ASME B31.3 vs. sanitary tubing

[Spike2000]

hey folks
we currently have a job that must meet B31.3 spec/code..
piping no issues, straight forward
what about sanitary tubing and fittings? which most sizes have a .065" wall
and are for the dairy, sanitary, beverage and pharma, industries.
tubing is talked about, but is tubing covered under B31.3?

so if we weld together tubing components (tees, elbows...) will they need to comply to B31.3?

thank you
