Flat welding flange refers to a kind of flange that is linked to a container or pipeline the usage of a fillet weld. It belongs to any kind of flange. During design, based totally on the integrity of the connection between the flange ring and the straight tube section, it shall be checked as both an essential or unfastened flange. There are two sorts of flange rings: with and except a neck. Compared with the neck welded flange, the flat welded flange has a easy shape and saves materials, however its stiffness and sealing are no longer as true as the neck welded flange.

As for iron plate welding flanges, many customers are questioning whether the quality of iron plate welding flanges is better than forged welding flanges. In fact, the quality of iron plate welding flanges is the same as that of forged welding flanges. However, where is the material of iron plate welding flanges that cannot be guaranteed? This means that the material of iron plate welding flanges is the least guaranteed, because in general, the density of iron plate welding flanges is not an issue.

The flat flange has sufficient strength and must not deform during the tightening process. The sealing surface of the flange should be smooth and clean. When installing stainless steel flanges, oil stains and rust spots should be carefully cleaned. Gaskets shall have good oil resistance and aging resistance, as well as relatively good elasticity and mechanical strength.

Advantages of high neck flanges The high neck flange, due to its overall shape and high neck height, greatly improves the stiffness and load-bearing capacity of the flange. Suitable for assembly lines and automated production, the production efficiency of component assembly and welding processes has been greatly improved. The insertion form of relatively flat flange and steel pipe reduces the consumption of welding materials, greatly reduces the welding workload and Labor burden, reduces the welding stress, and the structure is not easy to deform.
