Correct socket weld fitting selection is critical to ensuring a leak-free high-pressure piping system and long-term operational safety. The fitting type, material grade, and pressure class must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing a socket weld fitting:
If you are unsure which socket weld fitting specification best suits your application, our technical team is available to review your piping drawings, process data, and project specifications — and recommend the most suitable socket weld fitting solution.
