FLANGES

Flanges

Flanges is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pump, valve, pressure vessel or any other piece of equipment. Stainless Steel Flanges And Carbon Steel Flanges & Alloy Steel Flanges provide easy access for modification, cleaning or inspection. They usually come in various shapes, Pressure Rating, Weight Chart, Dimensions, size, grades & specifiaction with ANSI/ ASME, EN, BS, DIN standards. The Flanges are joined to each other by bolting and joined to the piping system by threading or welding and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.
