Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 Long‐distance pipelines are threatened by a variety of natural geological hazards. A stress monitoring system driven by the strain‐stress solution algorithm was proposed; it can achieve real‐time maximum axial stress measurement by installing vibrating wire gauges (VWGs) on the surface of the pipe.

Thermodynamic analysis of X80 pipeline steel after calcium treatment [PDF]
Proceedings of the 2015 2nd International Conference on Machinery, Materials Engineering, Chemical Engineering and Biotechnology, 2016 Based on thermodynamic calculation, analysis the inclusions and thermodynamics of X80 before and after calcium treatment on the sample of a steel production.Results show that the effect of Al2O3 inclusions degeneration is good and S would exist in a dissolved state so that avoids the CaS inclusion precipitation when the ω(Als) is 0.04%,ω(O) is adjusted

Study on Stress‐Strain Characteristics of Pipeline‐Soil Interaction under Ground Collapse Condition
Geofluids, Volume 2022, Issue 1, 2022., 2022 Ground collapse is one of the main geological disasters affecting the safe operation of oil and gas pipelines. Studying the stress‐strain characteristics of pipe‐soil interaction under ground collapse has an important guiding role for the prevention of ground collapse and the safety protection of pipelines.

The influence of material anisotropy and spiral welding on tensile strain capacity of spiral welded pipes [PDF]
, 2015 The longitudinal strain capacity of spiral welded pipelines displays to some extents unexplained behaviour. Therefore, they are not (yet) used extensively in offshore applications and harsh conditions, demanding a strain based design. An important factor
