Abstract

Leakage of water utility piping system will create an orifice like situation to the water which is leaked from the water piping. When this happens it will create a phenomenon that called as water jetting. The present research concern the erosion effect of water jetting on NPS 8 carbon steel pipe. The 5mm diameter orifice was used as a source of jetting in sand particles that was jetted towards the pipe specimen. It is found that the thickness of the pipe decreases with time. The existence of tunneling effect was established through physical examination of the impacted surface. Determination of time taken for the pipe to rupture was established at 220 hours after continuous jetting. At 45 cm separation distance the pipe was totally uneffected by the erosive water jet.
