The API 5l Welded Pipe can range from 2 inches to 24 inches in outer diameter. The wall thicknesses vary with schedules and there are schedules 10 through XXS and custom sized. The API 5L PSL1 has a composition of 0.24% carbon, 1.40% manganese, 0.025% phosphorous, 0.015% sulfur, 0.45% silicon, 0.10% vanadium, 0.05% niobium, 0.04% titanium and API 5L X42-X80, PSL1&PSL2 Oil and Gas Carbon Seamless This standard covers the steel pipes made from different manufacturing process like seamless steel pipe, Electric Resistance Welded (ERW) steel pipe, Longitudinal Seam Submerged Arc Welding (LSAW) pipe and Spiral Submerged-Arc welding (SSAW) pipes. Application of API 5L X42-X80, PSL1&PSL2 Oil and Gas Carbon Seamless Steel Pipe:API 5L X42-X80 API 5L X80 ERW Pipes:TenarisConfab and Usiminas Oct 02, 2008 · For this purpose, the manufacture of electric resistance welding (ERW) pipes is recent, and it comes as an opportunity for gas pipelines, mainly onshore projects. As a function of their larger productivity, ERW pipes are more economically attractive than those produced by
Taking API 5L X80 as an example, it is mainly for manufacturing spiral submerged arc welding pipes, straight electric resistance welding pipe, longitudinally-SAW pipes and oil-gas water transmission pipes. It can also be applied to manufacturing pressured fluid transmission pipes for power stations, chemical plants and coal mines. Control of Microstructures and the Practical Properties of Jul 26, 2017 · This paper describes development of heavy-walled API X80 grade high-frequency electric resistance-welded (HFW) line pipes and conductor-casing pipes with wall thicknesses up to 20.6 mm. A fine bainiticferrite microstructure, which is preferable for low-temperature toughness, was obtained by optimizing the carbon content and applying the thermomechanical controlled hot-rolling process. Development of API X80 grade electric resistance welding Construction of high-pressure gas pipelines with API X80 grade welded large diameter pipes is progressing for the improvement of transportation efficiency.
High-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same ERW Steel Pipe, HFW Steel Pipe, Black ERW Steel Pipe, ERW ERW (Electric Resistance Welded ) Steel Pipe, HFW (High-Frequency Welding) Steel Pipe, ERW Casing. Standard:ASTM 5L, ASTM A53 B, ASTM A178, ASTM A500/501, ASTM A691, ASTM A252, ASTM A672, EN 10217 . ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. Effects of Postweld Heat-Treatment on Girth Weld Tensile Jun 13, 2018 · The girth weld tensile properties of API X80 grade high-frequency electric resistance welded (HFW) steel pipe for surface casing with the chemical composition of 0.05C1.6Mn0.06Nb (mass %) and the diameter of 558.8 mm and wall thickness of 25.4 mm were investigated by simulated postweld heat-treatment (PWHT).
