Lap joint flange

lap joint flange is a flange can be activities, generally supporting the drainage accessories (the most common slip joint), the factory expansion joints at both ends have a flange bolt connection pipeline, directly and in engineering equipment. Commonly used as a connection is the change of material. Loose flange is the use of flange, steel ring and so on the flange on the pipe end, flange can be on the pipe end activities. Steel ring or flange is the sealing surface, the role of the flange is to compress them. Loose flange for steel, aluminum and other non-ferrous metals and stainless acid resistant steel container connection and corrosion resistant pipeline. Generally used in the pipeline, then loosen the bolts can rotate on both sides of the pipeline, and then tighten. Loose flange is also called the flange.
