What is the maximum length allowed for hoses used in pressure relief device channels?

The maximum length allowed for hoses used in pressure relief device channels is 36 inches. This specification is important because longer hoses can increase the risk of pressure build-up and other hazards, which may compromise the effectiveness of the pressure relief system. Shorter hoses minimize the potential for gas entrapment and facilitate the proper operation of safety valves, ensuring that they can function effectively in releasing gas during overpressure situations. Keeping hose lengths within this limit also helps to maintain the integrity and reliability of the entire system, as longer hoses can introduce additional points of failure and increase the likelihood of leaks or other malfunctions. Thus, adhering to the 36-inch limit is crucial for safety and operational efficiency in CNG systems.
