Electrochemical Assessment Of The Influence Of Temperature On The Pitting Corrosion Reistance Of Metallic Materials In Brines

Product Number: 51322-17738-SG

Author: Helmuth Sarmiento Klapper, Sebastian Jesse

Publication Date: 2022

$20.00

Several industrial applications including the chemical industry and oilfield technology involve frequently halide-containing streams at elevated temperatures, that challenge the pitting corrosion resistance of metallic materials. Pitting susceptibility becomes not only a reject criterion for materials selection during the design stages of engineering components used in these applications. It also constitutes a significant limiting factor to the service life of these components once in service. Therefore, the characterization of the pitting corrosion resistance of metallic materials including the influence that operational factors can have on material’s susceptibility is crucial.

Microbial influenced corrosion is a type of corrosion caused by microorganisms attached to the metal surface or by their activity. The first one who noted the MIC was Gaines in 1910 [1], followed by research about the graphitization of cast irons in anaerobic soils in 1934 [2]. Nowadays, attention to MIC problems increased significantly.

The power plant is a natural gas-fired, combined cycle plant with three combustion turbines and a single steam turbine. A large stainless steel surface condenser is used to condense steam off of the turbine, and provide high purity steam condensate return to the boiler system. The steam condenser was put into service approximately 15 years ago. This plant takes makeup water for its open recirculating cooling tower water system from a river location that is inland from an ocean coastal area.

Evaluation of Seawater Treatments to Mitigate the Corrosion Rate of Carbon Steels and CRAs Rigid Pipeline During Pre-Commissioning Operations and Long-Term Wet Storage

Product Number: 51324-21050-SG

Once installed at the seabed, subsea rigid pipes in Carbon steel (CS), Low Alloys Steels (LAS) or in Corrosion Resistant Alloys (CRAs) can be wet stored for various durations. During this idle period, the lines can be filled with natural seawater generally treated with different types of chemicals, to mitigate localized corrosion initiation of stainless steel or the general corrosion of carbon steel. The chemicals are usually oxygen scavengers combined with or without biocides and corrosion inhibitor. Field experiences show that satisfying efficiency is obtained with some chemical’s combination. However, only few data are available in the literature to quantify separately the actual benefit of these chemicals and their combination. The needs to investigate sustainable alternative chemicals for these wet storage operations are also anticipated. In order to quantify the individual and synergistic effects of the selected chemicals, API 5L X65 carbon steel and UNS S31603 stainless steel were exposed for one year in seawater treated by different available combinations of oxygen scavenger, biocides, and corrosion inhibitors. Environmental-friendly chemicals have also been assessed as possible alternatives to conventional biocides. The corrosion rate of carbon steel coupons immersed in specific exposure cells, that simulate the confined exposure conditions during the wet storage, have then been determined by weight loss measurements after 3 weeks, 2, 6, and 12 months. The impact of the treatments on the corrosion rate and the bacterial activity have also been studied by Dissolved Oxygen Content (DOC) and Open Circuit Potential (OCP) monitoring, Electric Resistance (ER) measurements, and bacterial analysis. The current investigation shows that low DOC levels have been achieved which inhibited the so-called “biofilm ennoblement” of stainless steel. Thus, no corrosion occurred for UNS S31603. Such results are also applicable to most CRAs under similar exposure environment. The synergic effects of oxygen scavenger, biocides and corrosion inhibitor on the corrosion rate of carbon steel are also discussed.

Evaluation of Susceptibility of 316L to Stress Corrosion Cracking in Aqueous Ammonium Chloride Environments with Low Dissolved Oxygen

Product Number: 51324-20875-SG

Author: Jonas Sa; Alexander Saul; Monir Aljaradli; Dana Abdeen; Nicholas Laycock

Publication Date: 2024

$40.00

Corrosion of stainless steel in applied industrial environments continues to be an area of concern for various refining operators. It is well accepted that a certain concentration of dissolved oxygen is required for chloride stress corrosion cracking (SCC). However, there are some environments where it is suspected that chloride SCC can occur even in the absence of dissolved oxygen. The susceptibility to SCC of 316L stainless steel has been studied in the pursuit of extending operating boundaries at higher temperatures under low dissolved oxygen concentrations. Slow strain rate tensile (SSRT) tests have been carried out for various temperatures and ammonium chloride concentrations under low dissolved oxygen conditions. The susceptibility to SCC was assessed in terms of the relative reduction in area (RRA). Detailed fractography and cross section inspections were used to identify the damage mechanisms. The implications of this behavior and its influence on improving material selection have been discussed.

Field Application of Corrosion Resistant Weld Overlay in Ultra-Supercritical Coal-Fired Boiler Waterwalls

Product Number: 51320-14660-SG

Author: Jun Jiang, Bingtao Li

Publication Date: 2020

$20.00

Weld overlay has been successfully used to mitigate high temperature corrosion issues in coal-fired boilers since the1990s, such as in waterwall and superheater/reheater area. Weld overlay is typically applied in shop or field by using Gas Metal Arc Welding (GMAW) process for boiler waterwall application, and the overlay welding is performed in vertical down welding mode (3G welding position) in subcritical and supercritical boiler waterwall applications. With the rapid development of coal-fired boiler market in China, ultra-supercritical boilers are becoming the dominated boiler type which often has spiral waterwall design. Most of ultra-supercritical coal-fired boiler waterwall consists of CrMo steel tubes, which could suffer severe high temperature corrosion attack after the installation of low NOx burners. It is expected that weld overlay could provide a long-term high temperature corrosion protection for ultra-supercritical boiler waterwall based on previous weld overlay study and application experience. However, for the spiral waterwall with inclined tube design, its field overlay welding is highly challenging and significantly different from typical vertical boiler waterwall overlay welding. The challenge and difference include welding position, welding sequence, welding parameters, and overlay properties, etc. This paper presents a successful field application of 309L stainless steel and 622 Ni-based alloy weld overlay on the spiral waterwall of an ultra-supercritical coal-fired boiler, including the welding development, simulation, and experience of overlay welding on the inclined tubes, along with the characterization of the weld overlay applied.

Product Number: 51322-17935-SG

Author: Björn Helmersson

Publication Date: 2022

$20.00

Stainless steels and Ni-base alloys are often considered as construction materials in applications where highly corrosive conditions are expected. High levels of halides, low pH and high temperatures are factors that often contribute to the selection of such materials.

Ten different alloys have been included in this work, representing a range of highly alloyed stainless steels and Ni-base alloys. The purpose has been to evaluate the corrosion resistance of stainless steels with alloying content in the 6Mo range or higher, and competing Ni-base materials. The austenitic grade N08904 and two super-duplex grades have also been included for reference.

Stainless steel is selected for use in the municipal waterworks industry because of its inherent corrosion resistance properties. Designers oftentimes overlook the associated problems with coupling stainless steel with carbon steel metals. When these materials are electrically connected and placed into aqueous environments (immersion service) accelerated corrosion of the anodic carbon steel metal is initiated.
