A chemical plant in the Netherlands which produces raw materials for use in the body care industry was experiencing major problems with the sealing reliability of their Shell and Tube Heat Exchangers. In operation the Shell and Tube heat ex-changers are subjected to constant temperature cycling, and even with a preventative maintenance plan in place premature failure could not be avoided.
