1. Product Overview
The Carbon Steel Socket Weld Pipe Coupling is a forged pipe fitting used to connect pipes in high-pressure piping systems. The socket weld design allows the pipe to be inserted into the fitting before welding, providing a strong and leak-resistant joint.
Manufactured from high-quality ASTM A105 carbon steel, these couplings offer excellent mechanical strength and durability, making them suitable for demanding industrial environments.
These fittings are produced according to ASME B16.11, ensuring dimensional accuracy and reliable performance in high-pressure pipeline systems.
Carbon steel socket weld couplings are widely used in oil and gas, petrochemical plants, power generation facilities, and other industrial piping systems.

4. Types of Socket Weld Couplings
Socket weld pipe couplings are available in two structural types depending on the installation requirements.
Full Coupling
A Full Coupling has socket weld connections on both ends and is used to connect two pipes of the same diameter in a straight pipeline.
Typical uses:
-
Pipeline extension
-
Industrial process pipelines
-
High-pressure piping systems
Half Coupling
A Half Coupling has only one socket weld connection and is typically welded onto the outside surface of a pipe or vessel to create a branch outlet.
Typical uses:
-
Instrument connections
-
Drain connections
-
Vent lines
-
Small branch pipelines
Structure Comparison
| Type | Structure | Main Function | Typical Application |
|---|---|---|---|
| Full Coupling | Socket weld on both ends | Connect pipes inline | Pipeline extension |
| Half Coupling | Socket weld on one end | Create branch outlet | Instrument connection |
