In its introduction the ASME B31.3 Process Piping Code states that “The designer is cautioned that the Code is not a design handbook; it does not eliminate the need for the designer or for competent engineering judgment.” That statement, while true enough for the Process Piping Code, does not apply to the BPE Standard. In fact, the BPE Standard essentially exists as a component standard, a design handbook, and an industry standard. If the BPE Standard had a focal point around which all other parts revolved, it would be Part SD—Systems Design. Figure 7.1.1 shows how all parts of the Standard are interconnected with Part GR—General Requirements, which encompasses all parts with all parts feeding into Part SD. All parts and all subcommittees are on equal footing, but each part interacts in different ways with their counterparts.
