DESCRIPTION DOWNLOAD

Socket Weld Flanges are used for small-size and high-pressure piping that do not transfer highly corrosive fluids.This due to the fact that these flange types are subject to corrosion in the gap area between the end of the pipe and the shoulder of the socket.Their static strength of socket weld flanges is similar to slip-on flanges’, but their fatigue strength is higher due to the presence of a single, instead of double, fillet weld.For more information, please see the download section on the right.

Frequently Asked Questions (FAQs)

What are the ideal applications for socket weld flanges?

Socket weld flanges are best suited for small-size, high-pressure piping systems that do not handle highly corrosive fluids due to potential corrosion in the gap area.

How does the static and fatigue strength of socket weld flanges compare to other flanges?

Socket weld flanges offer similar static strength to slip-on flanges but have higher fatigue strength due to the single fillet weld, which enhances durability under fluctuating loads.

What materials are available for socket weld flanges?

Our socket weld flanges come in a variety of materials, including 304, 304L, 316L stainless steels, and high-strength alloys like 2507 and 2205, catering to diverse application needs.
