china PL Flange is the most common flange at present. In popular terms, it means inserting the pipe into the flange for welding. Now because it has a lot of good comprehensive performance, it is well used in life. In our daily life, we often see china PL Flange being used in chemical industry, construction and other places. Of course, there are also some places where plumbing and fire protection are also applied. Therefore, it can be used in large-scale buildings in China. Now china PL Flange has flat and raised faces.

　　china PL Flange: easy to obtain, simple to manufacture, low cost, and widely used; but poor rigidity, so it should not be used in chemical process piping systems and highly and extremely hazardous materials that require supply and demand, flammability, explosion and high vacuum degree. occasion. The sealing surface types are flat and raised.

　　China PL Flange is the most common flange, the pressure is PN2.5, PN6, PN10, PN16, PN25.

　　Welding form: plate flat welding flange is to insert the pipe into the flange to weld.

　　The material of flat welding flange: 201, 304.316.316L.0Cr18Ni9.321.202, carbon steel, 20#, 20G, and alloy steel, etc.

　　china PL Flange Scope of application: Due to its good comprehensive performance, the plate-type flat welding flange is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding, etc. basic engineering.
