Oil and Gas Metering and Measurement Systems
EN-FAB Inc offers accurate oil and gas metering and measurement systems designed for compliance, precision, and operational efficiency across facilities. In both gas and liquid applications, pressure reduction regulation is required. In a gas distribution system, a network of transmission pipelines transports natural gas from the producing fields to consumers. Gas transmission pipelines normally operate at high pressures. As customers do not usually require gas delivered at such high pressures, it is necessary to control the pressure and flow rate.
Gas pressure and flow rates are controlled at pressure reduction stations located along the pipeline system. The gas pressure may start in the pipeline above 1,000 psig and end up at a plant or at a residence at a pressure as low as 15 inches of water column. Pressure regulating/reducing skids are packaged stations utilized by gas pipelines. The pressure-reduction system controls the supply pressure to gas users at a regulated value. Each system consists of at least two pressure-reduction trains—one operating and the other on standby.Each train will normally comprise two regulator valves in series. Regulator valves should be sized for the maximum anticipated volumes at the minimum anticipated inlet pressure during periods of maximum demand.
