Instrument gas accumulators are designed to store and supply emergency stock of fry gas for pneumatic and hydro-pneumatic actuators of any valves on gas mains, gas distribution stations, compressor skids and other plants in case of failures due to depressurization of gas lines. Accumulators themselves are pressure vessels with inspection manholes and connections for piping and instruments. Product bodies are welded steel makes.
