Pressure Surges
Almost all fluid systems develop pressure surges which may exceed relief value settings. Exposing the hose to surge pressure above the rated working pressure will shorten hose life and must be considered in selecting the proper hose. A surge which may not be indicated on many commonly used pressure gauges, can be measured using specialized electronic equipment. The safety factor in systems where severe pressure surges occur can be increased by selecting the hose with a higher rated working pressure. |
