Application of Ji Meng welding flange
Welding neck flange is mainly used for the flange and pipe butt welding, reasonable structure, strength and stiffness is larger, can withstand the high temperature high pressure, and repeated bending and temperature fluctuations, sealing reliability. Nominal pressure is 0.25 ~ 2.5MPa welded flange with concave and convex type sealing surface. Butt welding flange has extensive use and promotion in the pipe, in accordance with the need to use the corresponding ways and methods.
Welded flange refers to the neck and flange and connected with the transition tube pipe butt welding. Welded flange is flanged fittings in a, widely used in various fields and industries and promotion, in the use of applicable scope of different, require the use of the environment is different and need to according to the certain conditions of use. Welded flange applicable to nominal pressure is not more than 2.5MPa steel pipe connections, plays an important role and value in the pipeline links, but in use must guarantee nominal pressure in a certain range. Welded flange sealing surface can be made smooth type, three kinds of bump and tenon slot, smooth type welding flange of the largest amount of applications. For medium conditions more relaxed, such as low non clean compressed air, low pressure circulating water and its advantages are relatively cheap price. Welded flange used in pipeline pressure or temperature fluctuations in the pipeline or high temperature, high pressure and low temperature, are also used for transportation of expensive, flammable and explosive medium pipeline.
Welding and butt welding flange connection flange and pipe welding, welding flange when just one side welding does not need to be welded pipe and flange connection in the mouth, welding flange welded flange welding by both sides need to be installed. Welded flange in use welding orientation and link weight oriented need according to the certain methods used in use need to be used in accordance with the corresponding method.
