What are the layers used in a PTFE plate for pipe supports?

How do you bond PTFE to metal?

December 1, 2010
The most common method of attaching a slide bearing plate to supporting metal structures is through welding.When this approach is used a “lip” must be built since the welding's extreme temperature may break the bond between the low-friction material and the metal plate. A 0.25 inch “lip” is adequate for most welded installations. When welding cannot be used (for safety or other reasons) to attach the slide plates, bolting is the most common substitute.

What is a slide plate?

November 3, 2010

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.
