Dephy,
Please consult the Design Specification. Classification and boundaries is a mandatory contents for this document.
Then look into NC/NF-1100, this should be helping.

Dephy,

When two different class of pipe welded together e.i. Class NC pipe butt welded to Class MC pipe the more restrictive will apply.
