Application of loose Plate Flange

　　Loose plate flange are flanged, steel rings and so on, and flanges are sleeved on the ends of pipes, and loose plate flange can be moved on the ends of pipes. Steel rings or flanges are sealing surfaces, and the role of flanges is to compress them. It can be seen that the loose flange is not contacted with the medium because it is blocked by steel rings or flanges.

　　Generally used in pipelines, in that case, loosening bolts can rotate both sides of the pipeline, and then tighten. The pipe can be disassembled conveniently.

　　Loose plate flange is often used in medium temperature and pressure are not high and the dielectric erosion is strong. Loose plate flange is usually combined with flanging knuckle, that is, flange ring loose sleeve outside flanging knuckle, pipe and flanging knuckle butt welding connection, flange sealing surface processing in flanging knuckle. In addition, there are flat welding ring and butt welded ring loose plate flange. Because loose plate flange itself does not contact with the medium, only the flange knuckle or the welding ring and pipe are the same, the material of the flange body can be completely different from the pipe, so it is especially suitable for corrosive medium, can save stainless steel, non-ferrous metal and other valuable corrosion-resistant materials. In water supply and drainage fittings, such as expansion joints on the most common, manufacturers on both ends of the expansion joints have a loose flange, directly connected with the project pipeline, equipment bolts
