Abstract

This publication applies t design of new P1 pipework when also designed in accordance with ASME B31.3 Exclusions The guidance in this publication does not apply to: Severe cyclic service Mechanical and/or thermal shock loading Hydrogen-charged service Materials outside the thickness and SMYS ranges used in this publication Any materials that are not P1 group steels Alternative Criteria The guidance in this publication is the result of a generic ECA. The method is based, amongst other things, on statistical fracture toughness correlations with the results of Charpy Impact testing according to the Master Curve approach with is the current best industry practice. This publication uses a particular set of underlying assumptions. If the results are found to be unacceptable, thenalternative routes based on specific ECA may considered. Such calculations should be based on directly measured fracture toughness data, e.g. by CTOD testing, J testing etc. These alternative criteria are in line with the principles of ASME B31P. Appendix E.
