FIELD: oil and gas production.
SUBSTANCE: invention refers to operation of pipelines. The installation for repair of the pipeline consists of a bath for glue equipped with freely rotating rollers, of a hollow cantilever for lay of film sleeve and of connected to a compressor gate facilitating pressure tight supply of a shell and the sleeve. Also the bath consists of three compartments: a vacuumising compartment, a higher pressure compartment and a compartment communicated with atmosphere. The vacuumising compartment and the higher pressure compartment are connected between them with a transitive chamber and are equipped with pressure tight closing covers whereon are assembled a vacuum metre, pressure gage and nipples for connection to a vacuum pump and the compressor.
EFFECT: improved properties and reduced time for saturation of multi-layer tissue shell with glue.
