Material standards

A flange joint is a widely used component in engineering design, involving a wide range of aspects. It is an essential component in piping design, pipe fittings, and valves, as well as an essential component in equipment and components such as manholes, sight glasses, and liquid level gauges. In addition, flange joints are often used in other professions such as industrial furnaces, thermal engineering, water supply and drainage, heating and ventilation, and self-control.
Material of flange:
Forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum titanium, rubber lining, fluorine lining materials.
Classification of flanges:
Flat welding flange, neck flange, butt welding flange, ring connection flange, socket flange, and blind plate, etc.
Execution standards:
There are GB series (national standard), JB series (mechanical department), HG series (chemical department), ASME B16.5 (American standard), BS4504 (British standard), DIN (German standard), JIS (Japanese standard).
International pipe flange standard system:
There are two main international pipe flange standards, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flanges.
