Erosion studies of SS316L using water jet machine (WJM) for the piping applications

Abstract This work aims to experimentally verify the wear resistance of the candidate material Stainless steel (SS316L) during the high-pressure fluid interaction. In the experimental study high pressure fluid was considered as water to replicate piping environment. The experiments were performed using the water jet machining to reach the high-pressure water. The angle of the contact of water jet with the specimen plate and the jet pressure were taken as parameters. Based on the experimental results, mathematical models were generated in correlation between the jet pressure and erosive wear by considering four basic models, linear, polynomial, power and logarithmic. The results revealed that the polynomial model holds good for all the angle of contact. Further, the crater formation is visible in optical microscope (OM) image, and the pressure has direct correlation with the erosion wear and the angle of contact has inverse correlation with the wear.
