Effect of Chloride on the SCC Behavior of Carbon Steel Welds Exposed to Concrete Pore Water under Anoxic Conditions

In all nuclear power generating countries, high-activity, long-lived radioactive waste is an unavoidable by-product of the contribution of this energy to the global electricity generation. Disposal in deep, stable geological formations is, at present, the most promising option accepted at an international level for the long-term management of these wastes. Geological disposal relies on a combination of engineered (man-made) barriers and a natural barrier (the host rock), in order to prevent radionuclides and other contaminants ever reaching concentrations outside the container at which they could present an unacceptable risk for people and the environment.

Stress corrosion cracking (SCC) growth in 300-series stainless steels (SS) exposed to high temperature water is known to generally increase with increasing levels of cold work. The influence of cold work on SCC has been reported for both oxygenated boiling water reactor (BWR) normal water chemistry as well as for hydrogenated pressurized water reactor (PWR) water chemistry.

Publication Date: 2017

$20.00

In this work, stress corrosion cracking (SCC) of X80 and X100 pipe steels under various cathodic protection (CP) levels in near-neutral pH environment was investigated. The results showed that X100 tended to form longer SCC cracks compared to X80 steel.

Effect of Oxygen Excursion On SCC Resistance of Tubing Materials

Product Number: 51323-18779-SG

Publication Date: 2023

Oil and gas production from highly saline reservoirs can present challenges to the completion materials. The most saline fields often require downhole injection of (low chloride) wash water to dilute the produced water and mitigate the threat of halite precipitation on the production tubulars. The present paper investigates the threats associated with the co-mingled wash water and production fluids with respect to common completion materials.

Environmentally-Assisted Cracking (SSC And SCC) Of Martensitic Stainless Steel OCTG Material In Sour Environment In 5%Nacl And 20%Nacl Solution

Product Number: 51322-17563-SG

Author: Yuichi Kamo, Yusuke Mizuno, Yasuhide Ishiguro

Publication Date: 2022

$20.00

Martensitic stainless steels for OCTG materials are widely used in sweet and mild sour conditions. Environmentally-assisted cracking (EAC) is a major corrosion-related issue when using stainless steels as OCTG materials. The EAC in specific oil/gas well conditions with sour environments is defined as sulfide stress cracking (SSC) and stress corrosion cracking (SCC). The SSC is a type of cracking caused by hydrogen embrittlement, which is attributed to a cathodic reaction under acidic conditions, while SCC is associated with an anodic reaction. SSC testing for martensitic stainless steels for OCTG material is often carried out at or near ambient temperature under conditions simulating condensed water, and SCC tests are conducted at higher temperatures under conditions simulating formation water and/or the brine availability test.

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

Product Number: 51324-20875-SG

Publication Date: 2024

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.

Expanding SCC Safe Use Limit of Alloy 718 for Sour HTHP Downhole Applications

Nickel alloy UNS N07718 (Alloy 718) is extensively used in the oil and gas industry. However, it is limited by NACE MR0175/ISO15156 which only permits use at a maximum of 200 psi (1.38 MPa) H2S partial pressure at 400°F (204°C). To expand the Stress Corrosion Cracking (SCC) safe use limit of Alloy 718, NACE TM0198 Slow Strain Rate (SSR) testing was performed first to identify an upper H2S limit (i.e., 650 psi [4.48 MPa]). NACE TM0177 C-ring testing subsequently qualified Alloy 718 at this high limit in modified NACE Level VII conditions, and also under 910 psi (6.27 MPa) H2S partial pressure in a simulated field environment (total 15 ksi [103 MPa]) based on equivalent dissolved H2S concentration. This is the highest service H2S limit reported for Alloy 718 and also evidence that validates the effectiveness of dissolved H2S concentration as new sour severity metric for Ni alloy SCC qualification.

This paper examines the relationship between stress corrosion cracking (SCC) threat modeling and the number of digs required to conclude that a pipeline is SCC free. Results show that when a reliable inspection prioritization model is used, few digs are required to infer that a pipe has a low probability of SCC.

Localized Corrosion of UNS S31603 in Aqueous Ammonium Chloride Environments at Elevated Temperatures and Low Dissolved Oxygen

Ammonium Chloride (NH4Cl) corrosion is prevalent in the refinery and petrochemical industries and its prediction, monitoring and control has been well documented. In Chemical plants, when NH3 and HCl are present in a gas-mixture and the temperature drops, NH4Cl can desublime. In the presence of water-vapor, NH4Cl desublime within components like heat-exchanger tubes, creating saturated wet salt deposits, causing general and localized corrosion.
