Abstract

PURPOSE: To provide a pipe-connecting apparatus wherein a sealing mechanism is provided between the ends of two pipes, the sealing mechanism being provided with a backpressure mechanism to which an accumulator is connected, and sufficient sealing effect being maintained over a long time after installation without no supplimentary means.
CONSTITUTION: If pipes 1, 2 are connected to each other on the sea-bottom, etc., an inert gas such as N2 gas is sealed in an accumulator chamber 19 in a socket body 5 under increased pressure, then the pipes 1, 2 being dropped to the sea- bottom at a predetermined site, and a spherical body 4 being inserted into the socket body 5. Then, if a pressure oil is fed from an outer oil pressure source to a passage 16 through a releasable block 18, a piston 11 drops, and the escape of the spherical body 4 being eliminted by a retainer 8, Then, a pressure control valve 23 being opened with an increase in the pressure in the chamber 10, a pressure oil being fed to a backpressure tube 7 to carry out sealing, and at the same time, a piston 20 being moved left. The piston 11 is maintained at the said operation site by the pressure of the inert gas in the chamber 19.
