Gas Pipeline Operations

Gas transmission lines across the country utilize a complex system of both compressor and pumping stations throughout the line network. These compressor stations keep the gas moving to supply cities along the way.

In the event of a utility outage, power must be maintained to cycle critical valves as needed. The natural gas pipelines rely on electric compressors and electric pumps to maintain pressure to keep the gas flowing. In the case of an electrical outage, electric pumps and compressors will not operate, bringing the natural gas supply to a halt.

Restoring the supply of natural gas once is it stopped is not an easy proposition, as pipeline personnel must close all of the pipeline meters, purge the system with compressed air, re-pressurize with gas and then physically visit every location to reignite every pilot light.

Maxpro Technologies’ pipeline air amplifier system can provide large storage tanks of high pressure air to keep these valves pressurized during an outage.

The system consists of an air pressure amplifier with a large storage tank (in this case, 4 systems with 30 gallon, 200 gallon and 400 gallon tanks) and the necessary components for a turnkey system.

The compressed air amplifier will take the standard shop pressure, raise it, and store it in large tanks. These tanks will deliver the needed air pressure to cycle the compressor station valves during an outage, and keep the gas flowing to the end users without interruption.

This specific application will store ‘emergency air’ to cycle critical valve actuators at 150 psi if normal utilities are down.

Maxpro Technologies has equipment to provide high pressure air to critical gas pipeline valves during emergency situations. See photos of more air amplifier systems by clicking here.
