Gasket Packing Q&A No. 19 Rubber Gasket
I was using a rubber sheet gasket, but there was a leak, and when I removed the gasket to take a look, I found that part of it was torn.
I was using a rubber sheet gasket, but there was a leak. When I removed the gasket to check, a part of it was torn. ■Details of the issue 〇 The rubber sheet has a low compressive strength (14.7 N/mm²), so care must be taken not to over-tighten it. 〇 If the gasket is ring-shaped or if the flange has a flat seat (in the case of RF), there is a risk of excessive surface pressure. ■Countermeasures 〇 If the flange has a full face (FF), the gasket should also be full face. 〇 If the flange has a flat seat (RF), consider whether other gaskets, such as joint sheets, can be used. 〇 Manage torque to avoid over-tightening. 〇 Set the maximum operating pressure to 1.0 MPa as a guideline.
