PIPELINE SAFETY REGULATORY INTERPRETATION
Note: This pipeline safety regulatory interpretation applies to all operators that are subject to the rule under Federal or State law.
SECTION: 192.363(b), Service lines: Valve requirements.
SUBJECT: Use of soft-seated valves.
FACTS: §192.363(b) says, "A soft seat service line valve may not be used if its ability to control the flow of gas could be adversely affected by exposure to anticipated heat."
QUESTION: Does "anticipated heat" refer to a possible fire, or simply hot gas flowing under normal operating conditions?
INTERPRETATION: "Anticipated heat" refers to any possible source of heat to which a valve may be exposed, including fire, that would make the valve inoperable. The primary industry standard that has been used to demonstrate the fire resistance of valves is "Fire Test for Soft- Seated Ball Valves," API 607.
