METHOD OF MAKING REINFORCED FLEXIBLE HOSE WITH LEAKAGE INDICATOR |
摘要 |
A reinforced flexible hose that has at least one layer of stainless steel threads braided about the outer surface of the inner core and a transparent flexible polymeric covering located over the braided stainless steel threads, thereby protecting them from abrasion and corrosion. The covering is not in intimate contact with the circumference of each thread thereby trapping pockets of air between the covering and the threads. A moisture sensitive compound is dispersed through the stainless steel threads under the transparent covering. When the compound becomes wet, it changes from a first color to a second color indicating that the hose has failed.
