A flange is a disc-shaped connecting component manufactured through precision stamping, forging, and machining processes. Its core function is to provide a detachable, rigid connection between pipes, valves, pressure vessels, and equipment bodies.
A flange is a disc-shaped connecting component manufactured through precision stamping, forging, and machining processes. Its core function is to provide a detachable, rigid connection between pipes, valves, pressure vessels, and equipment bodies, while also providing sealing, load-bearing, pressure resistance, and vibration resistance.
Flanges can be supplied in conjunction with metal stamping/sheet metal parts (such as pipe supports and equipment housings), supporting full-dimensional non-standard customization, and are widely used in industrial fields such as petrochemicals, new energy, water treatment, and engineering machinery.
