Low Temperature Creep Behaviour of Pipeline Steels
Canadian Metallurgical Quarterly, 2009AbstractRoom temperature creep behaviour of various grades of pipeline steels including X-52, X-70, X-80 and X-100 has been studied. Room temperature creep deformation was found to be strongly dependent on loading histories prior to creep loading. Pre-cold work generally increases the amount of room temperature creep deformation.

Contralled Rolled Steels for Offshore Pipelines
Offshore Technology Conference, 1976ABSTRACT Controlled rolled X60, X65 and X70 steels, originally developed to meet the stringent requirements of Arctic pipelining, have been used in offshore oil and gas pipelines. The technology and application of these acicular ferrite and pearlite reduced steels, which have been used successfully in several North ...

Submerged Arc Welding × 100 Pipeline Steels
Materials and Manufacturing Processes, 2014100 Pipeline Steels are welded by United States Lincoln double-wire welding machine. The welded joints have good weld formation and high welding quality, with no pore and crack inside. The tensile strength of the welded joint gets to 805 MPa, about 94.71%of that of the parent metal.

Hydrogen Induced Cracking in Pipeline Steels
Corrosion, 1983This paper describes the work conducted at the British Gas Engineering Research Station (ERS) using laboratory tests of the BP and NACE type to assess the hydrogen induced cracking (HIC) resistance of pipeline steels. Various grades of linepipe and fittings steels have been studied, and the metallurgical parameters controlling HIC resistance have been ...

Monitoring Acoustic Noise in Steel Pipelines
2008 7th International Pipeline Conference, Volume 1, 2008A system is under development to permanently monitor the acoustic noise transported in a steel pipe. Using different kinds of sensors it is attempted to identify its sources. Initial goals are detection and, if possible, prevention of severe damage to the pipeline, mainly induced by third-party interference.
