摘要
Abstract
In combination of research results on X100 line pipe, it discussed common interested problems such as fracture control, higher yield ratio, anisotropy, defect tolerance, ductile to brittle transition, etc. The researched results showed that the ductile-brittle transition temperature and the fracture behavior of X100 steel pipe can be accurately predicted through corresponding temperature of 85%SA of DWTT test; and only full-scale burst test is a reliable method to predict fracture behavior of X100 pipeline. Therefore, at present the additional technical requirements shall be made according to the actual engineering situation, to determine the various technical indicators based on API SPEC 5L standard, such as the yield ratio, arrest toughness, DWTT and so on, to ensure the service safety of X100 line pipe.关键词
