ASTM A105 Forged Steel Pipe Coupling

ASTM A105 Forged Steel Pipe Coupling are used to connect two pipes or tube by screwed (threaded) or socket welding.It is forged by ASTM A105 carbon steel and has high strength and corrosion resistance. It can withstand the operating pressure and vibration of high-pressure pipelines, ensuring the safety and stability of the pipeline.

The Types Of Forged Steel Coupling

Based on the connection method, there are threaded coupling and socket weld coupling.

According to the shape, we can divide steel pipe coupling into straight and reducing coupling.

Based on the length, we can call them as full coupling and half coupling.

What Is The Threaded Coupling

We also named threaded pipe coupling as screwed coupling. They have thread at one or both ends that allows two steel pipes or tubes to be joined. The common thread types are NPT, BSPP and BSPT.

Size: 1/8″ to 4″

Pressure: 3000LB, 6000LB

Standard: ASME B16.11 GB/T 14383 BS3799

Threaded Coupling Dimensions

What Is The Socket Welded Coupling

Same as other socket weld fittings, they are generally used to connect steel pipe which nominal diameter below 4 inch. Socket weld pipe coupling also have full and half coupling.

Size: 1/8″ to 4″

Pressure: 3000LB, 6000LB

Standard: ASME B16.11 GB/T 14383 BS3799 JIS B2316

Socket Weld Coupling Dimensions

In addition to the two main types of socket coupling and thread coupling, ASTM A105 forged steel pipe coupling can also be subdivided into strait coupling, reducing coupling, half coupling,full coupling, and other types based on factors such as diameter and length. Because the types of pipe couplings are diverse and can meet the design requirements of various pipeline systems, they have been widely used in fields such as petroleum, chemical, and power.
