What are the functions of carbon steel flanges

The application characteristics and maintenance of carbon steel flanges can be said to be important. There are many things to pay attention to when using and maintaining standard carbon steel flanges. Users need to follow the correct and fair methods for application and maintenance. Using touch theory and finite element method to solve the touch problem of bolted flange structures. A finite element model of the disc joint structure was established, and the touch conditions and stiffness modification criteria for the disc joint touch were provided.

Flanges produced according to the required standards and public service planning are different from flanges produced without standard standards, which are also known as non-standard flanges (some people call non-standard flanges incorrect). Generally, some unscrupulous merchants will reduce the thickness and outer diameter of the flange to save materials. They also use scrap steel or corner steel to process flanges, which are generally waste materials with chemical composition and mechanical properties that are not qualified. Some even use black steel mills to produce flanges. The steelmaking skills used in this private steelmaking process are outdated and cannot perform mechanical and welding functions. When used, it may not be possible to weld with steel pipes, or the steel itself may have cracks, pores, etc. After welding, it may also leak water.

Connection is the process of fixing two pipes, fittings, or components onto a flange, with a flange pad added between the two flanges. The diameter of the pipe is small and it is low-pressure, so the flange connection cannot be seen. If in a boiler room or production site, there are flange connected pipes and components everywhere. The production billet of carbon steel flanges will undergo deformation and work hardening during cold forging, which will cause the forging die to bear high loads. Therefore, the forging die needs to be used in casting, and a hard lubricating film that avoids wear and adhesion should be selected for treatment. In addition, in order to avoid the occurrence of cracks in the billet of carbon steel flanges, it is also necessary to perform a central annealing process to advance the deformation resistance of carbon steel flanges.
