Low-pressure small-diameter wire-bonded flanges, high-pressure and low-pressure large-diameter welding flanges are used, the thickness of flanges with different pressures and the diameter and number of connecting bolts are different. According to the different levels of pressure, flange gaskets also have different materials, from low-pressure asbestos gaskets, high-pressure asbestos gaskets to metal gaskets. Flange fittings are controlled according to certain principles and methods in actual production. The use and production of certain materials and raw materials can fully display important roles and performances, and show good value and contribution in industrial use.
1. Divide carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, ppc, etc. by material.
2. According to the production method, it can be divided into pushing, pressing, forging, casting and so on.
3. According to manufacturing standards, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. Flange pipe fittings require strict procedures for production and processing, choose raw materials according to the scope of use of different flanges, choose different process methods and means, and ensure that the produced flanges can show different values and performance in use .
Flange pipe fittings are widely used, and are used in different areas, connecting pipes and pipes, so that the pipes can be unblocked, and ensure the smooth implementation of the walk. Flange fittings are widely used in different applications, and there are different types and methods of connection methods, which can show different performance in use.
