These tubes are widely used in applications requiring tight tolerances, excellent strength, and reliable performance under pressure.
Description
Cold drawn seamless tubes are high-precision steel pipes manufactured through a cold drawing process, which enhances their mechanical properties, dimensional accuracy, and surface finish. These tubes are widely used in applications requiring tight tolerances, excellent strength, and reliable performance under pressure.
Key Attributes
Cold drawn seamless tubes are produced to meet or exceed international standards such as ASTM, ASME, API, DIN, and GB. Common standards include ASTM A106, A519, DIN 2391, and GB 8163. They are available in a variety of materials including St52, C45, SS304, and more, catering to diverse industrial needs.
The outer diameter (OD) ranges from 30mm to 325mm, with wall thickness between 5mm and 30mm. Lengths can be supplied randomly from 10mm to 12,000mm, or customized as per client requirements. The ends can be beveled, plain, varnished, or fitted with plastic caps for protection.
Surface treatment often includes oiling to prevent corrosion, and the tubes are available in conditions such as annealed, normalized, quenched and tempered, or stress-relieved to suit specific operational demands.
Applications
Cold drawn seamless tubes are essential in numerous industries. They are used in automotive and motorcycle manufacturing, gas spring systems, boiler pipes, and low to medium-pressure fluid transportation pipelines. Additionally, they serve critical roles in hydraulic systems and the electric industry due to their durability and resistance to high pressure and temperature.
Packaging and Delivery
Packaging options include bundle packing, waterproof paper wrapping, sackcloth with steel straps, or heavy tri-wall boxes. The minimum order quantity (MOQ) is 3 tons, and trade terms such as FOB, CFR, CIF, EXW, and LC are accepted.
In summary, cold drawn seamless tubes offer superior quality, versatility, and reliability, making them a preferred choice for high-performance applications across various sectors.
