ABSTRACT:
A blast joint comprising a series of standard length joints of production tubing is disclosed. The blast joint includes a series of cylindrical rings composed of an abrasion resistant material mounted about the tubular tubing joints forming a protective shield about the production tubing. A movable sleeve formed of cylindrical abrasion resistant rings is selectively shiftable to enclose and shield the tubing connection assemblies joining the production tubing forming the blast joint. The production tubing and abrasion resistant rings form a blast joint whose length exceeds the standard length of a single joint of production tubing.
