FAQ-9: Gathering Line Applicability

Go To FAQ#:

Question: Does the rule apply to gathering and other low-stress lines?

Answer: The rule does not apply to gathering lines. Section 192.9 has been changed to make this clear. The rule does apply to low-stress pipeline that meets the definition in 192.3 as a transmission line, but some requirements are slightly different for low-pressure transmission pipelines (i.e. <30% SMYS).
