Spirally Wound Steel Gilled Tube Heating

Gunning Gilled Tube provides the perfect all-purpose extended surface Heat Transfer medium of great strength to withstand all nominal system temperatures and pressures.


Method of Manufacture

Special purpose machines wind the strip onto the tube in a continuous spiral under considerable tension; leaving the fin of semi-flat profile and having a regular crimped contact area. Resulting in a perfect mechanical bond with excellent heat transfer from tube to fin, which will not deteriorate or loosen even in the most severe of conditions. The fin, having a crimped inner diameter offers a contact area to the tube equivalent to the outside diameter of the fin. The fins are welded to the tube at each end of the tube.

Spirally Wound Gilled Tube can be supplied in straight lengths up to 3 metres. Consideration should be given to length limitations, however, to ease transportation and site handling. At Gunning Heating, we believe that gilled tube heating provides an excellent heating solution.
