34mm 38mm Cold Drawn Seamless Tube Cold Rolled Seamless Steel Pipe SCH20 SCH30

ASTM A53 ASTM A106 SCH20 SCH30 Cold Drawn CDS Tube

Cold drawn seamless steel tube, also known as CDS tube, refers to a type of seamless steel tube that is produced using a cold drawing process. This process involves pulling a solid steel bar or billet through a die to reduce its diameter and achieve the desired dimensions and surface finish.

Specifications

Features of cold drawn seamless steel tubes:

1. Seamless Construction: Cold drawn seamless steel tubes are manufactured using a seamless process, meaning they do not have any welded joints along their length. This seamless construction ensures a uniform and continuous structure, eliminating the risk of weak points or potential leakage.

2. Cold Drawing Process: The cold drawing process involves pulling a solid steel bar or billet through a die at room temperature. This process reduces the outer diameter and wall thickness of the steel, while improving the surface finish and dimensional accuracy. The cold drawing process also enhances the mechanical properties of the steel tube, including its tensile strength and hardness.

3. Excellent Dimensional Accuracy: Cold drawn seamless steel tubes are known for their precise dimensional tolerances. The cold drawing process allows for tight control over the outer diameter, inner diameter, and wall thickness of the tube, resulting in consistent and accurate dimensions. This dimensional accuracy ensures proper fitment with fittings, connectors, and components in various applications.

4. Smooth Surface Finish: Cold drawn seamless steel tubes have a smooth surface finish, which is achieved through the cold drawing process. The surface is free from scale, oxides, and other imperfections, reducing friction and turbulence within the tube and facilitating efficient fluid flow in hydraulic or other applications.

5. High Strength and Integrity: Cold drawn seamless steel tubes exhibit excellent mechanical properties, including high tensile strength and toughness. The cold drawing process aligns the grain structure of the steel, resulting in improved strength and integrity. This makes cold drawn seamless steel tubes suitable for high-pressure and high-stress applications.

6. Wide Range of Applications: Cold drawn seamless steel tubes find applications in various industries, including automotive, machinery, hydraulic systems, precision engineering, and oil and gas. They are used in components such as hydraulic cylinders, shock absorbers, precision tubes, bearings, and other critical parts that require precise dimensions, strength, and reliability.

7. Corrosion Resistance: The corrosion resistance of cold drawn seamless steel tubes depends on the specific steel alloy used. Carbon steel tubes may require additional coatings or treatments to enhance their corrosion resistance. Alternatively, stainless steel or alloy steel tubes can be used to provide better resistance to corrosion in demanding environments.

8. Cost-Effective: Cold drawn seamless steel tubes offer a cost-effective solution for many applications. They provide excellent strength and dimensional accuracy without the added cost of welding or additional fabrication processes.
