STAINLESS STEEL

COIL TUBES

Bnjis produce and manufacture a wide range of stainless steel coil tubes. Stainless steel coil tubes refer to those tubes with diameter ranging from 0.5mm to 20mm and wall thickness from 0.1mm to 2.0mm, for instance, pancake coil tube is such a kind. Stainless steel coil tubes are applied extensively in petrochemical industry, machinery, electronics, electric power, textile, rubber, food, medical devices, aeronautics, aerospace, communication, petroleum and other industries. The process of bright stainless steel coil tube involves welding stainless steel strips and reducing wall thickness.

With the wall thickness becoming thinner, this process uniforms and smoothens the wall thickness. Meanwhile, the drawing process for reducing pipe wall thickness gives the seamless appearance. As this process involves bright annealing, it frees the internal and external tube wall from shaping oxide coating. These tubes, bright and beautiful from both inside and outside, are exactly what medical devices need. The SS coiled tubes are available in length at 150meters per coil for the seamless tube and 1500meters per coil for the welded tube. Kindly note, length can be customized as per your special requirement.

FEATURES

Stainless steel coil tube boasts many good features as below:
1) resistance to high-temperature steam, impingement corrosion and ammonia corrosion;
2) anti-scaling, hardness to get stained, corrosion resistance to oxidation;
3) long service life, reduced maintenance time, cost saving;
4) excellent tabulation, readiness for tube change, safety and reliability;
5) uniform tube wall, 30%-50% less than the wall thickness of copper tube, superior overall thermal conductivity coefficient;
6) ideal heat exchange product for upgrading old sets and manufacturing new equipment.
