Forming Helical Coils
Helical coils are a specialized industrial product that are formed by bending metal tubing into a spiraling, coiled shape. To do this, metal piping is placed on a special profile bending machine that utilizes a series of rolling benders to re-form the metal from a straight orientation into a spiral one.
Depending upon the desired end-requirements and specifications of the product, a helical coil may consist of just one spiral turn or it may include a series of spirals that span several feet in length. Similarly, helical coils can be formed into a variety of sizes and from several different metals, including steel, copper, and aluminum piping, both choices depending on the need and use of the end-product.
Uses of Helical Coils
Heating and/or cooling liquid and gas is a requirement in many industrial operations, such as in the use of fossil fuels to generate electricity. But the direct heating of elements can be inefficient and sometimes dangerous, thereby making heat exchangers a big boon. Helical coils are highly effective as these needed heat exchangers due to their ability to increase the surface area of the substance being heated or cooled, and increase the rate of heat transfer.
Helical coils are used in a variety of applications, from heating crude oil in an industrial setting to heating air in the home air conditioner. These efficient units often are called upon to replace older heat exchangers due to their low maintenance and more effective performance. They're also much easier to fix and maintain when compared to other types of heat exchanging units.
