High-pressure flushing hose – Protection against damage

During cleaning procedures in sewer systems, high-pressure flushing hoses are exposed to mechanical stress due to internal pressure, as well as tensile, bending and frictional forces. In practice, guide rollers or hose guides are used to reduce these stresses. They help guide the flushing hose and the nozzle to a horizontal position in the sewer without kinks, therefore avoiding hose contact at the edges of manholes and pipes.
