Saltwater Corrosion of Ni-Al-Bronze Using Potentiodynamic Analysis

Product Number: 51319-13333-SG

Publication Date: 2019

The effects of saltwater corrosion resistance on Ni-Al-Bronze (UNS C63200) was determined using a double polarization curve. Samples were held at 1300ᵒ F to 1700ᵒ F overnight and then water quenched. One sample was given the standard anneal at 1225ᵒ F for six hours and then air cooled. The samples were tested in ASTM D1141synthetic seawater. Current as a function of voltage (versus the saturated calomel electrode) was measured. Both forward and reverse scans were applied to the samples. The forward scans showed distinct changes in the anodic peaks with the lower heat treatment temperatures having anodic peaks at higher voltages. The annealed sample had the lowest anodic peak.Key Words: nickel-aluminum bronze corrosion synthetic seawater heat treatment

Sanicro 35, a New Super Austenitic Stainless Steel for Demanding Wet Corrosive Applications

Product Number: MPWT19-14327

Author: Jonas Höwing

Publication Date: 2019

$0.00

A new super austenitic stainless steel has been developed for use in highly corrosive wet environments.
The new alloy, Alloy 35Mo, has the general chemical composition 27Cr-35Ni-6.5Mo-0.28N and PRE>52,
suggesting high resistance towards chloride induced localized corrosion. The Alloy 35Mo has excellent
corrosion resistance in chloride bearing environments, and has also shown surprising mechanical
properties with a combination of high yield strength, excellent ductility and low hardness. The main
applications for the new grade will initially be heat exchanger tubing, small dimension piping and hydraulic
& instrumentation tubing. Target industries are refineries, chemical and petrochemical plants and offshore
installations. This paper discusses Alloy35Mo, its properties, and a comparison with existing,
competing grades

Scaling problems in HS Orka’s Geothermal Power plants an overview

Product Number: 51319-13475-SG

Author: Geir Thorolfsson

Publication Date: 2019

$20.00

HS Orka has operated the Svartsengi Geothermal Power Plant since 1976 the Reykjanes geothermal system since 1982 and the 100 MW Reykjanes Power plant since 2006. Scaling problems have been observed in wells and in most parts of the surface equipment. This paper describes the various types of scaling encountered and the different fluid conditions where scaling is formed. The current methods of scaling mitigations will be provided and described how the plant operation can be made reliable in spite of scaling problems.

Scaling Risk Assessment and Remediation in Geothermal Operations Using a Novel Theoretical Approach

Geothermal power holds immense potential as a renewable energy source with low emissions utilizing the Earth's natural heat to generate electricity. With growing concerns over climate change and the need for sustainable energy alternatives, geothermal power can provide energy independence, economic benefits, and versatility. Mineral scaling has been recognized as a major hindrance in seamless geothermal operations due to the harsh and diverse operating conditions, which can cause significant issues resulting in higher operating costs while reducing energy production's efficiency and overall economic feasibility. Therefore, there is a growing need for a tool that can help in designing preventive and remedial strategies against mineral scaling and, in effect, ensure seamless operation while reducing costs associated with equipment failure. A few of the most commonly occurring scales in geothermal operations across different regions are amorphous silica (SiO2), metal silicates, and calcite (CaCO3). Formulating an effective theoretical framework to identify the critical conditions and characteristics of scaling solids is imperative in devising preventive and/or remedial measures. This multi-faceted problem requires the simultaneous modeling of solution thermodynamics and kinetics. In this work, we propose a novel modeling scheme through the incorporation of the classical nucleation theory (CNT) with the Mixed-Solvent Electrolyte (MSE) thermodynamic model. While MSE assesses scaling risk based on the effective evaluation of the solution chemistry, CNT provides kinetic information, i.e., an estimate of induction time, based on the continuum thermodynamics treatment of clusters. This work focuses on applying the novel theoretical approach in providing accurate thermodynamic modeling of the scales and subsequent applications of the kinetic modeling in deriving remedial techniques. The theoretical framework aims to provide a consistent approach for testing various what-if scenarios and aid in making the best operational solution in the development of flow assurance.

SCC Growth In BWR-NWC Of A Low-Alloy Steel With Intermediate S-Content Tested At K Between 50 And 70 Mpa√M

Publication Date: 2022

Stress corrosion cracking (SCC) of RPV steels has shown fairly quick initiation and high crack growth rates (CGRs) in simulated normal water chemistry (NWC) autoclave tests. Still the operating experience shows no known cases that reflect this high sensitivity. The bulk of these tests have been conducted on either high sulfur material, with significant dynamic loading and/or in high sulphate or chloride environments. Recent studies at PSI and GE have shown increased CGRs at 3-5 ppb chloride. This led to the limit for normal operating conditions in the EPRI BWR water Chemistry Guidelines [3,4] to be reduced from 5 to 3 ppb of chloride during the course of this project. The effects on the in-crack chemistry of test specimens vs. those of real cracks, and the effect of cladding on cracking in LAS have been debated.
