High quality flange forming machine with cheaper price. https://www.superdamc.com/channel-roll-forming-machine/ The flange plate is a plate with holes, which is an orifice plate that can seal the end of the pipe. One of the functions of the flange plate is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. As far as the blocking effect is concerned, it has the same effect as the head and cap. But there is no way to disassemble the head, and the flange plate is fixed with bolts, which is very convenient to disassemble. Flange blind plates are made of carbon steel, alloy steel, stainless steel, plastic and so on.
