What are the safety devices that protect gas cylinders from overpressure?

Gas Cylinder Valves are used to control the flow of gas through a cylinder. They help prevent the leakage of gas in the cylinder, as well as prevent the cylinder from getting completely empty. There are several types of gas cylinder valves, each with their own unique features and benefits.

Gas cylinder valves should be installed securely, and there should be a protective cap that covers them. This is particularly important in case the cylinder is in storage. It should be stored away from heat, mechanical damage, and electrical circuits. It should also be moved with caution, with a hand truck that is designed for this purpose. In addition, the valve must be clearly labeled with precautionary information.

Burst discs are another type of safety device that can protect gas cylinders from over-pressurization. They allow the gas to escape before the cylinder ruptures. The burst disc is designed to rupture at five-thirds of the service pressure on the cylinder, or 1.66 times the working pressure. However, you cannot always be sure that the disc will burst.
