PTFE Slide Plates

These slide plate assemblies are comprised of 3/32″ thick PTFE, 25% glass filled slide plates bonded to 1/4″ thick hot dipped galvanized carbon steel backing plates. They measure 139″ long by 11-1/2″ wide, and were designed for a pressure of 2000 psi at -320°F to 500°F. PTFE, 25% glass filled material provides a low coefficient of friction, is easy to install, does not require surface treatments, or grouting, and is unaffected by weather conditions. These type of slide plates are typically installed on top of a concrete pillar under a large vessel.

What is a bearing plate?

January 10, 2012

A bearing plate is also referred to as a slide plate. It is a component that can be fabricated from a variety of materials including graphite, PTFE, 25% glass filled, stainless steel, and bronzphite. 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.

What is a PTFE bearing pad?

A PTFE bearing pad is a slide plate made up of PTFE, 25% glass filled, material that provides a low coefficient of friction for most combinations of temperature and load. For most applications, PTFE, 25% Glass Filled, is adequate when the temperature is less than 400 degrees F.

What is PTFE?

PTFE is also know as polytetrafluoroethylene. It is used as a component of slide plates and functions as a low-coefficient of friction between a stationary support element and the moving pipe support component.
