Copper finned tubes manufacturing process Pipe line——compressing or rolling——strip peeling——washing——pressure test——blast blowing——packaging. The cold machining process of fins provides excellent mechanical resistance , fins are strong and have strong resistance to atmospheric corrosion, etc. The pressure required to extrude the fin from the aluminum sleeve creates an excellent “pressure bond” between the two materials. In addition, the aluminum finned material completely surrounds the metal of the tube, so there is no risk of electrical corrosion at the fin root (between the tube and the fin). All of these advantages ensure the most stable performance over time of all other fin types. Copper finned tube applications Copper finned tubes products are widely used in petrochemical, power plant and power plant renovation, air conditioning and refrigeration, boilers, finned tube economizers and air preheaters.

U bend tube applications In various bends, various bends are inevitably used, such as marine pipelines, automobile oil pipes and other pipelines. Compared with other types of elbows, the arc elbow has many advantages. First, all kinds of materials flow smoothly at the arc elbow, and the impact force on the pipe wall is small and uniform; secondly, the arc elbow itself has less stress concentration. Strong and high impact resistance; With the rise of modern steel furniture, office chairs, beach chairs, luggage carts, shopping carts, children’s trolleys, cribs, computer tables, etc., several metal tubes form several bright lines, which are practical, convenient, safe and reliable ; Air conditioning refrigeration pipes mainly include elbows, small U-shaped pipes, return elbows, etc.; The bathroom industry now has more and more bends, faucets, towel racks and S-shaped accessories. Motorcycles, automobiles, electric vehicles, bicycles and other vehicles, handlebars, bumpers, frames, etc.; Fitness equipment, lighting, construction machinery and other industries.

coil tube Stainless steel coil applications Stainless steel coils are widely used in chemical, machinery, electronics, electric power, textiles, rubber, food, medical equipment, aviation, aerospace, communications, petroleum and other industrial fields. Industrial stainless steel coils: heat exchangers, boilers, petroleum, chemicals, fertilizers, chemical fibers, pharmaceuticals, nuclear power, etc. Stainless steel coils for fluids: beverages, beer, milk, water supply systems, medical equipment, etc. Stainless steel coils for mechanical structures: printing and dyeing, printing, textile machinery, medical equipment, kitchen equipment, automobile and ship accessories, construction and decoration, etc. Bright stainless steel coil: welded with stainless steel strips, then reduce the wall, reducing the wall thickness from thick to thin. This process can make the wall thickness uniform and smooth, and the reduced-wall stretched tube wall forms a weld-free effect. According to the naked eye, it is a seamless pipe, but its process is determined to be a welded pipe. The process of wall reduction is accompanied by bright annealing, so that the inner and outer walls will not form an oxide layer, and the inner and outer walls are bright and beautiful, which is really needed for medical products. The next process requires sizing, that is, the process of large and small drawing, to determine the outer diameter, the outer diameter tolerance can generally reach plus or minus 0.01mm.
