We're looking into a job that specifies B31.9, which we don't own.

Does anyone know what the NDE rules of that code are?  We want to make sure our esitimate incldues the cost for any NDE required.

The code covers systems with "relatively" low pressure steam and condensate (150 psi max at 366F).

Based on B31.1, I could just assume that no additional NDE beyond VT is required; but it would be nice to know for sure.

Thanks.

Charles.
