Plate Flange Welding Plate Pipe Flange

Plate Flange Plate flange features high accessibility of its raw materials,easy manufacturing,low cost and good comprehensive performance,Hence,it is widely used in many fields such as chemical industry,construction industry,water supply system used in many drainage system,petroleum industry,heavy and light industry,refrigeration industry,hygienic industry,water heating system,fire protection sector,power supply industry,aerospace industry and shipbuilding industry,However,the flange is not suitable for piping system which requires high vacuum degree,flammable and combustible situations and extremely hazardous occasions.
