SW Socket Weld Flanges

A socket flange, commonly called a socket weld flange, has a recessed area that receives the pipe end. The pipe is positioned inside the socket and welded externally to create the connection. These flanges are used in industrial piping systems, pipeline applications, construction and welding, hydrostatic testing, petrochemical projects, and maintenance work.

The listed material options include carbon steel, stainless steel, alloy steel, duplex, and nickel alloys. Material selection should be matched to the piping service, operating conditions, compatibility requirements, and project specifications. Twinco can help customers identify an appropriate available option based on the required material and application.

The product information lists ASME B16.5 and ASME B16.47 Series A and B standards, along with API standards. Listed ASME pressure classes include 150, 300, 400, 600, 900, 1500, and 2500. API ratings are listed from 2,000 to 15,000 PSI. Confirm the required standard and rating when requesting a quote.

Yes. The listed ownership options are rental and purchase. Rental can support hydrostatic testing, maintenance, and project-based requirements, while purchase may suit recurring industrial piping, pipeline, petrochemical, construction, and fabrication needs. Availability depends on the requested flange type, material, size, standard, and pressure class.

SW Socket Weld Flanges are listed for pipeline applications, industrial piping systems, hydrostatic testing, petrochemical projects, construction and welding, and manufacturing maintenance. They can support connection, testing, isolation, fabrication, and repair requirements when the flange design aligns with the project’s piping specification and operating conditions.

Provide the required flange type, nominal size, material, standard, pressure class or API rating, quantity, application, and whether you need purchase or rental. The listed product range extends from ½″ through 72″, with multiple materials and flange types available. Sharing complete specifications helps Twinco evaluate the appropriate option.
