Most importantly, Ameron  piping and fittings are Hot/Forced Cured Epoxy systems, which are superior to cheaper Cold Cured Polyester systems offered by competitors, the latter being susceptible to in-service deterioration and cracking due to the inferior polyester resin and the cold curing process not being as stable as hot curing.
Furthermore, Ameron offers a comprehensive selection of epoxy-bonded, flanged or O-ring joint systems, including a double-O-ring dresser coupling made entirely of non-metallic parts.
By way of marine references from the Greek market, Ameron boasts plenty, including a number of first class Owners. You may contact the responsible Engineers and discuss in detail their experiences with GRE. Some of Ameron's clients are as follows:
