Finned tube
A finned tube is a tubular component that has fins made of a material that conducts heat well to improve the heat or cooling capacity that can be transferred. The ribs are used to enlarge the pipe surface and can be produced on the outside, for example, by rolling (similar to thread rolling), by soldering or welding, by pressing or grooving into the pipe wall. The ribs on the inside of the pipe can also be rolled or drawn. It is also possible to incorporate pressed or sheet metal profiles on the inside .
There are a large number of design variants. The ribs can be on the outside of the pipe and / or on the inside of the pipe. Areas of application are in heating technology, refrigeration and air conditioning technology, in apparatus and plant construction and in the automotive industry. The materials used are aluminum , stainless steels , copper and copper alloys, polypropylene , steel , titanium and nickel-based materials.
If a high level of operational safety is required (for example with aggressive media), special double-walled pipes are used, with a leak indicator device if required.
