Forged Socket Weld Fittings are high-strength forged connectors designed for small-diameter, high-pressure piping systems. Pipes are inserted into the recessed socket and fillet welded, forming a strong, leak-free joint. These fittings ensure precise alignment, reduce stress fatigue, and offer excellent flow characteristics.
FORGED FITTINGS – SOCKET
Structural Features:
A Socket Weld Fitting (commonly referred to as “Socket”) is a type of high-pressure forged fitting used to connect pipes by inserting the pipe into a recessed area of the fitting and then welding.
Socket fittings offer strong, leak-free joints with excellent flow characteristics and are ideal for small-diameter, high-pressure applications.
The design ensures proper alignment and weld reinforcement, reducing the risk of cracking or fatigue under stress.
Common Types of Socket Weld Fittings:
Socket Weld Elbow (90° / 45°)
Socket Weld Tee / Cross
Socket Weld Coupling / Half Coupling / Reducing Coupling
Socket Weld Union / Cap / Plug
All types conform to precise dimensional tolerances for secure and stable connections.
Standards:
ASME B16.11
MSS SP-79 / SP-83 / SP-95
BS 3799 (optional)
Pressure Ratings:
Class 2000 / 3000 / 6000
Suitable for high-pressure, high-temperature pipelines
Applications:
Socket weld fittings are commonly used in:
Oil & Gas pipelines
Refineries and chemical plants
Power generation facilities
High-pressure steam systems
Shipbuilding and offshore platforms
Instrumentation and control lines
Common Materials:
Carbon Steel (ASTM A105)
Stainless Steel (ASTM A182 F304, F316)
Alloy Steel (ASTM A182 F11, F22)
Also available in Duplex, Monel, Inconel, and other exotic materials upon request
Recommendation:
Socket fittings are ideal when compact layout, strong weld joints, and high integrity sealing are required.
They are easy to align, provide excellent fatigue resistance, and are widely chosen for small-bore, high-pressure piping systems where leak prevention and long-term durability are critical.
