Shandong Liaocheng dry pipe industry production and finishing million light tubes, cold drawn precision steel tubes, precision drawn bright tube, inside and outside polished tubes, cold rolled precision seamless steel tubes, cold drawn seamless, full of different specifications. Dimensional tolerances table diameter size range of GB / T3639 (GB8713) DIN2391 (EN10305) of the company's normal range of special range 4mm-30mm ± 0.10mm ± 0.08mm ± 0.05mm ± 0.02mm 31mm-40mm ± 0.15mm ± 0.15mm ± 0.05 mm ± 0.03mm 41mm-50mm ± 0.20mm ± 0.20mm ± 0.05mm ± 0.03mm 51mm-60mm ± 0.25mm ± 0.25mm ± 0.08mm ± 0.03mm 61mm-70mm ± 0.30mm ± 0.30mm ± 0.10mm ± 0.05mm 71mm -160mm ± 0.30mm ± 0.30mm ± 0.10mm ± 0.05mm wall thickness tolerance of ± 0.12mm ± 0.10mm ± 0.05mm ± 0.03mm Precision Steel is a steel pipe by means of a high-precision cold drawn or hot rolling process after materials. Because precision steel outer wall no oxide layer to withstand high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening no cracks a little bit, so the main pneumatic or hydraulic components used in the production of products such as cylinders or cylinder, which can be seamless, there are welded pipe. Precise chemical composition of carbon steel pipe C, Si Si, manganese Mn, S, P P, chromium Cr. Division is specialized in the production of seamless steel pipe manufacturing enterprise, relying on cold-rolled precision seamless Φ6-Φ219mm production, after several years of development, now perennial spot sales days of steel, steel, smelting steel, Baosteel, Baotou Steel, Hengyang, Anshan Iron and Steel , Shandong and other major steel quality seamless steel pipe. Recommended quality steel line pipe products are L245, L360 line pipe, 16MnDG cryogenic tube, A33Gr6 cryogenic tube, 12Cr1MoVG alloy pipe, 15CrMoG alloy tube. The company mainly engaged in seamless steel pipe varieties are: alloy tube (mechanical processing) bright cold drawn tubes, boiler alloy pipe, seamless steel pipes with low geological pipe, line pipe, pressure vessels tube (cylinder tube, low pressure boiler tubes, high pressure boiler tube, high pressure chemical fertilizer pipe, oil cracking pipe), automobile axle casing, hydraulic prop pipe, oil pipe, precision steel pipe. Common materials are 10 #, 20 # Liaocheng bright cold drawn pipe factory, 35 #, 45 #, Q345A / B / C / D / E, 16Mn bright cold drawn pipe prices, 16MnDG, A333Gr6,20CrNiMo, 40CrNiMo, 25CrMnMo, 40CrMnMo, 15-50Mn, 15CrMoG, 12CrMoVG, 20Mn2,30Mn2,40Mn2,45Mn2.20Cr, 40Cr, 25MnCr, 30-35CrMnSiA, 12-15CrMo dry one hundred million light drawn tube plant, 20CrMo, 35 CrMo, 42CrMo, 1Cr5Mo, 27SiMn so on.
