What is the minimum bursting pressure required for hose used for LP Gas liquid transfer?

The minimum bursting pressure required for hose used for LP Gas liquid transfer is 1,750 psig. This standard is established to ensure the safety and integrity of the equipment involved in the transfer of liquefied petroleum gas, which is under significant pressure. It is crucial that hoses are rated for pressures well above the operating pressure of the system to prevent failures that could lead to leaks or explosions.

Using hoses with a minimum bursting pressure of 1,750 psig ensures they can handle not only normal operating conditions but also unexpected surges or spikes in pressure. This is vital given the highly flammable nature of LP Gas, and any failure in the hose could pose serious safety risks.

Other pressure ratings, although they may seem adequate, do not meet the safety requirements set forth. For example, hoses rated at lower pressures are not designed to handle the stresses of liquid transfer at typical operating pressures, making them unsuitable for such applications. The choice of 1,750 psig balances safety while still being practical for use in LP gas applications.
