Cold Drawn Seamless

 

Wuxi Shenlu Hydraulic Machine Parts Co., Ltd. offers premium cold drawn seamless pipes and cold drawn seamless tubing, designed for high-precision hydraulic, pneumatic, and industrial applications. Manufactured using advanced cold drawing techniques, these seamless tubes provide exceptional dimensional accuracy, smooth surface finishes, and superior mechanical properties. Our cold drawn seamless tubing is ideal for applications requiring high strength, reliability, and long-term durability. With consistent quality and robust construction, these pipes ensure optimal performance in demanding industrial environments.

 

 

 

High Precision and Accuracy – Each cold drawn seamless pipe is produced to tight tolerances (H8–H9), ensuring consistent inner and outer diameters, wall thickness, and straightness for superior performance.

Smooth Surface Finish – Cold drawing delivers polished internal and external surfaces, reducing friction, improving sealing efficiency, and extending the lifespan of the tube.

Enhanced Mechanical Strength – The cold working process increases tensile strength, hardness, and fatigue resistance, making our cold drawn seamless tubing suitable for high-pressure and heavy-duty applications.

Corrosion and Wear Resistance – Optional surface treatments, including chrome plating or anti-corrosion coatings, provide extended durability in harsh operating conditions.

Cost-Effective and Reliable – Using our seamless tubes reduces downtime and maintenance costs while ensuring dependable operation over the long term.

 

 

Our cold drawn seamless tubing is widely used in:

• Hydraulic and pneumatic cylinders
• Industrial machinery and automation systems
• Automotive and mechanical engineering
• Construction and agricultural equipment
• Aerospace and energy sectors

These seamless pipes guarantee smooth, precise, and efficient operation across a wide range of demanding industrial environments.
