As for iron plate welding flanges, many customers question whether the quality of iron plate welding flanges is better than forging welding flanges. In fact, the quality of iron plate welding flanges is the same as that of forged welding flanges. However, where can't the quality of iron plate welding flanges be guaranteed? That is to say, the material of iron plate welding flanges is the least guaranteed. In general, the density of iron plate welding flanges is not a problem, but in the production process, the raw material of iron plate welding flanges is rarely tested. Therefore, after production, the material of iron plate welding flanges that have not been tested cannot be guaranteed.
