FIELD: process engineering.
SUBSTANCE: invention relates to operation to main pipelines and serves to clean their inner surface. It may be used in oil and gas industry. Elastic collars of cleaner feature zigzag-like shape and are furnished with structural cord carcass with its threads arranged radially. Inner diameter of collar sealing element is coupled with fastening section edges by spring elements made up of radial sectors arranged regularly.
