Development and commercialization of high- strength linepipe

摘要

Thinner wall thickness and/or smaller diameter can remarkably reduce the cost of pipeline construction, which has resulted in the development of high-strength linepipe. So far, X100 and X120 grades have been successfully developed and are already standardized in ISO3184, API 5L, etc. The basic properties of these pipes meet the specifications and other generally required issues. Applicability has been validated by small-scale projects.
