Pliable ducting manufacured by winding strip steel, aluminium or other malleable maerials together in various combinations. Basically, one, two or three layers of strip are spirally wound round a cylindrical mandrel with an overlap of each layer. Convolutions are then rolled into packed layers proving strength but, at the same time, permitting bending without bore distortion.
Construction: inner and outer layer of bitumen paper interleaved with single layer of aluminium, external colour: black kraft paper, temperature upto 100 °C.
