Hi all,
We always have problems with our mechanics rigging off of system piping to help remove equipment. We tell them if they want to do this they should contact design engineering to do a pipe stress analysis first. This prompts them to rather look for another rigging point or tooling.
However, sometimes it is the only way. I have seen procedures where you must first drain the pipe, check hanger spacing and loads, etc.
Anyone heard or seen procedures on this or code rulings that this must not be done ?
Thanks
