What is a Flange?

An Industrial Pipe Flange can be a collar, ring or solid disk that attaches to various pipe applications that allow or restrict the flow of liquids and gases. Pipe Flange installment is usually completed by welding the Flange onto the pipe but the Industry also offers Threaded and Lap Joint Flanges that don’t require welding for installment.

Flange connections are achieved by drilling equally spaced bolt holes into the Flange that align with the matching Flange and then fastened with bolts. Bolt hole patterns are determined by Industry Specifications or customer request. Flanges are usually manufactured based on Industry Specifications established by ANSI B16.5, ASME B16.47, MSS-SP44, API, and AWWA-C207.

Custom and Project Oriented Flanges are gaining popularity as new technology and equipment is constantly being developed.
