Piping Technology & Products, Inc. Performed Field Services for a Power Generating Plant in TexasPT&P was contracted to assist in the determination of pipe support maintenance at a power plant in Texas. The constant effort support springs with loads of excess of 9,500 lbs and the variable spring supports with loads of 450 lbs were marked for needing attention.

Inspecting Variable Springs for Performance

Final Assembly with Added Slide Plates
The pipe supports needing attention could not be set to the required installation position. A plan was initiated to recondition some of the support components such as turnbuckles and rods. This would allow a greater range of field adjustment to the pipe supports. During a planned shut-down, PT&P Field Service Units returned to the site to modify the existing supports. The initial phase of the modifications included bracing the piping in order to isolate and lock the supports in position. Then, they were disconnected from the system and modifications to the assemblies were completed. Afterwards, the supports were reinstalled and any necessary adjustments were completed. A total of eight pipe supports were modified or adjusted.
