API Spec 5L

MORE DETAILS OF API 5L PIPELINE STEEL PLATE

GB/T 9711 and ISO 3183 uses same pipeline steel plate grades with API Spec 5L oil and gas pipeline steel plate, just put the x to l, the yield strength into the international system of units, expressed in MPa and to rounded to the number at the end of 0 and 5.

Manufacture of petroleum oil and gas pipeline steel plate, natural gas gathering, transmission pipeline and coal, building material slurry pipeline in the plate and strip referred to as steel plates.

In the pipeline, in addition to the requirements has a high compressive strength, but also requires a high and low temperature toughness and excellent welding performance. Oil and gas transmission pipeline steel plate API Spec 5L: (X42 L290NB, X46 , X52 L360NB, X56 , X60 L415NB, X65 L450MB , X70 L485MB, X80 L556MB). X70 used for West-East gas pipeline project pipeline API Spec 5L steel compared to the yield strength of the steel X80 which corresponds to, but the tensile strength than steel X70.
