Cold Drawn Seamless Tube from Threeway Steel Co., Ltd. is manufactured by drawing hot-rolled seamless mother pipes through a die at room temperature, resulting in tighter tolerances and a smoother surface finish. The process enhances mechanical properties, making these tubes ideal for precision applications such as hydraulic cylinders, automotive drive shafts, and bearing races. The supplier specifies material options including carbon steel (SAE 1018, 1026) and alloy steel (4140), catering to a range of strength and durability requirements.
The tubes meet industry standards such as ASTM A519, DIN 2391, and EN 10305, ensuring they are suitable for mechanical and hydraulic systems where dimensional accuracy is critical. Typical outer diameters range from 10 mm to 150 mm, with wall thicknesses between 1.5 mm and 20 mm, depending on the application. The cold drawing process also improves the tube’s straightness, with tolerances often as tight as 0.5 mm per meter for high-precision uses.
Industries such as heat-exchanger manufacturing, automotive, and bearing production rely on these tubes for their superior surface quality and consistent performance. The supplier highlights that cold drawn seamless tubes reduce machining time and improve material utilization, making them a cost-effective choice for bulk buyers. Packaging is typically in hexagonal bundles with protective coatings to prevent corrosion during transit, and buyers should confirm Incoterms such as FOB Shanghai or CIF.

Before placing an order, confirm the exact material grade and dimensional specifications to ensure they align with your project’s requirements. Verify compliance with standards such as ASTM A519 or EN 10305, as these are essential for hydraulic and mechanical applications. Request material test reports and third-party inspection certificates to validate the tubes’ quality and traceability.
For logistics, discuss Incoterms such as FOB Shanghai or CIF with the supplier to clarify responsibilities for shipping, insurance, and customs clearance. Confirm packaging details, as these tubes are typically bundled in hexagonal packs with protective coatings to prevent damage during transit. Lead times may vary based on production schedules, so align delivery timelines with your project needs.
Upon receipt, conduct visual and dimensional inspections to verify the surface finish and straightness of the tubes. Perform hydrostatic or non-destructive tests if your application demands it. Ensure all documentation, including certificates of compliance and test reports, is complete and accurate for your records.
