Stamping flange and high pressure flange

In general, the high-pressure flange has good corrosion resistance, which is one of its excellent characteristics. The general high-pressure pipeline will require its corrosion resistance, acid, alkali, salt and other properties, and can resist various inorganic acids, organic acids, organic solvents and so on. Its corrosion resistance is much better than that of the general stainless steel flange. However, in some large flanges, manholes and other products, due to the requirements of diameter, cost or inner diameter, stainless steel is more often used. Stamping flange is a kind of flange production technology that makes the raw materials of flange directly subject to deformation force and deform in the mold with the help of the power of conventional or special stamping equipment, so as to obtain a certain shape, size and performance. Flange raw materials, dies and equipment are the three elements of stamping flange processing. Flange stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping flange. One of the main methods of metal plastic processing (or pressure processing), also belongs to material forming engineering technology. Among the steel products of globegroup, 5060% are made of plates, most of which are finished products after pressing. There are also a large number of stamping flanges in stamping instruments and meters, household appliances, office machines, safekeeping utensils and other products, such as automobile body, radiator, drum of steam pot, shell of container, iron core silicon steel sheet of motor and electrical appliance.
