FIELD: process engineering.
SUBSTANCE: invention relates to pipeline transportation and may be used for cleaning pipeline inner surface of sediments. In cleaning, required gas and fluid pressure and flow rate are ensured by consecutive feed of fluid and gas into chambers formed by hoses arranged coaxially downstream of pipeline cleaner. By varying hose diameter and fluid pressure, volume of said chambers is varied to feed water and gas to cleaner. Proposed device comprises hoses to make chambers with pipeline, and chamber communicated with gas feed system. Pipeline inside and chamber formed by outer and inner hoses are communicated with fluid feed system.
EFFECT: possibility to clean pipeline with air holes.
