ABSTRACT:
An erosion-indicating safety fitting having a fluid passage formed within for connection in-line with a pipe and a cage of interconnecting breach passages formed into the block and surrounding the fluid passage, particularly at areas having a predicted risk of erosion. A pressure gauge, connected to the breach passages, registers a change in pressure to equal that of the pressure in the fluid passage should the material between the fluid passage and one or more of the breach passages be eroded by the flow of particulate-laden fluid within the fluid passage. The fitting can then be changed before compromising the safety of personnel and the environment.
