Helical tube coils are manufactured through a process that involves bending straight tubes into a helical shape using specialized coiling machinery. This typically starts with selecting an appropriate material, usually metal such as stainless steel or copper, which is cut to the desired length. The tube is then fed into a coiling machine, where it is wound around a mandrel or spindle to form the helical shape. The coiling process may involve the application of heat to make the metal more pliable and reduce the risk of cracking. Once the helical shape is achieved, the coils undergo various finishing processes such as annealing (heat treatment to relieve internal stresses), cleaning, and sometimes coating to enhance corrosion resistance. The final product is a helical tube coil used in applications like heat exchangers, refrigeration systems, and fluid transfer systems, where efficient heat transfer and compact design are crucial.
