Which component is described as a short piping system that is flexibly produced?

The component described as a short piping system that is flexibly produced is indeed a flexible connector. Flexible connectors are used in gas piping systems to accommodate movement, vibrations, or thermal expansion and contraction. By being designed as a short, flexible system, they provide the necessary adaptability in situations where rigid piping would be inadequate. This is particularly important in areas where there may be shifts in the ground or structural movements.

In a liquefied petroleum (LP) gas application, a flexible connector helps ensure a reliable and leak-free connection between two fixed points, such as between a storage tank and the piping system. Their flexibility also aids in reducing stress on the joints and connections, which enhances the overall safety and longevity of the gas distribution system.

The other components listed, such as a fixed gauge, excess-flow valve, and liquid level gauge, serve different purposes in an LP gas system. A fixed gauge measures pressure or level in a static manner, an excess-flow valve is designed to shut off flow in the event of a leak or rupture, and a liquid level gauge indicates the level of liquid in a container. None of these serve the same function as a flexible connector in accommodating movement within the system.
