Is It Normal for Newly Replaced Coal Gas to Make a Hissing Sound When Turned on

It’s normal to hear a sound when activating a gas cylinder.

change gas
Gas, usually in a gaseous state, is pressurized in the cylinder to liquify. Opening the cylinder’s valve triggers the conversion of this liquid gas back to its gaseous form via a pressure-reducing valve, a process that generates noise due to pressure changes.

Additionally, as gas exits the outlet, it creates friction with the gas pipelines, resulting in a hissing noise. This sound is evident upon opening the gas cylinder and dissipates once the cylinder is closed.
