Aluminium finned tube for heat exchanger

The aluminum finned tube process is a labor-intensive process. It adopts the form of a base tube covered with an aluminum tube. (The base tube can be carbon steel or stainless steel) is extruded by a machine to form fins. The base of the fins is closely attached to the outer wall of the tube. Together, the length is from 0.5 meters to 6 meters.

It meets the demand for the length of the steel-aluminum finned tube, thus solving the trouble of re-cutting caused by improper length during use.
