This Tri-clamp connection is designed to comply with ASME B31.3-2008. It is an unlisted component because of its shape, hence the ASME VIII-1 Appendix-24 (24-1(b)) cannot be used to validate it. Two options remain for determining the MAWP:1. A burst test per UG-101(m)2. Finite Element Analysis (FEA) per ASME VIII-2, Part 5 The Tri-Clamp can be qualified using Option 2 under ASME B31.3 304.7.2(d). Allowable stress should be taken from
