Feature
Stainless steel coil is resistant to high temperature steam, impact corrosion and ammonia corrosion. Anti-scaling, not easy to stain, anti-oxidation corrosion; Long service life, reduce maintenance time, save costs; Good tube loading process, direct tube change, safe and reliable; The wall is uniform and the wall thickness is only 50-70% of that of copper tube, and the overall thermal conductivity is better than that of copper tube. It is the 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.
Application
Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical industry, chemical fertilizer, chemical fiber, pharmaceutical, nuclear power, etc
Stainless steel coils for fluids: beverages, beer, milk, water supply systems, medical equipment, etc
Stainless steel coil for mechanical structure: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship parts, construction and decoration.
