The modules consist in a 8" cilinder, with screwed caps each side. Both made of teflon. There have been appeared radial cracks in some modules. The age of the installation is 14 years. It could be a problem the influence of UV rays, because the modules can receive direct sunlight. Do you have any idea?. Also I have been searching some standard, but I have found only ASME X. Do you know any other?.
Thanks.
