FIELD: construction.
SUBSTANCE: invention relates to construction of pipelines. Proposed device comprises sealing assembly 10 including cylindrical case and cylindrical working member coaxially mounted thereon and configured to radially expand when overpressure is created in said cavity. In the housing there is a compound supply unit 12, a compound component dispenser formed by piston unit 11 and a pneumatic automatic control unit 13. Working cavities of the dispenser for each component of the compound are connected to unit 12 for feeding the compound. Elastic working element is made with channel for supply of compound into annular gap in zone of weld joint, which is connected to unit 12 of compound supply, and with channel for gas pumping from said annular gap. Unit 13 of pneumatic automatic control is designed to control operation of dispenser and unit 12 of compound supply and creation of excessive air pressure in cavity of working element of sealing assembly 10.
EFFECT: invention can be used for internal insulation of pipe joint with inner protective coating.
