4. Socket pipe coupling
Socket pipe coupling, it is a commonly used accessory in industrial pipe connection. A pipe coupling is a short pipe used to connect two pipes. Also called the outer joint. Because of its convenient use, pipe couplings are widely used in civil construction, industry, agriculture and other fields. The main manufacturing standards for pipe hoops are generally GB/T14383, ASME B16.11, and BS 3799.
The socket pipe coupling is machined by a round steel or steel ingot after machining, and the connection form is Socket Welding-SW. The steel pipe is inserted into the socket to be welded, so it is called “Socket tube hoop”, the main manufacturing standards are ANSI/ASME B16.11, GB/T 14383.
The types of socket ferrules include double socket ferrules and single socket ferrules. Among them, the double-mouth pipe coupling has the equal diameter and the different diameter, and the double-diameter pipe clamp of the different diameter has the concentricity and the eccentricity.
The socket pipe couplings are respectively located at the two ends of the curved portion; compared with the prior art, the design is reasonable, the operation is simple, the utility is strong, and the operation quality and convenience are improved.
The socket pipe coupling can be widely used in pipes of different calibers, including single pass, three-way, four-way, etc., and can also be used for water meters and valves. Due to the use of the socket structure, the pipe joint reduces the cost, is extremely convenient to install, use and maintain, and has a high leakage resistance.
5. Cap
The socket cap is welded to the pipe end, or the threaded pipe cap is mounted on the external thread of the pipe end to cover the pipe fitting. They are used to close the pipeline and function the same as the plug. The production standard is GB/T14383 ASME B16.11.

7. Hex Head Bushing
Hex Head Bushing, also known as the core, is usually made of hexagonal bar after forging and is a common accessory for different diameter threaded pipes. It has an irreplaceable role in pipe connection. Because the outer hexagon is easy to tighten and tighten, there are many types of threads used for connection. The common type is NPT RC threaded connection.

8. Swage Nipples
The differences between the swage nipple and the reducer
1. Size ranges
The size range of the reducer is wide. The current size standard of the reducer is from DN15 to DN3400 (from 1/2 ” to 136″), while the specification of the swage nipple is from DN6 to DN300 (from 1/4 ” to 12″).
2. Raw materials
Seamless steel pipes or steel plates are used as raw materials for reducers, while round bar steel or billet steel is selected as the raw material forswage nipples.
3. Manufacturing processes
The manufacturing process of the reducer is that we adopt the heat pressing process or the cold pressing process for the seamless reducer(the heat treatment is required for the cold pressing process) and we adopt the hot rolling process for the other reducer. The manufacturing process of the swage nipple is the forging process.
4. Connection ends
Beveled ends are basically adopted for reducers, and plain ends are hardly adopted for reducers. Although the plain end are allowed to be used for the stainless steel or the carbon steel reducer product whose wall thickness is lower than a certain amount. Swage nipples have more connection ends, and two ends of swage nipples can be the same or different based on the requirements of sites or designs; connection ends of swage nipples can be divided into beveled ends, plain ends and threaded ends three kinds. The following table is a good introduction to the connection end of the swage nipple.
Different connection ends of swage nipples
Specifications | |||
1. When we select the swage nipple, we should mark the end. We should also mark NPT or R for taper pipe threads. | |||
2. Big ends and small ends of swage nipples can be divided into plain ends, beveled ends and taper pipe threaded ends three kinds; the following is a table for nine combinations of big and small ends. | |||
Type | Big End | Small End | Code |
A | plain ends | plain ends | BEP |

I | threaded ends | BET | |
3. Wall thicknesses of swage nipples are generally Sch80 (3000LB) or Sch160 (6000LB). |
9. Sockolet
The sockolet (socket weld outlet) is mainly used for the reinforcing pipe fittings connected by the branch pipe, instead of using the branch pipe type such as the reducer, the reinforcing plate and the reinforcing pipe section, it is safe and reliable, reduces the cost, simple construction, improves the medium flow channel, and series. The advantages of standardization, design and selection are convenient, especially in high-pressure, high-temperature, large-diameter, thick-walled pipelines, which replaces the traditional branch pipe connection method. The main body of the branch pipe is made of high-quality forgings, and the materials are the same as the pipe materials, such as carbon steel, alloy steel and stainless steel. Commonly used manufacturing standards for socket welding pipe stands are ASME B16.11, GB/T 7306, 12716, 14383, MSS SP-79, 83, 95, 97, JIS B0203, B2316.

