Cold drawn precision tube from Shandong Jialong Petroleum Pipe Manufacture Co., Ltd. is manufactured to standards including GB/T 3639, DIN 2391, EN 10305, and JIS G 3473. The outer diameter ranges from 8 mm to 300 mm, with wall thicknesses between 1 mm and 20 mm. Dimensional tolerances are held at ±0.1 mm to ±0.2 mm for both outer diameter and wall thickness, ensuring consistency for high-precision applications. The material grades available include ASTM A106B, ST44, CK45, Q345B, 40Mn4, SMN420, 30Mn5, 36Mn5, 20Cr4, 1Cr4, 15CrMo5, 20CrMo5, 25CrMo4, and 42CrMo4, selected for mechanical strength and machinability.
These tubes are produced through cold drawing and cold rolling processes, which enhance surface finish and dimensional accuracy beyond hot-rolled alternatives. The material composition is engineered for high tensile strength and low elongation under load, making them suitable for hydraulic, pneumatic, and structural applications. Surface roughness typically falls below Ra 0.8 µm, and internal honing is standard for bore-critical uses. These are not general-purpose tubes but engineered components requiring precise geometry and material consistency.
Buyers in industrial automation, oil and gas equipment, and heavy machinery sectors source these tubes for cylinder barrels, piston rods, and high-pressure fluid conduits. The minimum order quantity is 5 metric tons per size and grade. Packaging is in standard seaworthy bundles with anti-rust coating and wooden crating. Delivery is FOB Qingdao or Lianyungang. Buyers should confirm heat treatment status and material certification for each batch, as this affects performance in stress-critical environments.

Before ordering, verify the exact material grade, heat treatment condition, and dimensional tolerances against your application requirements. Request a sample with full material test report, including chemical analysis and mechanical properties. Confirm that the tube surface is free of laps, seams, or scale, and that internal bore meets roughness specifications. Do not accept tubes without batch traceability to the furnace melt number.
Lead time typically ranges from 25 to 45 days after order confirmation, depending on grade and quantity. Incoterms are usually FOB Qingdao or Lianyungang. Payment terms are commonly 30% advance, 70% against copy of bill of lading. Buyers should confirm whether packaging includes moisture barriers and anti-rust film, and request container loading photos prior to shipment.
Inspection should include dimensional checks with calibrated gauges, surface defect inspection under UV light, and hydrostatic pressure testing at 2.5x operating pressure. Request a certificate of conformity per EN 10204 3.1. For critical uses, consider third-party inspection at the factory. Retain one sample per batch for future reference, especially if the tubes will be welded or machined.
