| description | A plurality of tube shields interlock with each other to protect the weld of a securement strap used to secure the shields to a tube of a power plant. The tube shield comprises a semi-cylindrical longitudinally extending tube member terminating at a first and second end. The first end is provided with a tongue portion and a stepped portion. The second end is provided with a flanged portion and a pair of longitudinally extending bayonets. A securement strap is wound about a tube to be protected and the tongue portion of the tube shield. Each end of the securement strap is then welded to the tongue portion. A second tube shield is then placed adjacent to the first tube shield. The flanged portion of the second tube shield overlaps the tongue portion, securement strap, and stepped portion to provide protection from the hostile environment of the boiler. The bayonets are inserted between the boiler tube and the securement strap and provide a wedge-like interlocking assembly to securely fasten each tube shield to one another and to the boiler tube. Successive tube shields may be utilized to protect any desired length of tubing. |
