What does the term 'Drip' refer to in the context of NFPA 54?

  1. A container placed at a low point in a system of piping to collect condensate

  2. A method of measuring gas pressure in piping

  3. A type of gas leak detection system

  4. A specific type of gas valve

The correct answer is: A container placed at a low point in a system of piping to collect condensate

In the context of NFPA 54, the term 'Drip' specifically refers to a container that is installed at a low point in a system of piping to collect condensate. This is an important function in gas piping systems, particularly those that transport natural gas, as condensation can occur within the pipes due to temperature changes or moisture in the gas. The presence of a drip allows for the safe collection and removal of this condensate, preventing potential issues such as corrosion of the piping or the interference of liquid with the flow of gas. By managing condensate effectively, a drip contributes to the overall safety and efficiency of the gas distribution system.
