Chiho Hebei Industry Marine flange for steel flange 20 on the vessel flange, tube and pipe flange is so interconnected parts. Connected to the pipe end. There are perforations wear steel flange bolts national standard, so that the two flange abuts the flange. Between flange sealing gasket. Flange connection is the two pipes, fittings or equipment, each mounted on a first flange between two flanges, with high pressure carbon steel flanges flange pad, fastened together with bolts, complete the connection. Some fittings and equipment has been carrying flange, also belong to the flange connection. 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, combination ring seal bones, forming a strong rigid body, the strength of the joints is far greater than the strength of the pipe base metal itself. When under pressure, muscle and strength and sealing lip are starting role, both self-tight seal ①, but also reinforced pipes, greatly enhance the overall strength of the joints, and in this field, is an epoch-making progress! 20 carbon steel flange steel flange _ _ Hebei Chiho Chiho by Hebei Industry Co., Ltd. Hebei Chiho Pipe Co., Ltd. (www.hbqh628.com) (www.hbqh628.com) strong, credible, Cangzhou in Hebei forging industry has accumulated a large number of loyal customers.
