摘要
Method for tightly jointing a sleeve to a submarine pipe laid on a very deep sea-bottom, characterized by the preliminary stages of providing a series of grooves on the inside surface of the sleeve, and of filling each one of said grooves with two half-rings made of a material collapsible under high pressures up to a 70% variation of its volume. A type of such a material is moreover described.
