Thin walled and ultra-thin seamless pipes have complex manufacturing processes and are usually formed through intermediate annealing and multiple cold rolling processes using a two roll or three roll rolling mill. In the future, the wall reduction drawing process will be further optimized to obtain smaller outer diameter sizes.

Moreover, according to the specific requirements of customers for the surface of pipes, different processes can be flexibly selected for polishing treatment.

Our company's carefully crafted precision thin-walled seamless pipes and ultra-thin seamless pipes have a series of significant advantages:
1. Ultra high dimensional accuracy, convenient cutting and processing: The product has extremely high dimensional accuracy and does not require complex secondary processing. It can be directly cut and used, greatly improving processing efficiency and reducing production costs.
2. Extremely small outer diameter tolerance: The outer diameter tolerance is strictly controlled within ± 0.05 millimeters to ensure the accuracy of the pipe when fitting with other components, effectively improving the overall assembly quality and operational stability of the equipment.
3. Accurate wall thickness tolerance: The wall thickness tolerance can reach ± 0.01 millimeters, ensuring the uniformity of the pipe wall thickness and making the pipe more stable and reliable in bearing pressure, stress, and other aspects.
4. Cold rolled surface is smooth and delicate: After precision cold rolling process treatment, the inner and outer surfaces of the pipe are extremely smooth, with a roughness of Ra0.4 μ m, providing a high-quality choice for many application scenarios that require strict surface quality.
5. Excellent inner surface quality after polishing: After special polishing process, the roughness of the inner surface of the pipe is further reduced to Ra0.1 μ m, which can effectively reduce the resistance of the medium flowing inside the pipe, improve the conveying efficiency, and meet the special needs of high-end fields.
6. Excellent pipe wall characteristics: The pipe wall is thin and evenly distributed, with good concentricity, which enhances the structural stability and reliability of the pipe while ensuring high strength.
7. Stable and excellent performance: The pipe material has stable and reliable performance, excellent corrosion resistance, and can be used for a long time in various harsh environments; Excellent pressure resistance, able to withstand high pressure without deformation or damage; Has good durability and plasticity, can adapt to different working conditions, and has a long service life.

Packing:
Considering that thin-walled and ultra-thin wall pipes are prone to deformation under external forces, the packaging process is particularly meticulous: Firstly, each pipe is covered with a specially designed plastic protective sleeve to prevent mutual scratching and wear between pipes; Subsequently, the pipes with protective covers will be uniformly packed into sturdy wooden boxes. Through scientific and reasonable packing layout and buffer filling, potential compression risks during transportation will be fully isolated, effectively ensuring the integrity and stable quality of the pipes from factory to delivery.
