Effect of Acid Concentration and Temperature on Active Corrosion Rate of Stainless Steel and Nickel Base Materials

Product Number: 51319-13330-SG

Author: Björn Helmersson

Publication Date: 2019

Material selection of passivating materials is often based on the assumption of a limit for passivity. In essence this means that for a given environment the selected material should have a corrosion rate that is low enough to be considered negligible. The limit between active corrosion and passivity may be more or less fluid depending on both material and environment. Furthermore active corrosion at a predictable and reasonably low rate may in some cases be acceptable. This work has studied the effect of acid concentration and temperature on the corrosion rate of three different materials. The conditions have been chosen to be able to study both passive conditions and the increase in active corrosion rate as conditions become gradually more aggressive. The studied materials UNS S32205 N08904 and N08825 have been selected due to their relatively similar compositions except the increasing nickel content in each material.

Effect of Acridine and Myristic Acid on CO2 Corrosion During Intermittent Oil/Water Wetting

Product Number: 51323-19192-SG

Pipelines are the most effective way to transport oil and natural gas, particularly for their bulk transmission over long distances. Corrosion in oil and gas pipelines occurs because of the presence of dissolved corrosive gases, such as CO2 and/or H2S, in reservoir derived brine, and contact between this brine and the steel surface. The oil phase by itself does not cause corrosion and can even inhibit corrosion.

Effect of Additional Water-Jet Cleaning on the Surface Cleanliness and Coating Performance

Product Number: 51219-202-SG

Author: Heebaek Lee, Eunha Song

Publication Date: 2019

$20.00

The objective of surface preparation is to create proper adhesion of a coating over the substrate. Proper surface preparation is vital to the long life and effectiveness of a coating applied in corrosive service. In some projects, the owners ask for the additional water jet cleaning prior to blasting work.

Effect of Alkyl Tail Length and Concentration on Adsorption of Quaternary Ammonium Corrosion Inhibitors

Product Number: 51319-13004-SG

Author: Negar Moradighadi

Publication Date: 2019

$20.00

Application of inhibitors is an established and cost effective method to mitigate corrosion of mild steel. Conventionally surfactant-type organic inhibitors are frequently applied based on their critical micelle concentration (CMC) values and their adsorption were evaluated based on reduction in corrosion rate. In this work the relationship between CMC and inhibitor adsorption was explored using a quartz crystal microbalance (EQCM); two quaternary ammonium model compounds with different alkyl tail lengths introduced at concentrations above and below their CMC. The quaternary ammonium model compounds were synthesized in-house and characterized by 1H NMR prior to their use. Their CMCs were determined using surface tension measurements. It was found that at concentrations above and below CMC adsorption of the inhibitors is approximately identical and corresponds to their existing as multilayers on the substrate.

Effect Of Antimicrobial Halophilic Plant Extracts On Microbiologically Influenced Corrosion (MIC)

Product Number: 51322-18089-SG

Author: Stein, J.L., Skovhus, T.L., Chaturvedi, T., Thomsen, M.H.

Publication Date: 2022

Offshore oil production facilities are subject to internal corrosion, potentially leading to human and environmental risk and significant economic losses. Microbiologically influenced corrosion (MIC) and reservoir souring are important factors for corrosion-related maintenance costs in the petroleum industry.1 MIC is caused by sulfate-reducing prokaryotes (SRP), which can be Bacteria (SRB) or Archaea (SRA), with the main focus in literature being on SRB.^2–5 The microorganisms most frequently reported in literature to be responsible for MIC are the SRB; Desulfovibrio, Desulfobacter, Desulfomonas, Desulfotomaculum, Desulfobacterium, Desulfobotulus, and Desulfotignum, and methanogens.^2,5

Effect of Applied Stress and Precracking Parameters on KISSC of High Strength Steel Grades

Product Number: 51319-13183-SG

Publication Date: 2019

The NACE Standard DCB test Method D provides a measure of resistance to crack propagation in sour environment; expressed in terms of a critical intensity factor for Sulfide Stress Cracking. Testing conditions must be such to ensure crack initiation since is a crack arrest type of fracture mechanics test. To ensure crack initiation the formation of a sharp crack tip by fatigue precracking is permitted by the mentioned standard; however the conditions in which precracking procedure must be performed are not so well established and were modified over the years. Definition of pre-cracking load is crucial for obtaining the true value of since excessive load will produce an increment of the plastic zone at the crack tip that will delay crack initiation generating overestimation of that could not be otherwise noticeable. Despite the selection of pre-cracking load and procedure has a clear impact on Method D result criterion of NACE TM0177 has changed over the yearsand nowadays differs in the maximum precracking intensity factor defined for C110 in API 5CT. The main objective of this work is to quantify the effect of pre-cracking load on sour resistance for the High Strength Steel grades tested with different arm displacement. Tests were performed NACE A solution and SR39.3 solution for C110 and in NACE A for the future C125 grade at 24°C.

Effect of Applied Stress on the Selective Oxidation of Alloy 600 Exposed To PWR Primary Water and Rhines Pack Environments

Product Number: ED22-17328-SG

Publication Date: 2022

Alloy 600 is known to be susceptible to intergranular attack (IGA) and stress corrosion cracking (SCC) under pressurized water reactor (PWR) primary water conditions, leading to the replacement of some steam generator components with the more SCC-resistant Alloy 690.3 Despite this shift many Alloy 600 components are still found in service today. A substantial body of research has identified many underlying processes leading to the degradation of Alloy 600.

Effect of Blocking Compound on Electrochemical Corrosion Behavior of Wire Rope at Gulf of Mexico Surface and Subsea Temperatures

Product Number: 51320-14262-SG

Author: Suresh Divi, Swight Janoff

Publication Date: 2020

$20.00

Wire ropes with a sheathed spiral strand are commonly used for mooring applications in offshore oil and gas production. Each strand comprises a bundle of galvanized steel wires with a blocking compound applied to the outer layer of the wire bundle to prevent seawater from contacting the internal strands of wire if there is a breach in the urethane cover. The blocking compound and a sacrificial zinc layer on each strand of wire are designed to protect the carbon steel.

Depending on the water depth where the wire rope is being used offshore, it can experience a wide range of temperatures—from 22°C at the surface to 4°C at the seabed. Corrosion behavior of wires at these temperatures is critical, in case of breach in the urethane cover.

Immersion and electrochemical corrosion testing was performed on subsea mooring line wire rope with and without blocking compound in synthetic seawater at 4°C, 13°C, and 22°C. Samples of galvanized wire with and without blocking compound at the lowest temperature (4°C) did not exhibit any iron corrosion products even after 160 days of exposure to synthetic seawater. The corrosion rate of galvanized steel with blocking compound remained less than 2 mpy, while that for galvanized steel without blocking compound remained less than 5 mpy.
