METHOD OF TREATMENT OF BUILDING HEATING SYSTEM Russian patent published in 2002 - IPC

FIELD: internal cleaning of tubes and components of heating systems; hot water and water supply systems; construction engineering; pressure testing of hot and cold water supply systems and heating systems. SUBSTANCE: method consists in flushing and cleaning internal surfaces of pipe line from deposits effected by impulses of hydraulic impacts of water at permissible increased pressure built-up at one end of pipe line with other free end communicated with atmosphere; water is supplied by means of hydraulic ram; besides that, pipe line is subjected to vibration due to change in modes and time of treatment accompanied by flushing; additional momentary adjustable impulses of hydraulic impacts of different nature are furnished in the amount of 20 to 100 impulses per minute at duration of 0.01 to 1 s with impacts of air impulses between them at intervals of 3 to 0.6 s and duration of 0.01 to 1 s; number of such impulses ranges from 19 to 99 per minute in automatic mode; air is supplied by compressor through supply or return pipe line. EFFECT: improved quality of cleaning; reduced power requirements. 2 dwg, 1 ex
