Carbon steel flange has the advantages of accurate blank shape and size, small processing capacity and low cost. However, the carbon steel flange has pores, cracks and impurities, and the internal structure of the casting is poor. Its advantage is that it can have more complex shapes and low production cost.
Carbon steel flange, Its carbon content is lower than that of cast flange, so it is not easy to fracture, has compact structure, and can withstand shear force and tensile force. Carbon steel flanges have better mechanical properties.
Diameter: DN50 - DN300
Material: SS304, SS316
Pressure:1.2 - 60Mpa
Standards: ASTM / ANSI, ISO, DIN

Carbon steel flange must be selected according to the service environment and cannot be placed directly on the ground. It is necessary to place some damp proof pads on the ground, and then place the flanges neatly. There shall be a passage between flanges to keep the passage ventilated.
Carbon steel flange are widely used to connect various high, medium and low pressure pipelines, such as urban tap water supply pipeline network, sewer drainage pipeline network, winter boiler heating circulation pipeline, oil and natural gas and other energy pipelines.
