[MW:3144] RE: 3137] hot-oil traced line

you won't find any code or standards that says not to use pneumatic testing... but if you calculate the energy stored on testing your 10-12" pipe, it will be huge... I mean really HUGE! so safety takes priority... if anything goes wrong, I wish nobody is even near the pipe!
 
As already recommended... try to convince the client (if that is the origin of the idea) for a full NDT and service test. It is safer!
