Applications:
Flange joints are an extremely common and widely used component in engineering design. It is piping design, pipe fittings valves essential parts, but also equipment, equipment parts (such as manhole, sight glass liquid level meter, etc.) in the necessary components. In addition, other professions such as industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control, etc., also often use flange joints.
Material:
Forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, molybdenum-ditanium, rubber-lined, fluorine-lined materials.
Classification:
Flat welding flanges, necked flanges, butt welding flanges, ring connection flanges, socket flanges, and blind plates, etc.
Execution standard:
GB series (national standard), JB series (Ministry of Machinery), HG series (Ministry of Chemical Industry), ASME B16.5 (American Standard), BS4504 (British Standard), DIN (German Standard), JIS (Japanese Standard).
International pipe flange standard system:
International pipe flange standard mainly has two systems, namely, Germany DIN (including the former Soviet Union) as the representative of the European pipe flange system and the United States ANSI pipe flange as the representative of the American pipe flange system.
In addition, there is the Japanese JIS pipe flange, but in the petrochemical plant is generally used only for public works, and in the international influence is small.
