High-pressure flange is to use the plastic deformation of the gasket to reach the sealing effect, connected to the pipe end, so that the pipe and pipe connected to the parts, the flange has a hole, the double head bolts to make the two flange tightly connected. High-pressure flange is a kind of high pressure, high temperature, high corrosion in the environment to connect the new type of pipe flange, in the industrial application has the following advantages, we understand.
1, the gate and seat sealing surface with iron base alloy surfacing or the division of cobalt base cemented carbide surfacing, wear-resistant, high temperature, corrosion resistance, abrasion resistance and long service life.
2, can be used a variety of pipe flange standards and flanged sealing type, to meet a variety of engineering needs and user requirements.
3, high-pressure flange seal ring long using metal material, because it is the core of the flange, so to ensure that the seal ring in the role of external forces, free eyes, forming a seal, so that high-pressure Falancai can withstand the strength of the connection site.
4, high-pressure flange valve stem by the adjustment and surface nitriding treatment, has a good corrosion and abrasion resistance.
5, high-pressure flange connection steel gate valve in line with domestic and foreign advanced standards, reliable sealing, excellent performance, handsome in appearance.
6, the gate valve uses the wedge type elastic gate structure, in the large diametersets the rolling bearing, the friction is small, the opening and closing is relaxed.
