HDPE Pipe & Fittings
High density polyethylene (often called alkathene or polythene) has been used since the early 1960s. It is suitable for both potable water and wastewater services but it can only be used for cold water supply.
It is the most commonly used plastic pipe for supplying the mains water to a dwelling. HDPE Pipes and Fitting or also known as Poly pipes are used in various Industries and application notably for plumbing and waterworks. The versatility of HDPE Pipes and Fittings are the main factor for its popularity and trust among plumbers and builders.
Some of the advantages of HDPE Pipes and Fittings are :-
- HDPE Pipes and Fittings are Durable - HDPE have corrosion resistance properties to most chemicals and corrosion. HDPE also have higher impact strength thanks to it's polyethylene resins.
- HDPE Pipes and Fittings are Flexible - HDPE are perfect for various terrain especially for Mining, Irrigation, & Sewerage applications as it provide good conformity to most terrain types.
- HDPE Pipes eliminate Water Hammer - HDPE Pipes can withstand higher transient pressure than conventional pipes as the PE Resins have greater elasticity than other types of pipes.
- HDPE Fittings have various Jointing types - There are various method to joint the HDPE Pipes and Fittings such as Push-Fit, Socket Fusion, Butt-Fusion and Electrofusion. The weld types of jointing are 100% leak free as the PE Resins are fully welded and commonly used in Higher Pressure usage while the Push-Fit type of jointing are commonly used in normal irrigation such as farm and garden.
- HDPE Fittings have Longer lifespan - Under a proper usage and installation, HDPE boast a lifespan of over 50 years.
HDPE Pipes and Fitting do not wear, rot or rust, and are a dependable and affordable material for potable-water piping, Irri. There are different types of PE Resins and the most common one is known as PE80 and PE100. There are also different type of Nominal Pressure or PN rating for HDPE Pipe and fitting ranging from PN6, PN8, PN10, PN12.5 and PN16 which suited for each Pressure rating requirement on such applications.
HDPE Pipe and Fitting Application
There are various application, services, industries and usage of HDPE pipes and Fittings.
HDPE Pipe Usage in Waterworks
The main usage for HDPE Pipe and Fitting is waterworks pipeline. The range dimension and low cost for material and installation have made HDPE piping as the suitable option for plumbers to choose HDPE piping system to be installed in both residential and commercial waterworks application.

BUTELINE PE FITTING FOR COLD WATER
Buteline has developed an extensive range of quality fittings for Polybutene-1 and Polyethylene pipes. Buteline fittings are moulded from thermoplastic and fitted with an annealed protective aluminium alloy sleeve, attached during manufacture, to provide a unique metal reinforced joint. This is where Buteline’s design stands out, the fitting design overcomes high stresses, experienced in installation and service on the tail section of the fitting, by transferring all loads applied through the pipework to the thicker body of the fitting, minimising any risk of failure. During on-site installation of the fitting, the metal sleeve ensures the correct clamping position away from the end of the pipe which maximises resistance to pull out. The Buteline Group has produced millions of these thermoplastic fittings and after many years of service, they continue to work successfully.

Standard testing for Poly pipe system :-
- A test pressure of 1.5 times the working pressure, or such lower pressure as mayb be required shall be applied to the section under test.
- The test section should then be allowed to stand without make up pressure
- At the end of the first hour, the noted pressure is allowed to drop to 1.3 times working pressure and pumped up again to 1.5 times.
- When the test pressure is attained, the pump is stopped and the rate of pressure drop is recorded. The pressure in the HDPE pipeline shall be maintained until the entire section has been inspected.
- The section is deemed to have passed the test if no leakage occurs at the weld and the average rate of pressure drop during the 2 hours period doesn not exceed 10 percent of the test pressure.
