ABSTRACT:
A seal for ceramic flow tubes resistent to high temperature, pressure and corrosion factors is made by fusing a first polymer to the ceramic as a binding layer, fusing to the first layer a second flexible polymer layer chemically and temperature resistent to the process fluid, and holding the two layers under a resilient loading. The seal is highly leak tight, chemically durable, inexpensive to produce and repairable without sacrificing valuable components.
