Reinigungsmolch

Pipeline cleaning tools

Pipeline cleaning pig made of soft open-pored polyurethane foam, reinforced by a waterproof polyurethane base plate. Effortlessly passes through valves, throttles, manifolds and 1.5 D-bows due to its high elasticity. Possible diameter reduction of 50%. On request, we can also supply a highly compressed version (with or without outer skin).

Application: for drying, removal of humidity or in case of soiling. Available in diameters from 75 – 670 mm, length 150 – 900 mm.
