摘要
介绍了我国西气东输二线X80钢级管线钢管的应用以及我国对X90、X100、X120钢级管线钢管的开发进展情况。指出我国近年来在高强度和超高强度管线钢管研究开发方面取得了显著进展,但是在X100钢级管线钢管的适用性研究方面与国际先进水平还存在一定的差距。
Elaborated in the paper are the application of the X80 linepipes to Line No.2 of the West-East Natural Gas Transmission Project,and the recent progress of the R D of the linepipes in Steel Grades X90,X100 and X120. It is recognized that great progresses have been achieved in the R D of hi-strength and extra-hi-strength steel linepipes over the resent years. Nevertheless,to a certain degree,the domestic research on suitability of the X100 steel linepipe is still lapping behind the international level.
