High pressure carbon steel flange steel high pressure flanges performance superior quality, wear-resistant, easy to damage. High pressure steel flange size is 1 / 2-10 inch pipe fittings are widely used in petroleum, chemical, metallurgy, electric power industry, devices, and other ancillary services. And generally do not add a lot of steel alloying elements, mainly referring to the mechanical properties of carbon steel depends on the carbon content. Sometimes referred to as carbon steel or carbon steel. Carbon steel, also known as carbon steel, carbon content refers W3 is less than 2% iron-carbon alloys. Determining principle of the heating temperature high pressure carbon steel flanges are material austenitizing temperature. The higher the heating temperature; high temperature material yield limit, the higher the heating temperature. And the inner wall of the main flange is less than the yield stress limit at this temperature when the push system. Steel high-pressure flange pipe specifications can only do if too large, it is difficult to buy scrap flanges, welded flanges use only. Because welding flange welds more, all using performance as flanges, easily corroded drain. Insulating flange connections for use on stainless steel and carbon steel connection joints, dissimilar domestic steel material change, like direct dissimilar steel welding, there is through the flange connection, but they are not considered material that exists between these two different potential difference, there will be a potential difference exists corrosion. Domestic design seems to have no more aware of this, foreign engineering basically adopt this connection, insulation. The difference between the high-pressure carbon steel flange has a hardness and strength in the use and production, the guarantee can probably play a role tension in utilization and costs. Material differences between the high-pressure carbon steel flanges can probably play the advantages and features of the differences in the use of low-intensity low-carbon steel, good plasticity. Flanged have probably suffered necessary high tensile, compression, torsion, shear strength, according to making sure that the use of examples and essentials for sealed with duct plugs. Essential difference between the flange and the production configuration information held production in production, flange covers production as follows: the flange is no hole in the middle of the flange. You can probably guarantee good performance and performance advantages, to be held in strict accordance with the production process and the essentials for sure when production.
