Hebei Chiho large welded flange tube industry: easily obtained, create a simple, low-cost large-type carbon steel flanges, widely used; however, less rigid carbon steel flanges sales, and therefore can not be used there is supply and demand, flammable, chemical process piping systems and highly explosive and high vacuum requirements, extremely hazardous situations. sealing surface with flat-screen and projection surface. advantages of large welded flange is to create simple, low cost, but a large amount of welding work, welding consumption, can not withstand high temperature, high pressure, repeated bending and temperature fluctuations effect, generally used PN≤2.5MPa, ambient temperature alloy flanges, pipe t≤0 ℃ operating temperature of Hebei Chiho tube industry; Large plate welded flange main dimensions and connecting dimensions reference plate flat welding flange (flange) connection is the two pipes, fittings or equipment, the first in a fixed each flange plate, between two flanges, plus flange pad, fastened together with bolts to complete the connection. Some fittings and equipment has been carrying flange, also belong to the flange connection. Flanged connections are important pipeline construction. Large plate flat welding flange Flanged easy to use, able to withstand greater pressure .. large type carbon steel flanges, carbon steel flanges, 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.
