High Precision Steel Tube Manufacturer

We are proud to introduce ourselves as an experienced tube solution provider and reliable partner for various industrial application like hydraulic cylinder, automotive, machinery, etc.

Hydraulic Cylinder Tube

Hydraulic Cylinder tube is a kind of precision tube finally used for construction of hydraulic cylinder barrel. The key quality index is internal surface quality, including ID tolerance&ovality, internal surface roughness,etc. Others are determined by design.

Precision Tube/Mechanical Tube

Cold finished tube, covering cold drawn steel tube and cold rolled steel tube, is always considered as mechanical tubing or precision tube, due to tight or customized size&tolerance, availability of different delivery conditions, etc.

Other Steel Tube

ST37.4/SAE J524/SAE 1010

We provide additional services based on the tubes we manufacturer for our customers, including but not limited to CNC turning, hard chrome plating,galvanization, etc.

Equipment Introduction

Our equipment has high-precision internal burr removal production lines for high-frequency straight seam welded pipes such as Ф25, Ф28, Ф32, Ф50, and Ф60. It can produce round pipes with an outer diameter of Ф8 to Ф70mm and a wall thickness of 0.8mm to 3.0mm, as well as square and rectangular pipes and special-shaped pipes of various specifications. It can also customize steel pipes of various requirements according to customer needs.

Multi-Roll straightening machine

Multi-Roll straightening machine plays a critical role in precision steel tube manufacturing by ensuring straightness, enhancing quality, improving mechanical properties, and optimizing production efficiency.

Skiving and roller burnishing machine

We have two sets of skiving and roller burnishing machine.
Skiving and roller burnishing machine is vital in manufacturing precision steel tubes by providing superior surface finish, dimensional accuracy, and enhanced mechanical properties while optimizing production costs.

1. Surface Finish Enhancement:
The Skiving and Roller Burnishing Machine improves the inner surface finish of steel tubes. Skiving involves precision cutting to remove material, followed by roller burnishing, which compresses the surface, creating a smooth, polished finish. This process is critical for applications requiring low friction and high wear resistance, such as hydraulic cylinders.

2. Dimensional Accuracy:
This machine ensures tight tolerances by precisely skiving the tube's inner diameter to the desired size. Roller burnishing further refines the dimension by compressing the surface, achieving high accuracy and uniformity essential for precise engineering applications.

3. Enhanced Mechanical Properties:
Roller burnishing increases the surface hardness and fatigue strength of the steel tubes. This results in longer service life and better performance under high-pressure conditions, important for industrial and automotive uses.

4. Cost Efficiency:
Combining skiving and roller burnishing reduces the need for additional machining and polishing processes. This integration lowers production costs and improves efficiency by streamlining the manufacturing workflow.

Hydraulic cold drawing machine

Hydraulic cold drawing machine plays a crucial role in the production of precision steel tubes. We have two sets of advanced hydraulic cold drawing benches : 300 tons’ power and 250 tons’ power, here are main functions and significance:

1. Dimensional Accuracy:
The hydraulic cold drawing machine is instrumental in achieving high dimensional accuracy. During the cold drawing process, the steel tube is pulled through a die, which reduces its diameter and wall thickness to precise measurements. This results in tight tolerances and consistent dimensions, essential for applications requiring exact specifications.

2. Surface Finish Improvement:
Cold drawing significantly enhances the surface quality of the steel tubes. The process smooths out imperfections and improves the overall finish, making the tubes suitable for applications where a high-quality surface is critical, such as in hydraulic systems and automotive components.

3. Enhanced Mechanical Properties:
Cold drawing refines the grain structure of the steel, which enhances its mechanical properties. The process increases the strength and hardness of the steel tubes, making them more robust and capable of withstanding higher pressures and mechanical stresses. This is particularly important in sectors like aerospace and energy, where material performance is crucial.

4. Production of Complex Cross-Sections:
Hydraulic cold drawing machines allow for the production of steel tubes with complex and non-standard cross-sections. This capability is essential for creating custom profiles used in specialized industrial applications, such as structural components and custom machinery parts.

5. Material Efficiency:
The cold drawing process is highly material-efficient, with minimal waste. The precise control over dimensions reduces the need for extensive post-processing, such as machining, thus conserving material and reducing production costs.

6. Versatility:
Hydraulic cold drawing machines are versatile and can process various types of steel, including high-carbon and alloy steels. This flexibility makes them suitable for a wide range of industries and applications, from small diameter medical tubes to large diameter structural components.

In summary, the hydraulic cold drawing machine is essential in the precision steel tube manufacturing process for achieving high dimensional accuracy, superior surface finish, enhanced mechanical properties, and efficient production of complex cross-sections. Its ability to handle a variety of materials and produce high-quality tubes makes it indispensable in industries where precision and performance are paramount.
