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.

A combined phenomenological model for the representation of anisotropic hardening behavior in high strength steel line pipes

, 2010
International audienceLine pipes have anisotropic mechanical properties, such as tensile strength, ductility and toughness. These properties depend on both prestrain during the cold forming process and on the anisotropy of the mother plates.

Influence of riboflavin on the corrosion of X80 pipeline steel by Sulfate reducing bacteria

Materials Research Express
The sulfate reducing bacteria(SRB) is commonly attached to the surface of buried pipeline steel, and the electron shuttle in the corrosion medium can promote the release of electrons from iron oxidation through the bacterial cell wall into the cytoplasm ...
