Formation and evolution of inclusions in the refining process of X80 pipeline steel

工程科学学报, 2023
To further meet the requirements for using pipeline steel in extreme environments and to improve its safety in service, the inclusion control level in pipeline steel urgently needs improvement. In this paper, the variation laws of inclusion type, size, and composition in the refining process of X80 pipeline steel were studied through industrial trial ...

Research on Strain of Unequal Wall Thickness Pipeline of the X80 Pipeline under Lateral Load

Journal of Physics: Conference Series
Abstract X80 steel is a material with high strength and good toughness, which is widely used in long-distance natural gas pipelines. Pipelines will have different wall thicknesses, depending on the safety level requirements of different regions.

Relationship between coercive force and stress of X80 pipeline steel

Journal of Physics: Conference Series
Abstract X80 pipeline steel is widely used in long-distance oil and gas transportation due to its high strength and toughness. However, reducing wall thickness to cut costs can lead to stress concentration during forming and under external loads.
