ASME B16.11 Socked Weld Elbow

ASME B16.11 Socked Weld Elbow SW

ASME B16.11 Socked Weld Elbow SW Manufacturer

Socket Weld Elbows are forged steel fittings used to change the direction of flow in small-bore piping systems. Manufactured according to ASME B16.11, these elbows are designed for high-pressure and high-temperature service where strong, leak-proof connections are required.

They are commonly available in 45° and 90° angles and are joined to pipes by socket welding, ensuring excellent strength and resistance to leakage.

What is a Socket Weld Elbow?

A Socket Weld Elbow is a forged pipe fitting used to change the direction of flow in small-diameter, high-pressure piping systems. It is designed according to ASME B16.11 and is available in 45° and 90° angles.
