| Abstract: | This article briefly introduces grade X80 pipeline projects in the world which have been built，and emphasizes production process and physical chemical properties indexes of grade X80 pipeline steel pipe of Nippon Co.Japan, and also conducts simulation calculation to ductile fracture spreading of grade X80 gas transmission pipeline according to alternative design scheme of China second west to east gas pipeline project.Calculation results shows that requirement of alternative design scheme of the second west to east gas pipeline project is stricter with crack arrest property. |
