Off-hand i do not recollect of how many years Belzona had withstood for a particular service duty and what is the life expectancy given for Belzona application for a specific exchanger or other usages in various industries - including Oil & Gas industry.

Perhpas some of the user industries who had long years of success may throw some information or light on this in this forum.
