Loose sleeve flange is the use of flanging, steel ring and other flange sleeve on the pipe end, the flange can be moved on the pipe end. The steel ring or flanging is the sealing surface, and the function of the flange is to press them. It can be seen that the loose sleeve flange does not contact the medium because it is blocked by the steel ring or flanging.
Loose sleeve flange is suitable for steel, aluminum and other non-ferrous metal and stainless acid-resistant steel container connection and corrosion resistant pipeline.
Loose sleeve flange is a movable flange, which is generally matched on the water supply and drainage accessories (expansion joint is the most common). When the manufacturer leaves the factory, each end of the expansion joint has a flange, which is directly connected with the pipeline and equipment in the project with bolts.
You know, the kind of flange with a looper. Generally used in pipes, that way, loose bolts can rotate both sides of the pipe, and then tighten. Can be more convenient disassembly pipe. Loose sleeve flanges are also called loose sleeve flanges.
There are a variety of sealing surface types of lap joint flange, generally commonly used are protrudent surface (RF), concave surface (FM), concave-convex surface (MFM), mortising surface (TG), full plane (FF), ring connecting surface (RJ).
