The present invention relates to a method for interconnecting adjacent expandable pipes by Laser Beam Welding (LBW).

Method for interconnecting adjacent expandable pipes

A method is provided of radially expanding a connector for interconnecting a first tube to a second tube, the connector including a pin member extending into a box member. The pin and box members have cooperating support means arranged to support the pin member so as to prevent radially inward movement of the end portion of the pin member relative to the box member. The method involves radially expanding the connector, and supporting the pin member so as to prevent radially inward movement of the end portion of the pin member relative to the box member.

Radially expandable tubular with supported end portion

Method for sealing an annulus between two solid tubulars or between a solid tubular and a borehole which comprises the use of a thermoset or thermoplastic material in forming the seal between at least part of the outer surface of a tubular and at least part of the inner surface of the other tubular or the wellbore in which the seal is formed by expanding the inner tubular.
