Bending advices - Tubular HEATERS | RHK series
The thermal treatment in an annealing furnace allows to bent the tubular heater when in cold condition. It is important to consider that an already bent tubular heater cannot be bent back on the same position. Otherwise the save operation cannot be guaranteed.
The unheated zone, the length of the welded-on connecting bolts, must be arranged 10 mm in front or behind of a bending. The minimum distance between two bends is 15 mm.
U-shaped heating elements can be compressed by the manufacturer to achieve even smaller diameters. For the availability of custom-made heating elements, please don't hesitate to contact us.
