What is the minimum working pressure design for non-metallic hoses used outdoors?

The ideal choice for the minimum working pressure design for non-metallic hoses used outdoors is based on safety and operational effectiveness. A minimum working pressure of 250 psi ensures that the hose can withstand outdoor conditions and the pressures commonly experienced in LPG or CNG applications.

This pressure rating provides a suitable margin for safety and performance, considering factors such as potential temperature fluctuations and exposure to environmental elements. It also accommodates the dynamics involved in the transfer of gases, preventing the risk of hose failure under typical operating conditions.

While minimum working pressure values lower than 250 psi might be suitable for certain applications, they do not offer the reliability and safety needed for outdoor use where conditions can be more unpredictable. Establishing a higher standard, like 250 psi, reduces the likelihood of failure and ensures that the hoses maintain their integrity when exposed to elements like UV radiation and varying temperatures.
