In the majority of cases, bond between the material and its backing plate would become degraded in the presence of high temperatures. With PTFE, if the heat reaches to 350˚ F, the glue becomes weaker. For Graphite Slide Plates, the maximum temperature should be approximately 775˚ F.
Slide bearings are provided to decrease excessive friction forces that would be generated with direct steel to steel contact.
Structural Steel Components with PTFE, 25% Glass Filled Slide Plates
The PTFE is generally used as a slide plate either affixed to the supporting steel or the bottom of the pipe saddle. This PTFE component acts to provide a low coefficient of friction between the saddle and the supporting steel.
Stainless Steel Slide Plates Affixed to Bottom of Pipe Saddle
A slide plate is a component that can be fabricated from a variety of materials including PTFE, 25% glass filled, graphite, Bronzphite®, Marinite®, and stainless steel. The purpose of slide plates is to produce a low-coefficient of friction between a stationary support element and the moving pipe support component to reduce the forces generated as a result of pipe deflections during operation.
