Jul 01, 2017 · The stress-strain relationship of high strength X80 pipe steel used in the Second West to East Gas Pipeline is round-house type and has no plastic plateau .The elasto-plasticity of the pipe steel was described by Ramberg-Osgood model , and the eion of this relationship is as follows. (1) = E 1 + 1 + r s r where, E is initial elastic modulus; is strain; is stress, MPa
Experimental Research on Fatigue Properties of X80 X80 is the most commonly used high-grade pipeline steel in the construction of natural gas pipelines. The compatibility between high-grade pipeline steel and hydrogen directly affects safety and reliability of long-distance pipelines.
Fatigue crack growth law of API X80 pipeline steel under Loadcontrolled threepoint bending fatigue tests were conducted on API X80 pipeline steel to investigate the effects of stress ratio and specimen orientation on the fatigue crack growth behaviour. Because of the high strength and toughness of X80 steel, crack growth rate was measured and plotted versus J with stress ratio. The fatigue

Hydrogen Effects on X80 Steel Mechanical Properties X80 high strength steel is one of the advanced pipeline steels that has been applied for many years for transporting natural gas since German Mannesmann Pipe steel company first successfully developed and laid a 3.2 km test line X80 steel in 1985.
Microstructure and Mechanical Properties of Fiber Laser The results reveal that the tensile strength is higher than that of the base metal and the weld has a good impact ductility and an excellent bend performance. At the same time, the difference in microstructure between the laser zone and arc zone of laser-MAG hybrid welding of X80 pipeline steel is observed.

Separation occurring during the drop weight tear test of the standard pipeline steel grade up to API X80 and be-yond. Several X80 pipelines have been constructed since 1992. Among them, the second West-East Gas Pipeline in China is the longest one in the world . In addi-tion to the high strength, good low temperature tough-ness is also required for X80 pipeline steel because of the
The Development of X80 Steel Plate and Coil for the 2nd A parallel mainline of approximately 4950 km with 8 sub lines resulting in an overall total length of approximately 8800 km is being designed for construction in 2008. This line will be the 2 nd West-East Pipeline Project and will be built out of API X80. The major dimension of this line is 1219 mm OD × 18.4 mm wall thickness.
Jun 25, 2013 · The applications calculate the reliability of an X80 steel pipeline. By changing a single variable, the impact of the different parameters used in the model is also discussed.
