Large size Flanges

Large-diameter steel flange is made of carbon steel and stainless steel flanges. Good ductility low carbon intensity is low, after adding suitable amount of carbon will become hard, plastic lower intensity increased. Flange connection may need to withstand very high tensile, compression, torsion, shear strength, carbon steel flange is the better choice. Independently developed by the factory cold Volume flange equipment and advanced technology. Portland opened up a law without CALCINED made the production of welding and many of the processes, raw materials, forming a one-time, that is, to speed up the production process and efficiency, while product quality has been ensured.
