Chiho Hebei Industry Marine flange for a flange on the vessel, the tube and the tube flange is interconnected parts. Connected to the pipe end. There are perforations can be worn bolts, so that the two flange abuts the flange. Between flange sealing gasket. Flange connection is the two pipes, fittings or equipment, the first in a fixed each flange on, between two flanges, with flange pad, fastened together with bolts to complete the connection. Some fittings and equipment has been carrying flange, also belong to the flange connection. Hebei Industry Chiho large welded flange: Alloy Steel Flanges use easily obtained, create a simple, low cost, widely used; however, less rigid steel flange, and therefore can not be used there is supply and demand, flammable, explosive chemical process piping systems and high 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, electrode consumption Multi-alloy steel flanges, can not withstand high temperature, high pressure, repeated bending and temperature fluctuations role alloy steel flange manufacturers, are generally used PN≤2.5MPa, at room temperature, the working temperature of the pipe t≤0 ℃ Wrought alloys steel flanges | Hebei Chiho (certified) | by Hebei Steel Flanges Chiho Industry Co., Ltd.
