What is a flange?

Industrial pipe flanges can be collars, ring or solid disks that are connected to various pipe applications that allow or limit the flow of liquids and gases. Pipe flange mounting is usually done by welding the flange to the pipe, but the industrial department also provides threads and lap flanges that do not require solder mounting.
ANSI B16.5 carbon steel pipe flange connections are achieved by drilling equally spaced bolt holes in the flange, aligning with the mating flanges, and then bolting them. The bolt hole pattern is determined by industry specifications or customer requirements. Flanges are typically manufactured in accordance with industry specifications established by ANSI B16.5, ASME B16.47, MSS-SP44, API and AWWA-C207.
As new technologies and equipment continue to evolve, custom and project-oriented flanges are becoming more popular.
