Pipeline Safety: Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences
Traduction automatique locale · Langue originale de la source
Résumé
The National Transportation Safety Board (NTSB) has made a safety recommendation to PHMSA that excess flow valves be installed in all new and renewed gas service lines, regardless of a customer's classification, when the operating conditions are compatible with readily available valves. In response to that recommendation, PHMSA is seeking public comment on several issues relating to the expanded use of excess flow valves (EFVs) in gas distribution systems. PHMSA is also interested in seeking comment from gas distribution system operators on their experiences using EFVs, particularly from a cost-benefit perspective.
