Concentric wrench for blind access opening in a turbine |
摘要 |
The concentric wrench includes an outer tube having flats at one end and a gripping surface at an opposite end. An inner tube has interior flats at one end and a gripping surface at its opposite end. With the inner and outer tubes disposed about a pressure transmitting conduit, the tubes may be inserted into a blind access opening in the outer turbine casing to engage the flats of the tubes against hex nuts of an internal fitting. By relatively rotating the tubes using the externally exposed gripping surfaces, the threaded connection between the parts of the fitting bearing the respective hex nuts can be tightened or loosened.
