Pressure Reduction Systems (PRS) are integrated, skid-mounted solutions designed and engineered to reduce and regulate gas pressure from high-pressure transmission pipelines to the specified downstream operating pressure with exceptional accuracy and stability. The system typically comprises pressure control valves (monitor–active configuration), slam-shut safety valves, safety relief valves, and a comprehensive instrumentation and control system, all assembled on a structural skid with complete interconnecting piping and instrumentation. Designed and fabricated in accordance with Saudi Aramco standards (SAES, SAMSS) and international codes such as ASME, API, and IGEM, the PRS ensures reliable performance under dynamic load variations while maintaining outlet pressure within specifications tolerances. Its modular architecture, redundant control loops, and maintenance-friendly layout provide high system reliability, operational safety, and long-term service life, making it ideally suited for industrial facilities, power generation plants, and city gas distribution networks.
