Residual Strength Evaluation of Corroded Pipeline Based on Effective Area Method
摘要
Abstract
The residual strength evaluation of corroded pipeline carried out regularly was significant for guiding pipeline maintenance and operation safety.Effective Area Method, an important residual strength evaluation technique, was studied.A corrosion defect measure method was proposed, which was suitable for the Effective Area Method.The computer program was compiled according to the calculation model of Effective Area Method.The residual strength of an actual pipeline defect was evaluated by the Effective Area Method and Modified B31G respectively.The result showed that the Effective Area Method was less conservative than Modified B31G.关键词
