Types and standards of stainless steel flanges

What exactly are Stainless Steel Flanges?

A stainless steel flange is a projecting ridge or rim that is frequently used to spread load or boost strength.

Sectional beams, for example, usually include flanges that bear the majority of the load and are united by a web that joins the flanges. Another component that may be added to pipes to act as attachments is flanges. To disperse the clamping force across a greater area, flanges can be added to nuts and bolts.
