3 Terms, Definitions, and Acronyms 3.1 Terms and Definitions For the purposes of this RP, the following definitions apply: 3.1.1 ASME code ASME Boiler and Pressure Vessel Code, Section VIII, Division 1. 3.1.2 final PWHT The last post-weld heat treatment after fabrication of the vessel and prior to placing the vessel in service. 3.1.3 fine grain practice A steelmaking practice where aluminum or other elements are added to the steel to provide resistance to grain growth during heat treatments. The steps and/or testing to achieve fine grain practice are defined in the ASME specifications for materials (e.g. ASME SA-20, paragraph 8). 3.1.4 hot forming Mechanical forming of vessel components above the final PWHT temperature. 3.1.5 Larson-Miller Parameter (LMP) Formula for evaluating heat treatments: LMP = T × (20 + logt) where T is the temperature in °Kelvin; t is time in hours. 3.1.6 maximum PWHT Specified heat treatment of test specimens used to simulate all fabrication heat treatments including austenitizing, tempering, the final PWHT, a PWHT cycle for possible shop repairs, and a minimum of one extra PWHT for future use by the owner. NOTE To determine the equivalent time at one temperature (within the PWHT range), the Larson-Miller Parameter formula may be used; results to be agreed upon by Purchaser and fabricator. 3.1.7 minimum PWHT Specified heat treatment of test specimens used to simulate the minimum heat treatments (austenitizing, tempering and one PWHT cycle). NOTE To determine the equivalent time at one temperature (within the PWHT range), the Larson-Miller Parameter may be used; results to be agreed upon by Purchaser and fabricator.
