.

From a different material than HDPE pipe fitting gasket transition:

When pressurized HDPE pipe remains under two different internal forces. 1. Gives cause environmental stress. 2. Twist and thrust tube are reflected as axial tensile stress at the end of the pipe. Axial tension to extend the neck of the tube to expand the diameter of environmental stresses, which may occur, this is the Poisson ratio when the process attempts to shorten the length. In HDPE pipe system keeps itself Briefly, and you do not need to take any measures against the push.

Embedding HDPE Fittings:

HDPE pipes and fittings do not need an extra push against the mounting pressure of being the only part of the reason. Then if the connection to muffle against the fixing process must be made to leave.  In HDPE pipe elastic deformation will occur in situations such as thermal expansion valve, etc., but will not damage the movement caused by the movement of the parts to add an undue burden on the pipe. Here, a sealant made of suitable process reveals the quality of the filling process to the circuit that prevents excessive load.  TA distinctions, the same filler pipe fittings for masts and other general sufficient. A special material made of PE compression process for service connections can not be realized.  T is a need for consolidation and elbow of sand and cement. recent fill the excavated material can be used in the materials, but unsuitable material in order for it must be extracted. This filler pipe assembly operations should be carried out immediately after the end. Thus, the possible impact of the pipe will be protected from cold weather conditions over the case and hook up.

2.2.3- Water Under Floor

Most convenient and most widely used material in the pipe-laying process which will be held under water is HDPE pipe. The main reason, and other advantages are described below.
HDPE pipe is light; One of the most important characteristics of lightness is the HDPE pipes. According to the steel pipes 50%, slightly more than 10% of the concrete pipe. Shipping and handling is easy.
HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water combined. And when it comes to places to be taken down by placing weights on the settling of pipes supplied.
HDPE pipe is flexible; To adapt to the bottom surface of the immersion pipe and living possible.
HDPE pipe is soft; HDPE pipes and discharge that may occur in water due to the high deformability, can resist against the waves. It ensures the consistency of the tube against the bottom surface changes due to the same reasons. HDPE pipes are inserted tubes to length to each other. The place is as strong as welded pipe. There is no risk of leakage. HDPE 100 pipe may face even as it filled with water. Therefore weight should be added while floating on a platform or on land.  Swimming process piping can be moved to the desired location and the dipping process is carried out at  appropriate place.  It can swim with the air inside the pipe is full of water must be able to sink the recharged by weight. If this is achieved the control of water pipe breaks in the water filling into the pipe it will occur. If you need to excavate trenches for pipes to be buried under water it is required before the dipping treatment in this process. Will be held to fill the excavated trench should consist of crushed rock for additional protection should be placed in the rock or concrete parts.
Basic Design and Installation Stages for Underwater Applications:

1. Determining the appropriate pipe diameter:

Fluid type, based on the determination of the flow and the pipeline hydraulic calculations to be made. Tube inner diameter should be determined accordingly.

2. Assembly and the calculation of the appropriate size considering the working conditions rate:

Important in terms of temperature and pressure tube is reliable and necessary. The pressure of the pipe should be checked to meet the hammer.

3. The calculation of the required weight and installation range to Dip Tube

3.1- Buoyancy in the water a tube has the formula below;

F = [W pipe + W material] – W overflow
F= The buoyancy in the unit meter kg / m tubes
W pipe = The unit weight of pipe kg / m tubes
W material = unit weight of the substance in the tube kg / m tubes
W overflow = The unit weight of water that overflows the pipe kg / m tubes

3.2   For a complete determination of the soaked tube current weight is calculated.

Usually the overflow pipe at the bottom of the addition of a weight of between 25-50% of the amount of water is sufficient to make the precise detection. But while low enough and calm waters of the lake higher values should be used in place of draining.

3.3 should be very careful not to leave air pockets in the pipe for swimming and not to create unwanted effects and should be ensured from its condition.
3.4 and clamping range of weight must be determined to be connected to the pipe.
3.5 Making of Weight; Weights for the cause torsion during immersion usually hexagonal, square symmetrically as it is done. There is no harm in being in different ways. The tube will remain after you sink significant currents in the bottom of a flat shape and weight should be preferred. Typical weight of the weight block is located in our table below.

4- To combine water pipes and convenient choice for loading it down should be done.

Before water immersion process of the pipe should be an appropriate shore ramp and when to withdraw the floor of the pipe it must be cleaned so as not to damage the pipe surface.

5- To prepare the underwater bed upgrades, and make the controls of the transition from land to water.

