The influence of gasket finish on the sealability of double-jacketed gaskets used in heat exchangers

摘要

Due to their large size, double jacketed gaskets used in shell and tube heat excchangers ar emanufactured by radial bending of pre-fabricated, jacketed strip and joined by butt-welding of the metal jacket ends. This paper reports the results of a study to show the influence of welding finish and other surface imperfections such as tool marks, on the gasket sealability.
