thickness will help to prevent the propagation of any cracks formed in the tubular the pattern of grooves depicted in fig1 is a continuous pattern of grooves 210 about the circumference of the body 200 with the grooves 210 intersecting to form a plurality of substantially identical shapes in the preferred embodiment the shapes are diamonds however the scope of this invention is amenable to other shapes including but not limited to polygonal shapes and interlocking circles loops or ovals not shown in one embodiment the profile cuts 205 are formed on the surface of the shapes created by the grooves 210 the profile cuts 205 are formed at a predetermined depth less than the grooves 210 so that the profile cuts 205 will not substantially affect the compressive or tension capabilities of the tubular 200 upon expansion the profile cuts 205 may be horizontal cuts vertical cuts or combinations thereof to divide each shape into two or more portions preferably the profile cuts 205 intersect the corners of the grooves 210 as depicted on fig1 fig1 also depicts inserts 220 interdisposed within the pattern of grooves 210 and profile cuts 205 the inserts 220 provide a gripping means between the outer surface of the tubular 200 and the inner surface of a larger diameter tubular not shown within which the tubular 200 is coaxially disposed.
