Re: Equipment foundation

the rule that ive always followed is that the piping at the nozzle interface must not exceed the equipment nozzle stress allowables - valves or no valves attached. And if an isolation v alve is attached, then it must be accessible and can be safely operated - with or without a platform.

A platform is cool but its not just possible to install it all over the plant and the operators knows this and so does the safety honcho.

Can u imagine working in a plnat surrounded by platforms, ladders with cage, handrails, etc of every size and shape - must be a maintenance nightmare.
