Carbon Steel Socket Weld Cap (CS SW Cap) is a high-pressure forged pipe fitting used to seal pipeline ends in small bore industrial piping systems.
Designed according to ASME B16.11 and BS 3799 standards, socket weld pipe caps provide leak-free closure, high mechanical strength and long service life in critical pipeline environments.
These forged fittings are widely specified in oil & gas transmission pipelines, refinery process units, petrochemical plants and power generation facilities.
Pressure ratings up to Class 3000 / 6000 / 9000
Forged ASTM A105 carbon steel construction
Precision machined socket bore for tight welding fit
Smooth internal flow transition
High resistance to vibration and pressure fluctuations
Compact design for instrumentation and utility pipelines
Socket weld pipe caps are preferred for SCH80 and SCH160 high pressure piping applications.
