Because of the wide range of service conditions for which ASME Code vessels are constructed and stamped, there is no economic “one size fits all” gasket style for pressure vessel and heat exchanger flanges generally larger than 24 inches in diameter that have been custom designed in accordance with the ASME Section VIII Division 1, Appendix 2 rules. Based on over 40 years of experience, the 3-ply corrugated gasket that has been designed, purchased and installed as described in this paper will be a performance-upgrade substitute for applications for which either conventional double-jacketed or spiral-wound gaskets are deemed to be suitable for the design service conditions. This is not surprising since the sealing performance operates on the same principle as that of the Kammprofile-style gasket. However, the point is made that this successful sealing performance experience was “not by gasket alone”. Because of the interactions, interdependencies and interrelationships that are inherent in a bolted joint assembly, the performance of a gasket is, as stated in PCC-1-2010, contingent upon, “many selections/activities having been made/performed within a relatively narrow band of acceptable limits.” This includes fabrication of the joint components in accordance with the purchase specifications and properly assembling the joint. Therefore, the joint screening and good practice design considerations upon which the successful experience with the 3-ply corrugated gasket has been established are reviewed in this paper.
