Gas Pressure Regulating & Metering Equipment
Gas Pressure Regulating & Metering Equipment
HUAYI Natural Gas Pressure Regulating Skid is designed for medium- and low-pressure natural gas transmission and distribution systems where upstream gas pressure needs to be reduced and controlled according to downstream operating requirements.
The skid can integrate pressure regulators, safety shut-off and relief devices, isolation valves, bypass piping, pressure instrumentation and associated process piping within a compact equipment arrangement.
Depending on the required operating philosophy, the system can be configured with main and standby regulating lines to provide operational redundancy. Optional gas detection, telemetry, remote monitoring and control functions can also be incorporated according to project requirements.
Gas flow capacity, inlet and outlet pressure, number of regulating lines, safety protection configuration, instrumentation and control functions can be engineered according to project-specific operating conditions and technical requirements.
This equipment is mainly used for medium and low pressure gas transmission and distribution, especially for residential areas, direct combustion equipment and other gas supply. It has a standard structure and is suitable for natural gas, coal gas, liquefied petroleum gas and other non-corrosive gases. It is equipped with an overpressure protection device, and the pressure regulating branch adopts a 100% injection design. It can realize the automatic switching of the main and auxiliary to ensure uninterrupted gas supply, and the bypass is equipped with a manual regulating valve. It has good scalability and can add gas alarm and telemetry and remote control functions according to user requirements. It occupies a small area and has a beautiful appearance. It is suitable for indoor and outdoor installation and meets environmental protection requirements. It has a reasonable structure, complete functions, high reliability, simple installation and commissioning, and convenient maintenance.
Product Overview
