Various pipe fittings which are ASME B16.11 Socket Weld Coupling, Threaded Elbow and ASME B16.9 Equal Tee were export to Malaysia.

A client from Malaysia was interested in the A182 F22 Coupling on our website, and found it was exactly what he needs, so he sent us an inquiry that include the Alloy Steel Pipe Coupling, Galvanized Equal Tee A234 WPB and SS304 Threaded Elbow. And highlight the delivery time is tight.

While the offer is sent to customer, we remark that Full Coupling and Equal Tee in stock. But equal tee need to be galvanized. 45 Degree Elbow can be ready while the tee finished of galvanizing in the email.

At the same time, we checked the shipping schedule for ETD and ETA.

Customer is happy with professional arrangement and confirmed the order in several days after negotiation.

ASME B16.11 Coupling is a common fitting in industrial pipeline connection. The coupling or socket is a nipple for connecting two pipes. Coupling is widely used in civil architecture, industry,agriculture and other fields since it is convenient. The main manufacturer standards also have GB/T14383,  and BS 3799.

There are two types of Coupling or socket, Socket Weld Coupling and Threaded Coupling. DN32 SW Coupling  A105 3000#, 3/4” SW Coupling A182 F22 CL3 and 3/4″ Half Coupling BSPP SS316,  2″ Forged Steel Coupling NPT Class 3000 A105.

Socket Weld Coupling or Socket

The ASME B16.11 Coupling socket weld is forged by round bar or ingot mold and then machined.  Put the pipe into socket hole and weld, that is socket weld connection. Therefore, its name is socket weld coupling or socket weld socket. The size is from DN6 (1/8”) to DN100 (4”) with pressure 3000lb, 6000lb and 9000lb.

Threaded Coupling or Socket

The ASME B16.11 Coupling threaded  is forging and has types of coupling NPT, socket BSPP, coupling BSPT. Both of their standard is ANSI/ASME B16.11、GB/T 14383.It has NPT and BSP( BSPP and BSPT). The size is from DN6 (1/8”) to DN100 (4”) with pressure 3000lb and 6000lb.

Both of them have two types, half and full coupling. For full couplings, there are equal and reducing coupling. And reducing couplings have Eccentric and Concentric.

The material is Carbon Steel, Alloy Steel and Stainless Steel. People also call them as Socket in some area or country. For example, Half Socket 1/2″ 3000lb BSPT A105, SS316 Socket 1″ BSPP 3000lb .or 1 1/2″ SS316L Coupling 3000lb NPT . The application of Socket is widely, including pipeline in different sizes, Pipe Tee, Cross Tee, etc and water meters and valves. Due to using socket structure, the pipeline joints reduce cost make installation, use, maintenance is extremely convenient, but also has a very high leak-proof ability.

Socket welding is a pipe connection method for inserting pipe into valve,fittings and flange. It is usually used for 2-inch or below.

Socket welded joint is a good choice when the high structural strength requirement and high leakage risk become design considerations.

The fatigue strength of the socket weld joint is lower than butt weld joint because of the mutation of the filled weld and the geometrical structure. However, socket welded joint is superior to other mechanical joints.

Socket weld pipe fittings are high pressure which applied in various industrial processes, the features are as below

1. Used in transferring flammable medium without leakage, poisonous or expensive medium and 300PSI to 600PSI steam
2. It is only connected to the ASME Pipeline with the same diameter.
3. Used in piping permanent work and provide better flow characteristics.
4. The materials are ASTM, and standards are ASME B16.11 whcih including pressure-temperature ratings, dimensions, tolerances, marking and carbon steel, stainless steel and alloy steel material requirements. It can be forgings, round rods, seamless pipe. Common materials are ASTM A105, A182 or A350

There are three pressure rating. Class 3000, 6000, 9000

Forged Socket Weld Fittings

Advantages

1. Beveling is not necessary
2. Spot welding is not necessary
3. The weld material will not penetrate into the pipeline hole.
4. Allow to instead threaded pipe fittings, and reduce the risk of leakage.
5. The fillet weld is not suitable for radiographic inspection, so proper fitting and welding is critical. Fillet weld usually use magnetic particle and penetrate to do surface detection.
6. The cost is lower than butt weld

Socket Welding Fittings

Disadvantages

1. Welder shall ensure the welding expansion space between pipe and socket shoulder 1.6mm during welding.
2. The existence of cracks in welding gap and socket weld, which reduces the corrosion resistance or radiation resistance of the pipeline. When the solid particles are piled up at the socket weld, the pipeline operation and maintenance may fail. In this case, the entire pipe is usually required to be fully welded butt welds.
3. Socket welding does not apply to ultra-high pressure food industry. Because it is not fully welded, leaving overlap and cracks, it is difficult to clean, the formation of false leakage.
