Ronsco - Ultra Thin Wall Seamless Tube
Thin wall & ultra thin wall seamless tube refer to the ratio of wall thickness and outer diameter less than 6% seamless tube. They are generally formed by intermediate annealing and multi-pass cold rolling of two or three high mills. Small outer diameter can be obtained by reducing the wall drawing process. According to customer`s special surface requirements, the tubes can be polished by different processes.
Our company`s precision thin wall seamless tube and ultra thin wall seamless tube mainly has the following characteristics:
- High dimensional accuracy, free cutting.
- OD tolerance can reach±0.05mm
- WT tolerance can reach ±0.01mm
- Smooth surface, precision cold rolling internal and external surface roughness can reach Ra0.4μm.
- Smooth surface, after different polishing process, the internal roughness can reach Ra0.1μm.
- The tube wall is thin and uniform with good concentricity.
- Out of roundness: within 0.3mm for OD6~25mm, within 0.5mm for OD26~57mm, within 1.0mm for OD58~105mm.
- Stable performance, excellent corrosion resistance, pressure resistance, durable strength and plasticity.

Because thin-walled and extremely thin-walled tubes are easy to deform under the action of external forces, they are generally packaged with plastic covers to avoid scratches between tubes, and then packed in wooden cases to protect the tubes from being squeezed and deformed during the whole transportation process.
- Suitable for precision seamless steel pipe with special dimensional accurancy and high surface quality, such as precision mechanical structure, hydraulic equipment and parts manufacturing.
- It is widely used in medical, food, aviation, aerospace, electric power, chemical, electronics, electrical, optical, textile, shipbuilding, automobile and other industries.
- Specific applications include semiconductor, sensor housing, level gauge, auto parts, instrumentation, pneumatic components, corrugated metal hose, printer, copier, oil tube, gas tube, water tube and so on.
