API SPEC SL GB/T9711 GB/T14164 |
It is mainly used for making spiral submerged arc welded pipe, electric resistance welding and longitudinal submerged arc welding pipes to lay pipeline of oil, gas and water. II can be popularized and applied in power station, chemical plant, coal, ore and other pressure fluid conveying pipes, as well as the manufac- lure of engineering structural parts. According to the specific pipeline project, service condi- lions, and pipeline manufacture method, the supplier and the buyer need to sign a technical agreement. |
Oil-and-gas Pipeline Steel
Oil-and-gas Pipeline Steel not only has high strength, but also has good low temperature toughness, high impact value, little anisotropy of mechanical properties, and the comprehensive quality meets the requirements of general international standard API 5L. The products have perfect molding and welding performance, and have excellent resistance to cold cracking and hot cracking, small fatigue crack growth rate and stress corrosion tendency if compared with the same kind of imported steel. The single coil is heavy, and is suitable for mechanized continuous production and has high utilization rate of materials.
The products can be divided into A, B, X42, X46, X52, X56, X60, X65, X70, X80, X100 (API 5L standard) according to the intensity level; it can be divided into ferrite + pearlite, pearlite + acicular ferrite and low carbon bainite according to the metallographic type; it can be divided into hydrogen sulfide resista, high strength, high toughness and spiral submerged arc welding pipe (SSAW), electric resistance welding (ERW) and longitudinal submerged arc welding (LSAW) according to its properties; it can be divided into high cold zone, acid medium, seabed, gas transmission, oil transportation and so on according to its usage. Users can select the corresponding type of pipeline steel products with different properties and usage according to their different demands.
