Abstract:
An apparatus including a collar member dimensioned to encircle an underlying tubular and having a modifiable diameter to accommodate a change in a diameter of the underlying tubular. The apparatus further including a band dimensioned to encircle the collar member, the band having a modifiable length capable of changing in response to the tubular diameter change. The collar member may have a first section and a second section. A resilient member may be coupled to the collar member between the first section and the second section. A method including modifying a diameter of a collar member positioned around a tubular in response to a diameter change of the tubular, wherein modifying the diameter comprises changing a size of a resilient member coupled to the collar in response to the change in diameter of the tubular.
