摘要：

Commercial scale trials of X100 for Artic gas transmission pipelines have been conducted at IPSCO. Different alloying systems and thermo-mechanical controlled processes have been employed to make X 100 coils. The coils were made into spirally welded pipes at IPSCO Spiral Mill in Regina, Canada. These pipes were tested in different conditions, namely as-welded, after hydro-testing, and after thermal coating. Therefore, the effects of as-supplied material and pipe-making processes on the final mechanical properties of pipe were evaluated. It was found that the tensile specimen size and sampling location had a noticeable effect on the testing results. The difference was also observed between the flattened strap specimen and round bar. The influence of the anisotropy of the as-supplied coils and the thermal coating on the final pipe properties will also be presented.
