Hot rolled seamless steel pipes is relative to the cold-rolled, cold rolling is below the recrystallization temperature of the rolling and hot rolled is carried out at above the recrystallization temperature of the rolling. Hot rolled seamless steel pipe can damage the refinement of the crystal grains of the steel, cast microstructure of the steel ingot and eliminate the defects of the microstructure so that the the steel organization compacting, improves the mechanical properties. This improvement is reflected in the rolling direction so that the steel is no longer at a certain extent isotropic; pouring the formation of bubbles, cracks and osteoporosis, under high pressure and temperature can also be welded together.Hot Rolled Steel Pipes (Seamless Tube) in different size, specifications, grades & thickness as per the client's requirements. The range offered by tubes is available as per the international & national standard and can be available from us at affordable prices. These pipes are used in various application industry like shipbuilding, power plants, oil and gas, automotive, sugar mills and distilleries, cement and construction industries et   Out Diameter13.7mm-914mmWall Thickness2mm-120mmLength2m-12mProducing StandardAmerican ASME B36.10M, ASTM API 5L, API 5CTJapanese JIS,German DIN,Chinese GB,BS standardSteel GradeASTM A53, A106, A210, A252, A333 etc;P.S.L.1: A, B, x42, x46, x52, x56, x60, x65, x70P.S.L.2: B, x42, x46, x52, x56, x60, x65, x70, x80JIS STPG42, G3454, G3456 etc;DIN St37, St42, St45, St52, DIN1626, DIN17175;GB 20#, Q345, 16Mn etc.Special specificationsAvailable according to customer's requirements and quantity.End ShapeBeveled end, plain end, varnished, or adding plastic caps to protect the two ends as per customer's requirementsSurface treatmentPainted, Oiled, galvanized, phosphate etcUsage1.Widely used in the mechanical treatment field, petrochemical industry, transport and construction field2.Ordinary structural purposes and mechanic structural purposes, for example in construction field, fulcrum bearing etc;3.The transportation of fluids in the projects and big equipments, for example transport of water, oil, gas etc4.Can be used in low and medium pressure boiler for the transportation of fluids, for example steam tube, big smoke tube, small smoke tube, generating tube etcThird party inspectionWelcome you to send a third party inspecting company (BV, SGS etc) to check the quality of our final products.ASTM A53 Carbon Steel Pipe & TubeASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26.  A 53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.ASTM A53 seamless steel pipe chemical composition:GradeChemical Composition (%) Max.CMnPSCuNiCrMoVA0.250.950.050.0450.400.400.400.150.08B0.301.200.050.0450.400.400.400.150.08ASTM A53 seamless steel pipe mechanical properties:GradeMechanical PropertiesTensile Strength (Mpa)Yield Strength (Mpa)A≥48,000 (≥330)≥30,000 (≥205)B≥60,000 (≥415)≥35,000 (≥240)API 5L line pipe (Seamless and welded pipe) of all grades have P.S.L.1 and P.S.L.2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc.P.S.L is the short name of product standard level. The product standard level of line pipe have P.S.L.1 and P.S.L.2, also we could say the quality standard divided in P.S.L.1 and P.S.L2. P.S.L2 is higher than P.S.L.1, not only the inspection standard is different, also the chemical property, mechanical strength standards are different. So when place the order for the API 5L line pipe, there should be stated clearly for the size, grades these general specification, also have to clarify the production standard leve, PSL1 or P.S..L2.P.S.L.2 is more strictly than P.S.L1 on the chemical properties, tensile strength, non-destructive test, and impact test.API 5L P.S.L.1 steel line pipe not required to do the impact test.For API 5L P.S.L.2 steel line pipe, except Grade X80, all the other grades of API 5L line pipe required the impact test at temperature of 0ºC.
