ProposalReview the existing Charpy impact absorbed energy formulas and determine if changes are needed for heavy wall materials. Simplify and refine current requirements while determining if more realistic minimums can be established; also clean-up the document. Current API 5CT requirements for Charpy impact absorbed energy allow for unreasonable and impractical requirements for very thick walls. Additionally, the text for Charpy impact requirements is fragmented and complicated which leads to potential misinterpretation. This work is to establish reasonable absorbed energy values and make the text simpler and more straightforward.
