ABSTRACT:
There is provided a protective joint for production tubing having a body portion and an increased diameter portion within a zone to be protected and including a transition ring formation and a plurality of first and second generally cylindrical annular protective rings coaxially locatable with the body portion and the increased diameter portion, respectively. The transition ring formation is located between the first and second protective rings [and may include a transition ring, a supporting ring and a compensating ring which are sealingly biased with the protective rings against two retainer by a biasing means] to [thereby] form a protective shield capable of accommodating longitudinal movement of the production tubing relative to the protective joint as well as flexing in the production string.
