1.0 Program Objective

The B31.3 Piping Checklist (and Rules of Thumb) are intended to help designers evaluating piping systems. Notes and warnings from the 2007 B31.3 piping code are included, in addition to situations where the B31.3 Code rules require special consideration. Safety, Analysis, Applicable B31.3 References, Risk, SIFs, Flexibiliites, and probability of failure estimates are presented in individual reports. Each report is discussed in detail in the body of this guideline. The reports can provide a record of the evaluation procedure and considerations that went into the piping system design.

Per 300(b)(2), The designer is responsible to the owner for assurance that the engineering design of piping components complies with the requirements of the B31.3 Code and with any additional requirements established by the owner. The calculations made in the B31.3 Piping Checklist are intended to assist the designer in satisfying that responsibility by drawing the designer’s attention to possible areas of concern. In all cases it is the designer’s responsibility to validate any conclusions or recommendations made by the B31.3 Piping Checklist and to verify that all items of concern are properly considered.
