Abstract
An arrangement for fixing two concentric tubes (1, 2) together by means of one or more pressure inducing members, preferably each formed as a pad (6); the member acts to press the tubes together; a support (3), preferably formed as a collar fixed inside the outer tube (1), is provided opposite the or each location of the or each member. The support is designed to maintain the circularity of the inner tube so that it can be readily withdrawn from the outer tube without jamming. This is useful for off-shore installations.
Claims16
A tubular clamping arrangement for fixing two concentric tubes together comprising:
- a pressure inducing member to force the tubes together at least one location of the outer tube;
- a support provided at the or each location opposite the pressure member;
- wherein said support being a collar, the pressure inducing member is formed as a pad of substantially the same thickness as the collar, the collar having a recess into which the pad can fit without protruding from an inner surface of the collar;
- and
- wherein at least a part of the pad is retained in the recess throughout its pressure inducing travel.
