Product Description:Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) ,SSAW STEEL PIPEis an important welding method. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of pressure vessel, pipe section, box beam and column and other important steel structures.  In recent years, although many new welding methods with high efficiency and high quality have appeared successively, the application field of submerged arc welding has not been affected.  From the perspective of the share of the weight of the deposited metal in various fusion welding methods, submerged arc welding accounts for about 10%, and it has not changed much over the years.  Specification:SSAW Steel Pipe(Spiral Submerged Arc Pipe)Sizes:Out diameter:219mm-3620mmWall thickness: 5mm-25.4mmLength: 1m-48mStandard and Classification of SSAW Steel PipeClassificationStandardMain ProductsLine PipeAPI 5L PSL1/2Line pipe         CasingAPI 5CT/    ISO 11960 PSL1Steel pipe for use as casing or tubing for wells of petroleum and natural gas industriesSteel Pipe for Fluid ServiceASTM A53Black and hot-hipped galvanized welded and seamless steel pipeBS EN10217-2Welded steel tubes for pressure purposes - delivery technical conditions - part2: Electric welded non- alloy and alloy steel tubes with specified elevated temperature propertiesBS EN10217-5Welded steel tubes for pressure purposes - delivery technical conditions - part5: submerged arc welded non-alloy and alloy steel tubes with specified elevated temperature propertiesSteel Pipe for Ordinary StructureASTM A252Welded and seamless steel pipe pilesBS EN10219-1Cold formed welded structural hollow sections of non-alloy and fine grain steels - part1: Technical delivery conditionsBS EN10219-2Cold formed welded structural hollow sections of non-alloy and fine grain steels - part2: tolerances dimemsions and sectional propertiesChemical Analysis and Mechanical Properties of SSAW Steel PipeStandardGradeChemical Composition(max)%Mechanical Properties(min)CSiMnPSTensile Strength(Mpa)Yield Strength(Mpa)API 5CTh40----0.030417417J55----0.030517517K55----0.300655655API 5L PSL1A0.22-0.900.0300.030335335B0.26-1.200.0300.030415415X420.26-1.300.0300.030415415X460.26-1.400.0300.030435435X520.26-1.400.0300.030460460X560.26-1.400.0300.030490490X600.26-1.400.0300.030520520X650.26-1.450.0300.030535535X700.26-1.650.0300.030570570API 5L PSL2B0.220.451.200.0250.015415415X420.220.451.300.0250.015415415X460.220.451.400.0250.015435435X520.220.451.400.0250.015460460X560.220.451.400.0250.015490490X600.120.451.600.0250.015520520X650.120.451.600.0250.015535535X700.120.451.700.0250.015570570X800.120.451.850.0250.015625625ASTM A53A0.250.100.950.0500.045330330B0.300.101.200.0500.045415415ASTM A2521---0.050-3453452---0.050-4144143---0.050-455455EN10217-1P195TR10.130.350.700.0250.020320320P195TR20.130.350.700.0250.020320320P235TR10.160.351.200.0250.020360360P235TR20.160.351.200.0250.020360360P265TR10.200.401.400.0250.020410410P265TR20.200.401.400.0250.020410410EN10217-2P195GH0.130.350.700.0250.020320320P235GH0.160.351.200.0250.020360360P265GH0.200.401.400.0250.020410410EN10217-5P235GH0.160.351.200.0250.020360360P265GH0.200.401.400.0250.020410410EN10219-1S235JRH0.17-1.400.0400.040360360S275JOH0.20-1.500.0350.035410410S275J2H0.20-1.500.0300.030410410S355JOH0.220.551.600.0350.035470470S355J2H0.220.551.600.0300.030470470S355K2H0.220.551.600.0300.030470470Latest SSAW project order:SSAW Pipe Manufacturing Process:Whole Services:About us:1.Pipe:Permanent Steel Manufacturing Co.,Ltd has been committed to being a major supplier of quality kinds of carbon steel pipe, stainless steel tube, hollow section numerous types of piping equipments including Bend, Cap, Coupling, Elbow, Reducer, Stub End, Tee, Olet, Joint, Gasket, etc. The Products from Permanent Steel Manufacturing Co.,Ltd are supplied in accordance with appropriate International Standards as well as Customer Specifications in a large variety of steel grades and dimensions. Permanent Steel Manufacturing Co.,Ltd on a 250,000 m2 area and has three production units: Foundry, Rolling and Extrusion mills.
