The required pressure piping wall thickness may be calculated according to ASME B31.3-2014 section 304.1.2 as follows 2( ) PD t SEW PY (1) where t = the pressure design thickness for internal pressure P = internal design pressure (gauge) D = outside diameter of the ASME B313 Design of Straight Pipe Under External PressureASME B31.3 Design Pressure Calculator - Pipeng ToolboxCalculate ASME B31.3 general pipe design pressure from diameter, wall thickness, wall thickness tolerance and design stress. The hoop stress is equal to the design stress at the design pressure. The maximum design internal pressure includes the effect of external pressure (relevant for piping with external pressure only).

After all, a CRN registration is a registration is a registration. This response would seem to be in line with the idea that, when considered in their entirety, both codes are equal. But when considering CRN (Canadian Registration Number) requirements, this idea is incorrect in many ways.
