Carbon steel flange is the use of characteristics and maintenance can be said to be very important, in the use and maintenance of standard flange need to pay attention to many things, need to be used in accordance with certain methods, in accordance with the accurate and fair method of use and maintenance. Some unscrupulous businessmen will reduce the thickness and outer diameter of the flange to achieve the purpose of saving materials. They also use scrap steel or leftover steel to process the flange. Generally, this kind of steel is unqualified in chemical composition and mechanical function. What's more, they use heigang's private steel-making to produce the flange. The steel-making skills used in this kind of private steel-making are old, which can't ensure the mechanical function and welding function When using, it may not be able to weld with the steel pipe, or the steel itself may have cracks, pores, etc., and it may leak after welding.

Carbon steel flange is produced in the billet cold forging, deformation and work hardening phenomenon will occur, will make the forging die bear a high load, so in the casting, we need to use high strength forging die, and choose to avoid wear and adhesion of hard lubricating film to deal with. In addition, in order to avoid cracks in the blank of carbon steel flange, the central annealing process is also needed, so that the carbon steel flange can resist deformation.
