A fashionable and authentic Polish technology is applied in the manufacturing of FAMET kind finned tubes.In this course of a smooth, thick-walled aluminium tube is slid over a core tube of any required material after which is subjected to rotary chilly rolling in order that fins are formed. Metallic for hot water heating coils should be piped fins shaping is extruded upwards by a device and progressively and uniformly thinned until screw sort fins of the required profile are formed.

This rolling process produces an exact and correct connection between the core tube and the finned outer jacket producing favourable heat move conditions. A further advantageous function is that the tight aluminium finned jacket gives full safety of the core tube against atmospheric corrosion. Because of the special design of the rolling tools the finned tubes are produced guaranteeing excessive efficiency.
