Previously published by API. Investigated and improved the methods of predicting cooling rates during pipeline maintenance welding. The scope of this study included (1) a review of three previous research efforts to develop satisfactory methods for welding appurtenances to in-service pipelines; (2) a survey of pipeline leak and rupture incidents associated with appurtenances; (3) the enhancement of existing analytical models for predicting cooling rates and temperatures during welding on an in-service pipeline; and (4) a validation of the thermal-analysis models that was achieved by performing welds on pipeline carrying three different liquid-petroleum products.
