Abstract

An apparatus for descaling pipes, essentially characterized by comprising a propellant means that uses part of the energy of a liquid that runs through the pipe to be cleaned, involving a first set consisting of at least two cutters and scrapers, followed by the driving means that goes continued in turn a second assembly that is constituted by at least two breakers, provided that the various devices and the drive element are fixed, by means of articulated joints, so that the apparatus can also travel sections in curve, the scraper cutter devices each have a series of blades arranged in a pyramidal structure and pressed against the walls of the pipe, in an elastic way by means of a system that is also elastic, consisting of a group of springs that each works on one of the blades and fixed on a sliding bushing on a central stem, and n which the blades are bolted and a spiral spring surrounding said stem and pressing on the bushing, each blade presenting a front part suitable for cutting the incrustations, according to a radial plane and a rear part in v capable of penetrating the cuts, to remove the scale, scratching at the same time the walls of the pipe, while the breaker devices have rollers with ribs, which are also pressed elastically against the walls and the assembly, so that the parts of v scratch the walls in all the circumference and the rollers break the incrustations by crushing between them and the walls, moving essentially in axial direction.
