What is the pressure rating for a stainless steel vanstone flange and how is it determined?

The pressure rating for a stainless steel lap joint flange is determined by the material grade, dimensions, design standards and intended application. The pressure rating for SS lap joint flange is specified by the manufacturer or can be obtained from industry standards.

Stockist of LJ flange and lapped joint flanges in the Middle East as per EN 1092-1

Can a loose flanges be used with both small and large diameter pipes?

Loose flanges can used with large diameter pipes. They are used in applications where the pipe size exceeds the limitations of standard slip-on or weld neck flanges. Even though it is possible to use a loose flange with a smaller diameter pipe, it may require additional measures. This includes using a reducing adapter or spacer to ensure proper alignment and sealing between the flange and pipe.
