Low temperature tensile properties of line pipe steels [PDF]
, 2015 Given the expected increase in Arctic oil and gas exploitation, there is a demand for high-strength line pipe steels able to cope with the Arctic climate. The state-of-the-art of the tensile properties of API 5L steels at low temperatures is reviewed and

A COMPARISON OF DIFFERENT NUMERICAL APPROACHES FOR FSW WELDS OF API 5L - X80 STEEL
Revista Mundi Engenharia, Tecnologia e Gestão (ISSN: 2525-4782), 2020 This contribution offers a study for two numerical approaches of FSW joints for the API 5L-X80 steel. The first one, a pure thermal model, takes into consideration the preponderant frictional force of the tool being in contact with the workpiece. The second model is a computational fluid dynamic approach, which involves determining experimental values ...

Energy Science &Engineering, Volume 8, Issue 1, Page 248-259, January 2020., 2020 A three‐dimensional nonlinear finite element model for burst failure simulation of corroded pipes has been established and validated by experimental data. A novel failure pressure prediction method for high‐strength line pipes has been proposed via multilayer artificial neural network technique and FEM results derived by orthogonal experimental design.

Hydrogen in Aluminium-Coated Steels Exposed to Synthetic Seawater
Surfaces, 2020 Thermally sprayed aluminium (TSA) coatings provide protection to offshore steel structures without the use of external cathodic protection (CP) systems. These coatings provide sacrificial protection in the same way as a galvanic anode, and thus hydrogen ...

Modeling of the temperature field generated by the deposition of weld bead on a steel butt joint by FEM techniques and thermographic images. [PDF]
Materials Research, 2018 The aim of this work is to predict the temperature field generated by welding a steel butt joint (API 5L X80). The prediction was modeled by finite element software Abaqus where the subroutine was developed in Fortran so that heat source motion may be ...

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
