Pressure Reducing and Regulating Skids for Gas and Liquid Systems 
EN-FAB Inc provides pressure reducing and regulating skids designed to control pressure and flow in gas and liquid systems, ensuring safe and reliable pipeline operations. 

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. For stations serving multiple residential customers or other non-interruptible services, sufficient regulator capacity must be provided so that the failure of one regulator valve run does not reduce facility capacity below the required demand. Regulator valves in custody transfer stations are typically designed to fail in the open position.

EN-FAB, Inc. designs, engineers, and fabricates gas measurement, gas gathering and compression stations to industry standards and the exact design specifications supplied by the customers.The basic criteria for the design of gas measurement system consists of properties and conditions of flowing gas with rate, type and location of the station, and the code to which it is designed and built. It has been stated that "Absolute accuracy of gas measurement stations is imperative as they are the cash register of the facility and pipeline." The natural gas business is based on the buying and selling of this commodity Measurement is responsible for balancing the input (buying) and output (selling)

Complete engineering from the ground up ensures exactly what you want in your system. The unit design can start out with a complete set of specifications you have drawn up, or you may supply us simply a short-listing of measurement needs. In either case, our engineering staff will work with you to develop, review and complete, a finished set of specifications and drawings for your unit. EN-FAB can provide the experienced technical personnel necessary to oversee installation and start-up of your unit. Our field technicians can help calibrate and troubleshoot if necessary. Our measurement experts offer training for your personnel in our Houston facilities or in the field to ensure proper functioning of the system in the future.

We also offer complete services for the package, including: flow testing and calibration, simulated electrical testing, dead weight testing of pressure test equipment.EN-FAB has been in the metering and measurement business for over three decades and has acquired vast knowledge of do's and don’ts. EN-FAB specialists have the experience and qualifications to help you with your unit. We can help you avoid costly mistakes that may appear initially as cost saving. When you select an EN-FAB unit, you can have the “whole package” with its long service life and lowest total, long term cost.
