Answer :
Final answer:
The maximum burst pressure required for LPG hoses is 550 psi (d).
Explanation:
The maximum burst pressure for LPG hoses refers to the amount of internal pressure that a hose can withstand before it fails. This is an essential safety factor in the design and selection of hoses used in the transportation and handling of LPG.
Different organizations and regulatory bodies have set standards and guidelines for the maximum burst pressure of LPG hoses. For instance, the National Fire Protection Association (NFPA) 58 standard for LPG storage and handling recommends a minimum burst pressure of 550 psi for Type B and C hoses used in LPG applications. Similarly, the European Standard EN 1763 for LPG hoses also specifies a minimum burst pressure of 550 psi for hoses used in LPG service.
Therefore, based on the authoritative sources mentioned above, the maximum burst pressure required for LPG hoses is 550 psi, which corresponds to option (d) in the question. It’s important to note that using hoses with lower burst pressure ratings than recommended can lead to catastrophic failures, posing significant safety risks and potential property damage.