10. Union
A pipe union is a secure and semi-permanent connection between two pipes. Most pipe unions consist of two pipes connected together via a third piece. All three are threaded to make a firm connection. While unions are similar to couplings, they are generally easier to take apart and allow pipes of different metals to come together safely. This joining method is common in household and commercial pipe systems.
At first glance, a pipe coupling and a pipe union seem very similar. They both connect two pipes together using a male and female threading system. The main difference between the systems comes from the actual method of joining. Two coupled pipes screw together directly, one inside the other. To take the pipes apart, every pipe that connects to the coupled pipe needs to turn. In a full pipe system, this would mean the entire system needs to come apart to remove one pipe.
With a pipe union, the two pipe ends don’t screw into one another—they each screw into a third piece. When one pipe needs to come apart from the other, the union piece simply screws onto one of the two pipes completely. If both ends of a pipe are attached using a union, the pipe may be removed on its own without unscrewing the other pipes in the system.
11. Threaded pipe nipple
A nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.
The length of the nipple is usually specified by the overall length with threads. It may have a hex section in the center for wrench to grasp. A “close nipple” has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads[citation needed] and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple. A barrel nipple or a pipe nipple is one which is usually made from pipe and is threaded only at both ends.. The threaded pipe parts produced meet the American ANSI B16.11 and GB/T14626 standards, and there are three kinds of pipe threads commonly used in engineering pipes :
- ISO7/1 is an international thread seal pipe thread with a profile angle of 55o and a taper of 1:16. The internal thread has two types: parallel (Rp) and tapered (Rc). The external thread has only tapered R. It is usually Rp-R. As shown in Figure a, it is used for public works, and Rc-R is less common. .
- ISO228 is an internationally-used non-threaded sealed pipe thread with a profile angle of 55o. The inner and outer threads are all parallel.
- ANSI B1.20.1 is a US threaded pipe thread with a profile angle of 60o (NPT) and a taper of 1:16. The inner and outer threads are tapered and are commonly used for pipe threads in high temperature and high pressure pipes. AMSE B16.11 threaded pipe fittings are commonly used for NPT threads. NPT and ISO7/1 (commonly known as BSP), although the tooth angle is different, the 1/2 and 3/4 gears have the same pitch and can be connected to each other.

What is socket welding?
Socket welding is to weld the pipe into the valve body for welding, and the shape of the internal thread connection is similar after molding. Generally speaking, carbon steel pipes and stainless steel pipes below 2′′ are used for socket welding; but stainless steel pipes 2′′ are also used for butt welding, such as flange flange flanges; titanium pipes, duplex steels, nickel bases. Alloys and the like are basically used for butt welding.
Advantages of socket welding
- There is no problem with the beveling;
- There is no problem with the wrong side;
- The welding position can be adjusted to flat welding .
The difference between socket welding and butt welding
- Socket welds form fillet welds , while butt welds form butt welds . It is better to analyze the butt joints from the strength and stress state of the welds than the sockets. Therefore, in the case of high pressure grades and occasions with poor service conditions, the form of docking should be adopted.
- Socket welding is generally used for small diameters of DN40 or less, which is economical. Butt welding isgenerally used for DN40 or above. The form of socket welding is mainly used for small diameter valves and pipe, pipe fittings and pipe welding. Small-diameter pipes generally have a thin wall thickness, are easy to be misaligned and ablated , and are difficult to weld, and are more suitable for socket welding. In addition, the socket of the socket welding has a reinforcing effect, so it is also used under high pressure. However, socket welding also has shortcomings. One is that the stress condition after welding is not good, the welding is not welded , and there is a gap inside the pipe system. Therefore, the pipe system used for crevice corrosion sensitive media and the pipeline system with high cleaning requirements are not suitable. Use socket welding. Furthermore, for ultra-high pressurepipes, even small-diameter pipes have a large wall thickness, and it is possible to avoid socket welding by usingbutt welding.
- The former must be one big and one small in diameter before it can be inserted into the weld. 1. The latter diameters may be the same or different. 2. The welding groove is different in form. 3 welding process is different. The strength after welding is different.
- Most of the lower pressure grades are smaller socket welds, and the higher pressure grades are often butt welds.Butt welds are 100% tested for flaw detection to ensure no leaks.
- As the name suggests, socket welding is to insert the tube into the welding, but the butt welding is directly welded to the nozzle. Generally, the requirements for butt welding are higher than those for socket welding, and the quality after welding is good, but the detection method is relatively strict. For the welding to do the radiographic inspection , the socket welding can be used for magnetic powder or penetration testing (like carbon steel for magnetic powder, stainless steel for penetration). If the fluid in the pipeline does not require high welding, it is recommended to use socket welding for easy inspection.
