RE: [PipingDesign] Plot plan layout

Thanks. Its a relief to know that other are also using the NFPA 30 (as everett mention the criteria comes loosely in different places like the nfpa 59A and nfpa 101 and some api stds). I was hoping that its consolidated in one place. The reAson for the query is that if there is a need to reduce the separation distance, we'll still be able to comply with the std.

The spacing criteria is important since it will ensure access to process units, for maintenance, fire fighting and quick evacuation. It willl lso limit the risk to adjacent facility such as toxi exposure. This is edge-to-edge dimension as opposed to centerline for piping.

i have come across a pipe routing that restrict movement of even case crane/forklift that it require us to burn some steel pipe/cable tray support. at one time we have to rent a 400 ton crane just to lift a large bore piping since the area surrounding the pipe rack is to crowded (if proper spacing was observed, a 50 ton crane would do nicely)..
