Abstract:
1. An erosion-indicating pipe fitting comprising: a unitary body having a fluid passage formed therethrough from an inlet to an outlet and an outer surface; a plurality of breach passages formed in the body spaced from and around the fluid passage forming intervening material therebetween, two or more of the plurality of breach passages, each being at a different position relative to the fluid passage and being fluidly interconnected for forming at least one chamber and at least one pressure sensor in fluid communication with the at least one chamber, wherein an amount of the intervening material is sufficient to maintain pressure integrity of the fluid passage during operation and the unitary body is effective to maintain pressure integrity of the body when the intervening material is breached; and wherein, when the intervening material of at least one of the plurality of the breach passages is breached, a change in pressure in the at least one chamber indicates erosion of the fluid passage.
