RE: Hi all, I am working on piping wor
More information is going to be needed before anyone can give you any helpful advice.
What is your commodity?
What is your piping NPS?
What is your design temp?
What is your design pressure?
A694 is the specification for carbon and alloy steel forgings under high-pressure transmission service.
A216 is the specification for steel castings for high temperature service.
Do you have copies of the ASTM standards?

I forgot to ask, what is your design code? And what is the contractors reasoning for wanting to use A216 over A694?

design code BS 1873,reason for change is the long time of delivery of required material A216.
