Abstract

The cleaning plug has a cylindrical body (5) with a front section (7), a rear section (8), and a middle part (9). Emerging from the plug material are solid free cleaning pins (6) which are distributed over the front and rear sections, with which they are integral. The plug has a valve (16) for air input into it to expand it from a basic size to one with a greater dia. The middle part (9) has a wall thicker than the front and rear sections, in order to form a reinforcement with less elasticity than the sections. It can expand radially to the same or lesser extent than the sections so that they maintain their cylindrical shape even in the expanded state.
