How can metallic ring gaskets be safely disassembled?

The safest method to disassemble metallic ring gaskets is by applying an axial pull. This approach ensures that the forces applied to the gasket are uniformly distributed, minimizing the risk of damaging the gasket or the flanges to which it is attached. An axial pull reduces stress concentrations and allows for the gasket to be safely removed along the axis of the flange, mitigating potential injuries or equipment damage that could result from other disassembly methods.

Using heating can distort the gasket material and introduce weaknesses or even failure, while using a torque wrench may not effectively disassemble a gasket and is primarily for tightening rather than removing gaskets. Prying the gaskets apart can lead to uneven stress distribution, possibly damaging the gasket or surrounding components. Therefore, applying an axial pull is the most effective and safest method for disassembling metallic ring gaskets.
