Stainless steel coiling tubing

Stainless steel coil, in English, is generally a coil or mosquito repellent incense elbow with a diameter of 0.5cm to 20mm and a thickness of 0.1cm to 2.0mm; It is widely used in chemical industry, machinery, electronics, electric power, textile, rubber, food, medical equipment, aviation, aerospace, communication, petroleum and other industrial fields.

Types of stainless steel coils：

Stainless steel industrial pipe, super long coil, U-shaped pipe, pressure pipe, heat exchange pipe, fluid pipe and spiral coil. Product features: high temperature steam resistance, impact corrosion resistance and ammonia corrosion resistance; Anti scaling, not easy to stain, anti-oxidation and corrosion; Long service life, reduce maintenance time and save costs; Good tube installation technology, direct tube replacement, safe and reliable; The wall of the pipe is uniform and the wall thickness is only 50-70% of that of copper pipe, and the overall thermal conductivity is better than that of copper pipe; It is an ideal heat exchange product for the transformation of old units and the manufacture of new equipment. It can be widely used in petrochemical, electric power, nuclear industry, medicine, food and other industries.

Purpose of stainless steel coil：

1. Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical industry, chemical fertilizer, chemical fiber, pharmaceutical, nuclear power, etc.

2. Stainless steel coil for fluid: beverage, beer, milk, water supply system, medical equipment, etc.

3. Stainless steel coil for mechanical structure: printing and dyeing, printing, textile machinery, medical instruments, kitchen equipment, automobile and ship accessories, architecture and decoration, etc.

4. Stainless steel bright coil: the stainless steel strip is welded and then the wall is reduced from thick to thin. This process can make the wall thickness uniform and smooth, and the reduced wall stretches the pipe wall to form the effect of no weld. According to the naked eye, it is seamless pipe, but its process decision is welded pipe. The process of wall reduction is accompanied by bright annealing, so that the inner and outer walls will not form oxide layer, the inner and outer walls are bright and beautiful, This is really what medical products need. The next process requires sizing, i.e. large drawing and small process to determine the outer diameter. The outer diameter tolerance can generally reach plus or minus 0.01mm.
