FIELD: machine building.
SUBSTANCE: press-fitting has lug in circumferential direction where into there is inserted packing ring of round section; also, pipe ends inside press-fitting. The first pressurisation is performed inside the lug. Additional pressurisation is carried out from the side of the pipe inserted into the press-fitting at distance from the lug, thus achieving unidirectional taper of the press-fitting and pipe, preventing disconnection. Also, there is disclosed the compression tool required for implementation of the said procedure.
EFFECT: simplified process of pressurisation.