Priorities should be made in the pipe in the trench until the water should be gained without stopping to provide additional protection.  To protect all kinds of mishaps that may affect the water pipe in the trench must be excavated in length and depth. So much so that the flush operation to be performed should remain robust even shark Umeda formed sea. Which will be held for pipeline protection and stabilization, 30-50 cm in height can be fortification on the filler.

6- Reflux pipe to form one unit of the pipe member

Resources made birleştirildik ends of the water pipes in front of the remaining parts will begin to creep more.

The weights should be reduced if possible above the water pipe connected to the water after the floating platform. If weight is not possible it must be done without touching the pipe water.

7. Connecting the weight block

It is required sufficient equipment and transport means for realizing the operation. The fulfillment of the weight assembly, the bottom of the lower part of the tube were removed blocks, placed on top to compress the upper part of the pipe also requires the use of this equipment and transport. To reduce the weight of the water pipe connected it should be left down the ramp. In any case the surface of the pipe to remove the least amount ramps should be as close to water as possible

8- Attached to the immersion pipe (7 could safely be performed simultaneously with the substance present in.)

Weight can be easily downloaded via the included water pipe ramp. When released into the water in the pipes of water over ramps able to hold the weight thanks to the ramp. Rope to keep the pipe materials should not be used as the chain is a method that is recommended to use wide strips instead.

9- Immersing the pipe at specified point

To prepare the first immersion tube is drawn over the line set tubing. Immersed in the process of starting the land continues to plunge into the water. To ensure that the pipe must first be lifted up to the beginning of the tube an air pocket. One of the issues to be considered in the immersion process is the completion of the folding process without the risk of excessive bending. If administered in a controlled manner to the water pipe will not be such a problem. Immersed in a situation that may occur during the supply otherwise hold back compressed air from the valve and pipe the water to swim again. However, compressed air should not be used more than 50%, the pressure of the pipe due to the water pressure is dangerous.

10. The preparation of the transition from land to water

Installation is useful in controlling the substances mentioned below with the end;
– The correct fitting pf HDPE Pipe
– The absence of weight block is regular
– Checking whether there is contact with any material that can cause damage around the pipe
– Removal of the filling of control and temporarily put in place the material certainly should be checked by experts.

2.2- Thermal Expansion

One of the difference of the expansion coefficient of the metal pipe to the metal pipe P is it is 10 times larger . That means more expansion and contraction will occur. Long-term use would be by limiting the temperature in the pressure pipe. This is usually 60 ° C t. Use of pressure for different temperatures are listed in the following table;

Thermal Expansion / Contraction Effects

Due to the change pipe and welded seams temperature stresses can easily meet. Totally it is not necessary to use a system expansion or expansion in PE.
PE 100 pipe expansion coefficient is higher than other materials need to be aware of the following;
* PE 100 Pipes that will be exposed to a certain temperature to be rejuvenated, will make snake like movements or will put pressure on the fixed point.
* Joints in the HDPE pipe connection is required to connect a methanic playing against it.

Polyethylene Pipe Joining Techniques

Melted with each other to combine the polyethylene pipe or fittings or are connected with mechanical fittings. Melted with each other to combine the polyethylene pipe or fittings are connected with mechanical fittings. Various fittings for remaining outside of polyethylene pipes, flanges or developed in accordance with the objectives of the transition adapter provided with connection.

The temperature of the media sources to do with electrofusion welding method should be between 5 ° -50 °.
The temperature of the media sources to do with electrofusion welding method should be between 5 ° -50 °.

Electro Monitoring Required Steps

Before the mouth of the pipe welding process should be checked whether their angle is with its axis. If there’s no angle then it should be discontinued and should allow for right angles to get its axis. Electrofusion sleeve pe pipe surface to be installed must be checked. Source size should in general be up to half the length of the sleeve. Marked by cutting scraping apparatus should be written so that no oxidation should be required.  After scraping is performed it should not be touched and should definitely be protected from adverse weather conditions. If deemed necessary with the clamp attached to the sleeve pipe system is fixed.  Electrofusion cables on welding machine attached to the socket on the sleeve. Barcode value is entered through the machine on the sleeve. Then the welding process is performed by giving tension to the ends of the sleeve socket. It is expected implementation of the cooling process for removing a clamp. Polyethylene pipe laying operations in the more important issue is the quality of the pipe work. Welder’s certificate and references, which will be especially important with the welding process still need to be made in the audit.

Advantages of the electro-fusion welding for PE Pipes:

It is possible to direct the output from the main pipe using the technique.
Repair of the pipe is easy.
It can be applied even in very tight spaces.
It does not require much excavation and filling.


Butt Welding; Polyethylene pipes and fittings for joining is one of the most widely used method of joining. The two ends of the pipes to be welded taken by heating under pressure is performed by pushing towards each other.
Get up to 1200 mm diameter pipes with welding assembly methods can be boiled. Butt welding bonding method is performed in accordance with DVS 2207 standards.

