When the pipe expands, we can separate the expanding pipe from the supporting structure by using slide-bearing plates. The purpose of moving them relative to each other is achieved.
The core of these slide-bearing plates is a graphite-embedded self-lubricating bronze plate. It acts as a bearing pad allowing mutual movement which consists of a bronze bearing plate filled with graphite + an upper and lower slide plate assembly.
The principle of operation is that the sliding plate underneath is usually welded to a fixed bracket that grounds the plate. another plate, on the other hand, is attached directly to the moving part. As the system moves, friction is transmitted at the intersection of the two plates.
