Release time:
Mar 07,2024
Non-standard flange is a kind of flange relative to the national standard or some foreign standards. Because the standard flange cannot meet the requirements of use in some special occasions, it is necessary to reform and improve some standard flanges. Non-standard flanges are produced, and there are also requirements when designing non-standard flanges. From a design point of view.

From the design point of view, the flange can be divided into three types: it is a loose flange, that is, the flange is not directly fixed on the shell or although it is fixed, it cannot guarantee that the flange is on the shell as a whole to bear the bolt load. It is an integral flange, that is, the flange is forged or cast into one body in the shell, or the welding flange is used to become one body in the shell.
It is an arbitrary flange. From the structural point of view, the French is integrated with the shell, and the rigidity is worse than the integral flange. No matter what kind of flange, its design strength calculation method can include two basic problems: First, each part of the flange connection structure must have sufficient strength. Second, the connection itself must be sealed.
