What type of gasket should be used between the bursting disc holder and the flange, when the fluid is air and non-corrosive? How should the clamp be positioned and installed between the two flanges? Is it necessary to drill a circular hole to fix the clamp, or can it be held in place by friction against the flange surfaces?
Like flanges that use other similar materials, the gasket comes in a size that matches that of the flange; once installed, it fixes in place without the need for any holes to be made.
The gasket can be determined based on the pressure rating of the pipeline. The gripper and the gasket are about the same size, so no additional components are needed.

The flange specifications are: DN40 PN1.0MPa, with the flange standard being HG20592-2009. The seal surface type is RF. What kind of flange should be used, and what material should be used for the seal surface? Can polytetrafluoroethylene be used? Since it is said that rubber cannot be used, I’m not sure if polytetrafluoroethylene can be used
