A flange is an external or internal ridge, for strength, as the flange of an iron beam such as an I-beam or aT-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mountof a camera; or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term "flange" is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.

　　A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.

　　We have adopted advanced production equipment and technologies to manufacture our blind flanges weld neck socket flanges slinp on flanges and threadedflanges, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
