ASME B16.11 3IN 3000# Soket Weld Elbow

Socket weld elbow (SW elbow) has 45 degree and 90 degree types, manufactured in forging processes and also has long radius (LR with 1.5 X OD) and short radius (SR with 1 X 0D) model, it has been a common socket weld fittings that used in the pipelines for changing the fluid directions.

What is Socket Weld Pipe Fittings
ASME B16.11 3IN 3000# Soket Weld Elbow is used for welding pipes and fittings including reducers, tees and elbows. Socket weld pipe fittings are used to permanently join pipes that are inserted into a recess in the fitting, flange or valve. A socket weld fittings is a pipe attachment detail. In this case, the pipe will be inserted in to a recessed area of a pipe, fitting, valve, or flange. In order to join the pipes or valves to the other sections of the pipe, seal welds of fillet type will be applied. So in some cases socket weld fittings is a good choice. This is because the benefits of great structural strength and high leakage integrity would be quite important factors that has to be taken in to consideration when designing your pipeline project.

How to describe socket weld pipe fittings dimensions correctly
In case you place an request for this kind fittings, you need to specify the OD dimensions and with pressure requirements (Or thickness schedule), socket weld fittings pressure ratings usually expressed in class 3000, class 6000, and class 9000. Socket weld pipe fittings usually simplified as SW pipe fittings, so you will see some descriptions like SW elbow, SW tees, SW couplings etc

Socket weld pipe fittings types
Like butt weld fittings, based on material types, socket weld fittings also ranged as stainless steel pipe fittings, carbon steel and alloy steel. Based on applications, it includes socket weld elbow, socket weld tee, and reducing tee, reducers, couplings, and SW flanges etc.

Usage about socket weld fittings
Since these fittings have been termed to be high pressure, they could easily be used in a diverse range of industrial processes.
• Socket weld pipe fittings like elbow, tee, reducers, can be used at pipelines for conveying toxic, flammable, or expensive materials where there would be no scope for leakage to occur.
• Used in conjunction with ASME pipe and for to change to different dimensions.
• Applied in the places where pipe work has been deemed to be permanent. In addition, they have also been designed in a manner which could provide characteristics of good flow.
• Manufactured in accordance with ASTM A234 standards and also could be according to ASME B16.11. This is a standard covers dimensions, pressure-temperature ratings, marking, tolerances, and requirements for materials for carbon steel and forged carbon. In terms of material forms that would be acceptable, those could be bars, forging, seamless tubes, and seamless pipe which conform to the requirements of fittings chemicals, mechanical property, and practices.
