hi guys!
my designer request to support lines with valves ranging from 6 – 24 inch at the stud bolt of the flange because of space constrain but i objected stating some obvious disadvantages such as bolts snapping as a result of the weight of the valve after along time but he seems not satisfied, is there any source , standard or what ever that clearly discourages this practice i can lay my hands?????
thanks :dry:

I’m unaware of any codes against this type of support, maybe individual company standards? However we use this type of support a number of times here in the oil fields and co-generation facilities that are constructed in this area. As your designer indicated they are primarily dictated because of space constrains, and I developed a detail to cover an installation for a small 2″ flange support [URL=http://s19.photobucket.com/user/11echo/media/Piping/FS-2_zpspoxoc61m.jpg.html][IMG]http://i19.photobucket.com/albums/b172/11echo/Piping/FS-2_zpspoxoc61m.jpg[/IMG][/URL]
But we draw the line size wise at 6″, anything above that has to have a more standard support design, weight and vibrations are the main issues …stud breakage, not an issue.
