Many meters of stainless steel tubes are placed in a helix configuration within a plastic sheathing structure creating confined areas with alternating clamping force along the tube lengths. metals & mining riser corrosion ferric chloride flowline corrosion...

.... The requirement of low viscosity for chemical injection through capillary strings and umbilicals make methanol the solvent of choice in many cases. Products formulated with methanol that contain chlorides and a low amount of water (less than 5 wt. %) frequently hinder the ability of stainless steels and corrosion...

... ABSTRACT X-ray diffraction (XRD), electron probe microanalysis (EPMA), and scanning transmission electron microscopy (STEM) with focused ion beam (FIB) lift-out sample preparation techniques were used to study corrosion products in a 304L (UNS30403) stainless steel fluidized-bed reactor...

... ABSTRACT In this paper, the hydrogen induced stress cracking (HISC) susceptibility of 25Cr duplex stainless-steel tubulars produced through hot extrusion with- and without subsequent cold drawing, forging and centrifugal casting have been examined. Two different test methods have been used; i...

... and non-optimized materials selection, causing severe corrosion and cracking issues. In both cases, the equipment is a fixed tubesheet type of heat exchangers (one is vertical, and another is horizontal) and the materials are mainly 300 series stainless steels. These two cases also demonstrate...

... ABSTRACT Localized corrosion (pitting and crevice) is one of the main causes of damage of stainless steels in industrial applications. In order to study the corrosion behavior of stainless steel in the presence of chlorides, the Pedeferri’s diagram can be used. The diagram, originally...

... at laboratory scale. In this study, the influence of the depth on the cathodic protection criteria of carbon steel and stainless steel was investigated in intermediary (1020 m depth) and deep water (2020 m) at the same location. For this purpose, at set of corrosion and environmental sensors, as well...

... ABSTRACT The application of Corrosion Resistant Alloys (CRA) in harsh environments and severe services is gaining a leading position across the Industry. Among the different CRA, Duplex & Superduplex stainless steels (DSS) represent an often-interesting choice in terms of cost-benefit...
