FIELD: heat power engineering.
SUBSTANCE: cleaning member comprises thin and rigid ring-scrapers (0.3-1 mm) whose outer edges lie on the surface of a virtual sphere whose radius is less than that of the pipes to be cleaned by 1-3 mm, with the center positioning at the center of symmetry of the cleaning member. The specific weight of the cleaning members is close to that of the water (1 g/cm3). Passing through the pipes together with the cooling water, the cleaning members remove soft slime sediments and growing crystals of carbonate sediments.
EFFECT: enhanced quality of cleaning.
