Analysis of Unexpected Leaks in AISI 316L Stainless Steel Pipes Used for Water Conduction in a Port Area

Autor: Borja Arroyo, Roberto Lacalle, José A. Álvarez, Sergio Cicero, Xabier Moreno-Ventas

Publikováno v: Applied Sciences, Vol 13, Iss 4, p 2598 (2023)

This paper clarifies the causes of a corrosion process observed in austenitic stainless-steel pipes, grade 316L, used for conducting freshwater in a port area. During the pressure test of the installation, before it was put into service, about five m
