PTFE Slide Plates Designed for an Oil Refinery in Texas

PT&P custom designed PTFE slide plates for an oil refinery in Texas. These slide plate assemblies are comprised of 3/32″ thick 25% glass filled (PTFE) slide plates bonded to hot dipped galvanized carbon steel backing plates. The assemblies measure 47-1/2″ long by 36-1/2″ wide and 45″ long by 16″ wide. PTFE material provides a low coefficient of friction, is easy to install, does not require surface treatments, or grouting, and is unaffected by weather conditions.

113 F-Type Variable Spring Cans with PTFE Slide Plates

July 16, 2012

113 F-Type Variable Spring Cans with PTFE Slide PlatesThese F-Type variable spring cans were designed with PTFE, 25% glass filled slide plates for a local oil refinery. Slide plates are used to reduce the friction between the load flange of the spring and the pipe support. This allows for easier adjustment of the spring’s installed height. These variables include external travel stops. The external travel stops are sometimes referred to as universal travel stops and can be utilized to adjust the installed load (also called the cold load) to other installed loads within the working range of the spring. 113 variable springs were supplied for this job. The variables have an installed load ranging from 95 lb. to 11,000 lb. and an operating load ranging from 90 lb. to 10,703 lb. They are part of a plant expansion and will be used to support horizontal piping in an oil refinery.

19 Sets of Phosphorus Bronze and Stainless Steel Slide Plate Assemblies for Supporting Vessels

September 14, 2010

19 Sets of Phosphorus Bronze and Stainless Steel Slide Plate Assemblies for Supporting Vessels

The slide plate assemblies are fabricated from stainless steel, phosphorus bronze, and carbon steel. The 2″ thick carbon steel base plate is securely anchored to a concrete foundation, and the stainless steel slide plates are affixed to the base plate by countersunk attachment bolts. The phosphorus bronze slide plates, with machined grooves on the underside are placed on top of the stainless steel plates.

Underside View of Phosphorus Bronze Slide Plate Closer View of Polished Stainless Steel and Grease Fitting

To allow for lubrication between to the contact surfaces of the two slide plates, grease is added through a fitting on the side of the bronze slide plate. The fitting allows access to a channel in the center of the bronze slide plate that leads to the grooves. A hole is located in the 2″ thick base plate to allow for grout to be poured through after installation.

10 Feet Long Graphite Slide Plates for a Plant in Alberta

The top sheet of graphite measures 1/2″ x 11 1/2″ x 115 1/2″. This particular design also includes a bottom sheet of graphite with the same dimensions, but only 1/4″ thick. Each individual graphite sheet is bonded to a hot dipped galvanized backing plate with a 1/2″ lip all around for full welding. In an application where the pipe has large amount of movement due to thermal expansion, slide plates can be utilized to eliminate friction between the pipe support and the supporting member. Graphite is used when the slide plate must function at high temperatures. These particular graphite slide plates are designed for 1000ºF.

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.

Inspecting Variable Springs for Performance

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.
