What are the application characteristics of high-pressure flanges?

High pressure flange is a flange used to connect pipes or equipment with a pressure greater than 10 MPa. Currently, it mainly includes traditional high-pressure flanges and high-pressure self-tightening flanges.
Traditional high-pressure flange: The plastic deformation of sealing gasket (oval gasket, octagonal gasket, lens gasket, etc.) is used to connect to the pipe end, so that the components and flanges that connect the pipe to the pipe are provided with holes, and the two flanges are firmly connected with studs.
High pressure flanges typically consist of a pair of flanges, a gasket, and several bolts and nuts. The seal is installed between two flange sealing surfaces. Tightening the nut will achieve a specific pressure on the sealing surface, causing plastic deformation and leaving no gaps at the joint. This format can be used for flammable, explosive, toxic media, and high pressure situations, but the sealing reliability is poor.
What are the product characteristics of high-pressure flanges?
1. The sealing principle belongs to plastic deformation.
2. Bolting
3. Bolts bear many external stresses such as tension, temperature difference stress, bending moment, torque, and so on.
4. Large volume and heavy weight make installation and positioning very difficult.
5. Unstable sealing performance. Especially under severe conditions (high temperature, high pressure, and highly toxic media), leakage is prone to occur, leading to serious consequences.
What are the application characteristics of high-pressure flanges?
High pressure flange is mainly used for pipeline installation. High pressure flange connection is an important connection method for pipeline construction, and it plays an important role and value in the connection between pipelines. High pressure flange connection refers to fixing two pipes, pipe fittings, or equipment to a flange, adding flange pads between the two flanges, and tightening them with bolts to complete the connection. Some accessories and equipment already have their own flanges and flange connections. High pressure flange product performance:
1. Wear resistance: The content of Al2O3 in the inner ceramic layer of ceramic composite steel pipes exceeds 95%, and the microscope is also HV1000-1500. With good wear resistance, it is more than 10 times higher than the wear-resistant and durable medium carbon steel, and superior to tungsten carbide.
Corrosive ceramics are neutral materials with stable chemical properties, excellent internal appetite and acid resistance, and can resist various inorganic acids, organic acids, organic solvents, etc. Their corrosion resistance is more than 10 times that of stainless steel.
