High-pressure flexible cylinder leads are intended to connect industrial gas cylinders, or packs of cylinders to a supply point of gas pipeline systems, (eg high-pressure point valves, manual manifolds or auto change-over manifolds).
Instead of having an external “anti-whip” cable, these leads have an internal safety cable that in the event of a failure, the cable activates internal shut-off valves. Not only does the internal shut-off valves prevent whipping of a failed lead, but they also prevent the gas from being released to the atmosphere from the cylinder or from the downstream pipeline system. Preventing accident release of gas can important when working with flammable, asphyxiant, oxidizing, or toxic gases, or when cylinders are located in confined or poorly ventilated areas. Failure of leads can be caused by accidental damage to cylinders, falling cylinders, “drive-offs” without disconnecting leads from manpacks, or by long term wear and tear.
