ABSTRACT:
A replaceable section (25) of force-cooling tubing assembly (21, 22) for attachment to a transition piece (5) of a gas turbine is comprised of two ends (54, 70) fashioned for attachment by removable unions (52) to adjoining parts of a force-cooling tubing assembly. When assembled thereto to complete the assembly, the replaceable section25provides for fluid communication between a manifold (3) and the transition piece (5) for either the supply or return of cooling fluid. A transition piece (5) in combination with two such assemblies, one a supply assembly (21), the other a return assembly (22), comprises a field-installable transition piece assembly (10) that provides for rapid and easy installation. The features of the replaceable section (25) include a relatively inflexible bracing zone such as a bracing member (58) having a support structure such as a lateral plate (60) that extends to the transition piece (5), a formed tubing bend (64) typically forming a U-bend, and optionally a second flexible component comprised of an inline flexible coupling (56).
