Socket Weld Elbows are forged pipe fittings designed to change flow direction in piping systems through socket-weld connections. Available in 45-degree and 90-degree configurations, they are used in compact piping layouts where secure welded joints and space-efficient installation are required. Size, pressure class, and material options can be specified according to project requirements.
Manufactured to applicable ASME B16.11 requirements, Socket Weld Elbows can be supplied in selected carbon steel, stainless steel, and alloy steel grades.

Socket Weld Elbows are manufactured in accordance with ASME B16.11, with applicable pressure classes and dimensions selected to meet project specifications. Material standards include ASTM A105/A105M for carbon steel and ASTM A182/A182M for applicable alloy steel and stainless steel grades.
Material grade, socket dimensions, pressure class, and dimensional tolerances are controlled according to the specified requirements to ensure proper pipe fit-up and compatibility with the intended piping system. Material certification and inspection can be provided according to project requirements.
Socket Weld Elbows are commonly used in small-bore piping systems where compact connections and reliable welded joints are required. Typical applications include:
Oil and Gas: Auxiliary piping, instrument connections, and selected process lines.
Chemical Processing: Piping systems handling compatible process fluids under specified operating conditions.
Power Generation: Auxiliary systems for steam, water, and other process media, subject to design requirements.
Industrial Process Equipment: Compact piping assemblies, manifolds, and equipment connections.
High-Pressure Piping: Systems designed with suitable fitting pressure classes, materials, and operating conditions.
What is a Socket Weld Elbow?
A Socket Weld Elbow is a forged pipe fitting that changes the direction of flow and connects to a pipe through a socket-weld joint. Common configurations include 45-degree and 90-degree elbows.
Which standard applies to Socket Weld Elbows?
ASME B16.11 covers forged socket-welding and threaded fittings, including applicable dimensions, pressure classes, tolerances, marking, and material requirements.
What pressure classes are available for Socket Weld Elbows?
Socket Weld Elbows under ASME B16.11 use Class 3000, Class 6000, and Class 9000 designations.
What materials are used for Socket Weld Elbows?
Common material specifications include ASTM A105/A105M for applicable carbon steel forgings and ASTM A182/A182M for applicable alloy steel and stainless steel forgings. The exact grade must be confirmed against the purchase specification.
How do I select the right Socket Weld Elbow?
Consider the nominal pipe size, elbow angle, pressure class, material grade, operating temperature, fluid properties, and applicable piping code. Confirm dimensional compatibility and service suitability before ordering.