Quality Assurance Testing Methods

PE 100 tubing set to end at the beginning of the production and application of existing standards is mandatory. And these tests are applied. PE 100 pipes and transport of these tests can be performed only after the dispatch.

1) Thermal Stability (oxidation induction time Determination)

Antioxidant additives in time to prevent the PE material undergoing oxidation at high temperature. It is indicative of how well stabilized after the production phase of the material in conjunction with this test. In a good way to stabilizing pipe will not shorten life in a variety of reasons. We can give some information on the experiment. * The equipment is heated to 200 oC by setting after opening the cooling water and gas valves. It is put into the sample capsule and the program is executed. A distortion should not occur for at least 20 minutes since the start of the test.

2) Carbon Black Volume Analysis (ISO 6964)

PE 100 pipe of the added amount of carbon to impart resistance to UV light (%) are to be identified with. Homogeneous dispersion of the carbon content is required in the product. This does not provide a portion of the debt is affected by environmental conditions. The affected part once to suffer more than the other parts will begin to rapidly deteriorate. Part of the combustion section is combusted in a high temperature furnace with the nitrogen gas is determined as the amount of carbon and is as calculated. Let’s examine how to make the experiment; * Device 550 is heated less on gas opens until ° C. * Crucible’s tare taken are recorded and placed in a high temperature furnace put into 1 kg of samples. * Burning of the sample within 20 minutes, and burning (carbon black) portion will remain. * Put a vacuum dessicator to take moisture from the crucible environment after the implementation period. * Since end is crucible again weighed formula applying% on carbon quantity is calculated.

3) Density Test (ISO 1183)

PE is performed in order to calculate the weight of the unit volume of the tube 100. The samples are weighed in before the air then previously known liquid density. Account also has the density specified by the standard.

4) MFR (Melt Flow Rate) Test (ISO 1133)

Testing the behavior to temperature of the material to be used before it is processed with an application purpose. Results of tests performed with the device in the MFI values are loaded to the device g / 10 min. Results detected by the unit. Let’s examine how to make the experiment; • is set to 190 oC for process heating apparatus is opened. • Sample components are added to the cylinder at the top of the device. • Average length of 15 mm to flow material cut-off time is automatically entered into the device. • putting in place the first cut only 5 tracks taken part in the formula mean excluding g / min in terms of MFI has. • the material mass flow rate (MFR) g / 10 min in terms of value is calculated by the following equation: MFR (T rated) = 600 m / t T: Test temperature, ° C, Man Up: Rated load, kg m: mean mass of cut pieces, g, t: Cutting time intervals, s,

5) Tensile Strength (ISO 527)

Flow of thermoplastic pipes and profiles or max. Tensile load comprises determining the stress and elongation at break. It performed to determine the characteristics used in the manufacture of a test carried out for tensile properties and applies to all thermoplastic tubing. Let’s examine how to make the experiment; • removing such a sample from the spoon by the strips cut in parallel to the pipe axis are conditioned at 23 ° C. • compressed sample to the upper and lower jaws • Loan size is measured and recorded the conditioned samples. Furthermore, as the thickness of the sample is measured and recorded. Cross-sectional area calculated from these values. • the sample drawing speed; e≤5 mm and 100 mm / min and 12 mm ≥ A> 5 mm and 50 mm / min to> 12 mm and 25 mm / min is set. • must be greater than 350% compared to the first longitudinal elongation%.

6) Hydrostatic Pressure Test (ISO 9080 EN 921)

PE 100 pipes in the face of pressure over time was examined in order to test the behavior is tested in a shortened environmental conditions. PA 100 changes observed in the 50 year period of this test tube. Let us examine the construction of the experiment; * The device is filled with water tank and made the opening of the device (device issues to be considered must be constantly filled with water can cause this resistance to decay.) * Temperature values are encoded according to the value of the test will be made. * Water is filled into closed at each end of the sample. * With the water in the sample according to the property specified in the standard pipe is expected to conditioning * In water at 20 ° C for 100 h, 165 h in water at 80 ° C for a given pressure as described in the following formula. As a result of whether there is damage to the sample. Test pressure formula; p = 10σ x 2A / – are calculated by e. σ: environmental stress generated by the applied pressure, MPa; de: Average outside diameter of the test piece measured in mm; E: The lowest thickness of the test piece measured in the free length, mm

7) Homogeneity Test (ISO 13949)

Homogeneous pigment distribution in the structure of the material is done with the aim of examining possible gaps. Microtone taken in 10-15 m thick cross-section is examined under a microscope.
