3/8 OD stainless steel Coil tubes, 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.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. 3/8 OD stainless steel Coil tubes for mechanical structure: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, construction and decoration, etc. 3/8 OD stainless steel Coil tubes: 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."3/8 * 0.049 * (1 ~ 2000 m) 1/8 "* 0.035 * (1 ~ 3500 m) 1/4 "* (0.035 ~ 0.049) * (1 ~ 1800 m) 1/2 "* 0.049 * (1 ~ 1000 m) Φ 3 * 0.9 * (1 ~ 3500 m) Φ 4 * 0.9 * (1 ~ 2500 m) Φ 6 * 0.9 * (1 ~ 1700 m) Φ 8 * 1 * (1 ~ 1000 m) Φ 10 * 1 * (1 ~ 8000 m) φ (10-26)★(1-2) Length (1-800m) Diameter according to customer requirements Material :201, 202, 304, 304L, 316L, 317L, 321(also customized according to user requirements) Pressure: 60-100 mpa Executive standard: ASTM A269-2002.JIS G4305 GB/T 12770-2002GB/T12771-2002 Technical requirements
