摘要：
The present invention provides a support sleeve for supporting an internal pipeline apparatus in a pipeline. The sleeve (50) is provided with a number of deformable splines (54) around its circumference which keep the pipeline apparatus centralised in the pipeline during operation. The leading edges (64,66) of the splines (54) have chamfers (62) so that, when the sleeve (50) encounters a reduction in the diameter of the pipeline, the splines (54) deform in a direction transverse to the longitudinal axis of the sleeve. It this way, less force is required to move the apparatus and sleeve through a portion of pipeline of reduced diameter than is the case with conventional disc supports.
