ABSTRACT:
A tube cleaning material for cleaning the inside of a tube is adapted to be passed through such a tube by means of a back pressure. The tube cleaning material includes a cylindrical body provided with at least one, and, preferably, a plurality of spiral grooves formed in its peripheral surface. The grooves extend and run in the same direction from the front to the rear of the cylindrical body. The edges of the groove are brought close to each other, when the material is pressed into the tube, so as to prevent wrinkles from appearing on the surface of the material. In addition, the grooves allow the back pressure creating medium to go ahead of the body to moisten the sticking contaminants on the tube. This facilitates the removal of contaminants especially when the medium is water. The body is rendered rotatable by the fluid medium. In one embodiment of the invention the grooves of one side communicate with the grooves on the other side of the body by a bore diametrically extending through the body. This facilitates the attaching of an auxiliary cleaning tool to the cylindrical body.
