Cold Drawn Steel Pipe
Hengtong Petroleum Machinery — Your Trusted Cold Drawn Steel Pipe Solutions Partner
We understand that the quality of a single steel pipe is the cornerstone of the structural integrity and performance reliability of our entire equipment. Our cold-drawn steel pipes are crafted using advanced cold-drawing processes and a rigorous quality control system, transforming high-quality billets into finished pipes with exceptional dimensional accuracy, excellent mechanical properties, and a superior surface finish.
The cold-drawing process not only reduces the diameter and wall thickness of the steel pipe, but also significantly increases its strength, hardness, and toughness through cold work hardening. This means our steel pipes can withstand higher pressures, harsher environments, and more precise assembly requirements, making them ideal for your high-end applications.
Our Core Manufacturing Advantages
Superb Cold Drawing Process
We possess an industry-leading cold-drawing line capable of handling outer diameters ranging from 50mm to 500mm. Through multi-pass, high-precision drawing, we ensure dimensional consistency and uniform internal quality for each steel pipe.
Unparalleled Precision Control
Precision is the hallmark of our products. Our guaranteed ±0.05mm tolerance standard far exceeds industry standards, providing exceptional dimensional stability and interchangeability, significantly reducing the cost and time of subsequent machining and ensuring seamless assembly.
Excellent Surface Quality
The cold-drawn steel tube surface is smooth, clean, and virtually flawless. This not only reduces corrosion starting points but also provides an ideal base for subsequent electroplating, painting, or other surface treatments.
Enhanced Mechanical Properties
The cold work hardening effect gives our steel tubes higher tensile strength, yield strength, and fatigue strength while maintaining excellent ductility, achieving the perfect balance between strength and toughness.
Wide Applications
Our cold-drawn steel tubes are the material of choice for several key industries:
Hydraulic and Pneumatic Systems
Manufacturing seamless cylinder tubes, hydraulic cylinder barrels, and servo cylinder barrels requires high precision, high pressure resistance, and a superb surface finish.
Automotive Industry
Used in critical components such as shock absorbers, steering systems, drive shafts, and fuel delivery systems.
Energy Equipment
Applied to high-pressure fluid transportation, compressor components, and various energy extraction and processing equipment.
Mechanical Manufacturing and Automation
Serving as linear motion shafts, guide rods, and structural supports, they provide a solid foundation for precision machinery.
Material Handling
Suitable for conveying wear-resistant, pressure-resistant solid and fluid materials.
Abundant Material Selection
We not only offer exquisite craftsmanship, but also a diverse range of materials to meet your specific needs:
Carbon Steel and Alloy Steel
Complying with ASME, ASTM, DIN, EN, and GB standards, such as 20, 45, 4140, and 4130, they offer excellent comprehensive mechanical properties.
Stainless Steel
Including austenitic stainless steels such as 304 and 316L, as well as 2205 duplex stainless steel, they offer excellent corrosion and high-temperature resistance.
