Thanks Naren.

I agree with LRB's comment. It would be useful if the edition of the code was also quoted at the input stage.

Bom - unfortunately the auditors weren't familiar with Caesar II. Although they had an understanding of why it was used, they were required to make an official examination across all the piping design - not just stress specific.

One other thing then....can anyone tell me what I'm missing out on, from a code perspective by using 5.0 instead of 5.1?
