Stainless steel coil tubing heat exchanger
Description
Generally for the diameter of 0.5cm to 20mm, thickness of 0.1cm to 2.0mm coil or mosquito coil mounted bend; Widely used in chemical, machinery, electronics, power, textile, rubber, food, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields.
Species
Stainless steel industrial tube, ultra-long coil, U-shaped tube, pressure tube, heat exchange tube, fluid tube, spiral coil product features: high temperature steam resistance, impact corrosion resistance, ammonia corrosion resistance; Anti scaling, not easy to stain, anti oxidation corrosion; Long service life, reduce maintenance time, save costs; Good piping technology, can directly change the pipe, safe and reliable; Uniform tube wall, wall thickness is only 50-70% of copper tube, overall thermal conductivity is better than copper tube; 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.
Main Uses
Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical, chemical fertilizer, chemical fiber, pharmaceutical, nuclear power, etc.
Stainless steel coil for fluid: beverage, beer, milk, water supply system, medical equipment, etc.
Stainless steel coil for mechanical structure: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, construction and decoration, etc.
Stainless steel bright coil: welded by stainless steel strip and then reduce the wall, reduce the wall from thick to thin, this process can make the wall thickness uniform, smooth, and reduce the wall stretching tube wall to form the effect of no weld. According to the naked eye 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, and the inner and outer walls are bright and beautiful, which is really needed for medical products. The next process needs sizing, that is, large drawing small process, to determine the outer diameter, the tolerance of the outer diameter can generally reach plus or minus 0.01mm.
