FAQ

What are stainless steel flanges used for?

Stainless steel flanges are used to connect pipes, valves, pumps, and other equipment in a piping system. They provide easy access for cleaning, inspection, and modification. Flanges are also used to seal vessel openings or piping systems, especially in low-pressure applications, and allow for regular maintenance or inspection.

What are the standards for stainless steel flanges?

Stainless steel flanges are governed by standards such as ASTM A182, which specifies material grades like F304/L and F316/L. These flanges come with various pressure ratings, including Class 150, 300, 600, and up to 2500, ensuring suitability for different industrial applications and pressure requirements.

What is the use of SS flange?

Stainless steel flanges are used to connect pipes, valves, pumps, and other equipment within a piping system. They are ideal for low-pressure applications and can be fillet welded in place. Blind flanges, without a bore, are used to seal vessel openings or piping systems that require regular inspection.
