Stainless Steel Flange 304 Welded Flat Welding Flange Sheet Forging Gb Flange Plate Custom Non-Standard Flange PN10
As welded iron flanges, many customers question whether the quality of welded iron flanges is better than forged welded flanges. Actually iron plate welding quality and the quality of the welding flange forging flange is the same, but the iron plate welding flange exactly what place can not be guaranteed, is also the most insecure iron plate welding flange material, because the process of general, the density of iron plate welding flange is no problem, but in the process of producing, The blank of the iron plate welding flange is rarely tested, so after the production, the material of the iron plate welding flange can not be guaranteed without testing.
Gasket is a kind of ring which can produce plastic deformation and has a certain strength. Most of the gaskets are cut down from non-metallic plates, or made by professional factories in accordance with the specified size, the material is asbestos rubber sheet, asbestos board, ptfe board, polyethylene board, etc. Also useful thin metal plate (iron sheet, stainless steel) asbestos and other non-metallic materials wrapped up made of metal gasket; There is also a kind of winding gasket made of thin steel belt and asbestos belt. The most commonly used is the metal winding gasket made of stainless steel belt and graphite. According to the different use environment, the winding belt can also use asbestos. Ordinary rubber gasket is suitable for the occasion of temperature below 120℃; Asbestos rubber gasket is suitable for water vapor temperature is less than 450℃, oil temperature is less than 350℃, pressure is less than 5MPa occasions, for the general corrosive medium, the most commonly used is acid resistant asbestos plate. In high pressure equipment and pipelines, the use of copper, aluminum, no. 10 steel, stainless steel made of lens type or other shape of metal gaskets. The contact width of high-pressure gasket and sealing surface is very narrow (linear contact), and the processing finish of sealing surface and gasket is high.
