Hebei Chiho high pressure pipe industry self-tightening flange: is a more beneficial high pressure, high temperature, high corrosion and other conditions of new high-pressure flange pipe connections under harsh conditions. Traditional flange gasket by plastic deformation is to achieve a sealing effect, are soft seal, and the core flange of high pressure self-tight seal is unique to the new, which rely on the sealing lip of the sealing ring (T-shaped arm) elastic deform to form a seal, it is hard seal. Use hub, card sets, a combination of high pressure sealing ring bones carbon steel flanges, forming a strong rigid body, the strength of the connection portion of the pipe is far greater than the strength of the base material itself. When pressed, tendons and lips were reinforcing the role of carbon steel flanges and seal the lid, both self-tight seal ①, but also reinforced pipes, greatly strengthened the overall strength of the joints of carbon steel flanges companies, This area is an epoch-making progress! Hebei Chiho Pipe welded flange pressure rating, materials and standards have different properties and characteristics, welded flange in use in accordance with certain principles and ways and means to use, in accordance with the appropriate standards of production and processing, guarantee a good value and action in use. Welded flange pressure rating: 0.6Mpa ~ 32Mpa (150Lb ~ 2500Lb), Material: 201.202.301.302.303.304L.309S.310S, 316.316L.317.317L.321.410.420 and other steel flange forging, Hebei Chiho.
