Carbon steel flange is a polygonal ring shell with cross section or a polygonal sector shell with both ends closed. After the inner part is filled with pressure medium, internal pressure is applied. Under the effect of internal pressure, the cross section gradually turns from polygon to circle, and finally becomes a circular ring shell. According to the requirements, the circular ring shell is made into different flanges.

Carbon steel flange in the actual production and research and development to choose different ways and processes for production and production, according to the process methods and principles, for different aspects of important value and effect, in the actual production to add certain elements to increase the characteristics and value of carbon steel flange, reflect good use characteristics and value.
The manufacture of carbon steel flange should meet three requirements: the steel plate should be subject to ultrasonic flaw detection without delamination defect; the steel plate should be cut into strips along the rolling direction of the steel, bent and butt welded into a ring, and the steel surface should form a cylindrical surface of the ring; the butt weld of the ring should be full penetration weld.
