Piping Technology & Products, Inc. Performed Field Services for a Power Generating Plant in Texas

PT&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.

PT&P’s objectives were to:

* Evaluate the pipe supports
* Determine state of performance
* Provide a plan of action
* Train personnel on-site to perform adjustments and replacement of supports or support components
* Provide final inspection of modified supports

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.

The upthrust constants (PTP Fig. 200-U) were fabricated from A36 carbon steel. Weighing at 4,150 lbs each, they measure 94” long, 27” wide, and 43” tall. They support loads from 90,700 lbs to 93,000 lbs with 4” of vertical travel. In addition, they are custom designed with extra supporting points for heavier loads. They are used to support the piping system from beneath the pipeline. Upthrust constants only allow for vertical travel and are used where horizontal travel is unacceptable. Standard load and travel testing was completed to assure quality and performance.

Constant Hanger Supports for a Power Recovery Plant

Constant Hanger Supports for a Power Recovery Plant

Constant support hangers are used to support pipes subjected to vertical movement. The (Fig. PTP 200) constants are designed to support loads from 4,000 lbs to 57,000 lbs. Each weighs approximately 1,500 lbs to 2500 lbs and has a travel of up to 4″ with an adjustable travel stop. Their sizes range from 15 to 100.

The advantage of an adjustable travel stop is that the constant is able to “lock in” at any position within the range of travel for a given constant. This alleviates the need for a total “shut down” of the piping system for temporary conditions such as hydrotesting, repair, or replacement.
