Custom Flat Flange Main function of flange: Flange is a kind of ring made of materials that can produce plastic deformation and have certain strength. Most flanges are cut from non-metallic plates or manufactured by professional factories according to the specified dimensions. These materials include asbestos rubber sheets, asbestos sheets, PTFE sheets, polyethylene sheets, etc., as well as flanges made of asbestos and other non-metallic materials wrapped with thin metal sheets (white iron sheets, stainless steel), low-pressure small-diameter threaded flanges, and high-pressure and low-pressure large-diameter metal wires use welded flanges. Flange thickness, diameter and number of connecting bolts vary with pressure. Common integral flanges of large flanges include flat welding flanges and butt welding flanges. The rigidity difference of the flat welding flange is applicable to the occasions where the pressure P 鈮?4MPa. Butt welding flange, also known as high neck flange, has high stiffness and is suitable for occasions with high flange pressure and temperature. There are three kinds of flange sealing surfaces: plane sealing surface, which is suitable for occasions with low pressure and non-toxic medium; Concave convex sealing surface, suitable for occasions with slightly higher pressure; Tenon sealing surface; It is suitable for inflammables and explosives. For toxic media and high-pressure occasions, flange fittings with different performance have good product performance in different fields. Different applications and spaces will produce different effects. Cut the large flange and intermediate plate into strips and roll them into a circle. Then deal with water pipes, bolt holes, etc. Usually this is a large flange with a maximum length of 7 meters. This kind of flange has good quality assurance, because the raw material is medium density plate, and the material is carbon steel, stainless steel, alloy steel, etcCustom Flat Flange website:http://www.sy-exports.com/flat-flange/
