New Vented Service Riser Designed For Natural Gas Delivery

摘要

Energy Control Systems, Inc. (ECSI) says it has developed and has applied for a patent for a new service riser designed to identify and vent leaking fuel gas. The ECSI-VENT™ service riser is used to transport pressurized gas from an underground supply line to an aboveground delivery point. The riser is said to be specifically designed to allow fuel gases that may leak along a service line or at an underground compression or stab connection at the riser to be vented to the atmosphere.rnJames M. Royston, president of the Pittsburgh, PA-based company, says the unique design of the riser's "transition head" permits gas that may accumulate in the space between the carrier pipe and the riser's protective casing to vent safely to atmosphere. The riser is available with either a flexible or a rigid casing.
