Luis,
Clamshells can and have been installed while on-line, it is not for the faint of heart.
Sealable covers can be supplied with the expansion joints for hard boxing the bellows in during an emergency. This is done while the system is hot, although I suspect that most users forget to cut...
Guys, thanks for the response. I am not so much looking for design guidelines as I am contractors and engineering firms that consider this their speciality.
Anybody know who are the companies that specialize in the supply of safety relief valve vent piping systems? Or is this just typically handled by general piping contractors?
Thanks,
GB
