What are the characteristics of stainless steel coils?

Stainless steel industrial pipes, ultra-long coils, U-shaped pipes, pressure pipes, heat exchange pipes, fluid pipes and spiral coils are characterized by high temperature steam resistance, impact corrosion resistance and ammonia corrosion resistance; Anti-scaling, anti-fouling, anti-oxidation and corrosion; Long service life, reduced maintenance time and cost saving; Good pipe installation technology, which can be directly replaced, safe and reliable; The wall of the tube is uniform, the wall thickness is only 50-70% of that of the copper tube, and the overall thermal conductivity is better than that of the copper tube; It is an ideal heat exchange product for old unit reconstruction and new equipment manufacturing. Can be widely used in petrochemical, electric power, nuclear industry, medicine, food and other industries. Industrial stainless steel coil: heat exchanger, boiler, petroleum, chemical industry, chemical fertilizer, chemical fiber, pharmacy, nuclear power, etc. Stainless steel coil for fluid: beverage, beer, milk, water supply system, medical equipment, etc. Stainless steel coil pipe for mechanical structure: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, architectural decoration, etc. Stainless steel bright coil: welded with stainless steel strip, then thinned, from thick to thin. This process can make the wall thickness uniform and smooth, and the wall of the pipe is thinned and stretched to form a seamless effect. It is seamless to the naked eye, but its technological decision is welded pipe. The thinning process is accompanied by bright annealing, so that the internal and external walls will not form oxide layers, and the internal and external surfaces will be bright and beautiful, which is what medical products really need. The next process needs sizing, that is, the process of large stretching and small stretching to determine the outer diameter. The tolerance of the outer diameter can generally reach 0.01mm. At present, one of the most commonly used testing methods at home and abroad is to measure the friction coefficient between plastics and films and sheets based on the international standard ISO8295. China also has an equivalent national standard GB/T 10006 "Measurement Method of Friction Coefficient of Plastic Film and Sheet". The test principle of this method is to put two test surfaces flat together, make the two surfaces move relatively under a certain contact pressure, measure the required force, and get the friction coefficient according to the formula of friction force = friction coefficient × normal force.
