Carbon steel threaded flange is the connecting pipe fitting of two large-diameter pipes. Usually, two flange plates are added with several fastening bolts. It has good plasticity and low strength. After adding an appropriate amount of carbon element, it will become hard, reduce plasticity and enhance strength.
Pressure:150-1500Lbs
Size:DN15 (1/2") to DN5000 (200")
Standard:ANSI, DIN, GB, ISO, ASME

Carbon steel threaded flange connection needs to bear high tensile, compressive, torsional and shear strength. It is convenient to obtain materials, simple to manufacture, low cost, widely used, but poor rigidity. Therefore, it shall not be used in chemical systems and hazardous occasions with flammable, explosive and high vacuum requirements.
Carbon steel threaded flange is widely used in water conservancy, electric power, power station, pipeline fittings, industry, pressure vessel and other industries.
