Device for cleaning pipe inner surfaces or channel inner surfaces, has two outer sealing sections, which are provided with sealing elements

摘要

The device has two outer sealing sections (110), which are provided with sealing elements. A central functional section (120) is provided with an outer circumferential wall (121), where an outer dimension of the circumferential wall is smaller than outer dimension of the sealing sections. The functional section forms a closed cleaning chamber. An independent claim is also included for a method for cleaning pipe inner surfaces or channel inner surfaces.
