<p>The element has a support (1) extending along a longitudinal axis (L) and possessing dimensions to allow insertion of the element into a conduit. Cleaning units (5) are fixed on the support, where the units remove deposits covering an interior wall of the conduit by mechanical action. The units are flexible, and include a fixing end (7) and a free end (8). The fixing end is fixed on the support, and the free end is elastically stressed on the deposits/on the wall. Each cleaning unit has a coil (11) in vicinity of the fixing end, where the coil possesses elastic deformation properties.</p> |
