Before changing a gasket, review joint geometry, required dimensions, available bolt load, material compatibility, service conditions and assembly requirements with TEADIT. Physical tests and simulations address particular specimens, conditions and assumptions. Laboratory results do not guarantee field lifetime. The ASME paper labels Recovery Styles 1 to 3. Specimen mapping comes from the supplied TEADIT slides; exact reported values come from the paper.
