Hebei Chiho Pipe flange connection is the two pipes, fittings or equipment, the first in a fixed each flange plate, between two flanges, plus flange gasket forged carbon steel flanges, bolts Forged flange fastened together to complete the connection. Some fittings and equipment has been carrying flange, also belong to the flange connection. Flange threaded connection points (wire tapping) flange and welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange thickness and bolt diameter and the number of different connection flange pressures are different. Depending on the level of pressure, the flange gasket there are different materials forged stainless steel flanges from the low pressure asbestos mats, rubber mats, asbestos mat high pressure to the metal pad has. Flanged easy to use, able to withstand greater pressure. In industrial pipe, using a wide range of flange connection. Hebei Chiho large welded flange tube industry: easily obtained, create a simple, low cost, widely used; but less rigid, and therefore can not be used there is supply and demand, flammable, explosive and high vacuum requirements of the chemical process piping systems and height, extremely hazardous situations. sealing surface with flat-screen and projection surface. advantages of large welded flange is simple to manufacture forged flanges, low cost, but a large amount of welding work, electrode consumption, can not withstand high temperatures , high pressure, repeated bending and temperature fluctuations effect, generally used PN≤2.5MPa, at room temperature, the working temperature of the pipe t≤0 ℃ Hebei Chiho (map), forging flange machining, forging flange made Chiho Hebei Industry Limited. Hebei Chiho Pipe Co., Ltd. (www.hbqh628.com) (www.hbqh628.com) provide customers with "a variety of forged pipe fittings, elbows, tees, reducers, flanges." Business, the company has "Chiho" brands. Focus on forging industry in Hebei Cangzhou higher visibility. Welcomes inquiries, contact: Yang Qinglong.
