Low alloy steels (LAS) are widely used in the marine and offshore oil and gas industry for various applications from bolting to large pressure containing heavy wall forgings. These materials are subject to various types of corrosion (general or uniform, pitting, crevice, etc.) and degradation in seawater environment. However, their selection for the applications, in comparison with stainless steels and corrosion resistant alloys, is justified due to their availability, manufacturability, proven service history, and lower cost.

Austenitic stainless steels (SS), such as 304L and 316L alloys, are largely used for structural components in nuclear power plants due to their good corrosion resistance, especially under high temperatures and aqueous environments. However, operational experience on the primary circuit of pressurized water reactors (PWRs) has shown an increasing number of cases of stress corrosion cracking (SCC) on austenitic stainless steels components after long-term exposure.

Radioactive waste is stored in underground, carbon-steel double-shell tanks at the Department of Energy Hanford site. The waste is transferred between the tanks and other assets using the transfer lines spanning throughout the various tank farms at Hanford. The transfer lines consist of a pipe-in-pipe design, small diameter pipes, and are not piggable. Recent inspection data of the transfer lines have shown areas with corrosion on both interior of the encasements and exterior of the primary pipes, with nearly 50 percent wall loss on the primary pipes and nearly 25% wall loss on the encasement pipes due to pitting corrosion. The visual inspections of the transfer lines have shown presence of corrosion products near the pipeline risers and beyond. It has been hypothesized that the corrosion is predominantly due to the high humidity conditions and in some cases is driven by the presence of residual hydrotest water in the encasement and the associated contact with the safety significant primary pipe. Therefore, drying of the transfer lines could lead to corrosion mitigation. Experimental studies are being conducted to understand the effect of environmental conditions, especially, relative humidity and temperature, on transfer line grade carbon steel corrosion and on mitigating corrosion. The experimental conditions are selected based on the seasonal temperature changes, and relative humidity conditions ranging from 30 to 100 percent. The experimental data will be used as guidance for maintaining a dry environment that will help mitigate the transfer-line corrosion caused by the high humidity conditions.

Effect of Early and Late Presence of Sulfate Ions on Steel Corrosion Development in Alkaline Solution

Effective highway bridge design in terms of strength, service, and economy can be made using prestressed concrete including post-tensioned (PT) construction.1-2 Bonded PT bridge designs incorporate high strength steel strand within tendon ducts and encapsulated with cementitious grout.3-4 The grout provides a protective barrier layer for the steel by preventing direct exposure to the external environment as well as facilitating the natural development of a thin passive oxide layer on the steel surface in presence of the high grout pore water pH.

Effect of Elevated Temperatures (30-80°C) on CO2 Corrosion after Intermittent Oil/Water Wetting

The main goal of this research is to electrochemically determine the influence of temperature elevation (30 °C - 80 °C) on the wetting state and corrosion behavior of mild steel during intermittent oil/water wetting. The results obtained in separate experiments demonstrated that the corrosion mitigation effect of an oil phase (LVT-200 model oil) containing myristic acid (surface-active compound representing naturally occurring oxygen-containing compounds in crude oils) on CO2 corrosion decreased with temperature after intermittent wetting. The influence of the same temperature range on interfacial properties during intermittent oil/water wetting such as oil/water interfacial tension (IFT) and oil-in-water contact angle were also investigated. For model oil containing myristic acid, the IFT value was unchanged with temperature and could not be correlated to the corrosion rate. In the presence of the oil phase, the surface became more hydrophilic at 55 °C, which diminished the adsorption and persistency of the oil layer and decreased the corrosion mitigation effect. The effect of temperature on IFT and contact angle can depend on the nature of oil and surface-active compound.

The protection against corrosion of the pipelines of the Crossbridge refinery in the West of Denmark is described in this paper. During years the pipelines in this refinery suffered significant external corrosion despite a Cathodic Protection, CP, system was in place to protect two different environments, onshore and offshore, from one sole location. Of all the pipelines being under cathodic protection, one suffered from severe corrosion at specific locations. Initially, the CP system was intensively evaluated with the outcome that a replacement of the pipeline was the best option. However, only after detail investigation of the process, the installation of online ER-probes to monitor current, potential and corrosion rates and the evaluation of the foreign pipelines the possible issues were identified. Environmental conditions, soil and sea water resistivity, flow temperatures and foreign district heating pipeline all affected the corrosion of the largest of the export pipeline, a 24” pipeline. Conclusions of the investigation, updated design and mitigation measures will be described in this paper.

Effect Of Environmental Parameters On Atmospheric Corrosion Of Infrastructures Of Canada

Structural steel, which is a critical component of many infrastructures, can suffer from deterioration of steel by reaction with air and its pollutants known as atmospheric corrosion when exposed to the
environment. The risks associated with corrosion of newly-built and ageing infrastructure are high and their consequences costly. The recent International Measures of Prevention, Application, and
Economics of Corrosion Technologies (IMPACT) study led by NACE International (now renamed as
AMPP) has shown for Canada the estimated annual corrosion cost to be $51.9 billion, which is 2.9
% of Canada’s GDP.

Effect of Feathering on Coating Performance

Product Number: 51219-181-SG

Author: Patrick Cassidy, Michael Kibler

Publication Date: 2019

$20.00

Feathering is the process of tapering or blending-in an existing intact coating in preparation of applying a new repair coating. This industry common practice is intended to ensure good adhesion of the repair coating to the legacy coating, and to provide a seamless aesthetic transition for areas where maintenance painting is performed. There are no industry standard requirements for performing feathering, resulting in most specifications having their own unique definition.

Effect of Flow Velocity on the Corrosion Performance of Thermally Sprayed Aluminium Coating in Synthetic Seawater

This work focuses on the effect of flow velocity on the corrosion performance of Thermal Spray Aluminium (TSA) Coating obtained by twin-wire arc spraying. Cylindrical electrodes (12 mm diameter) were machined from an S355 steel rod and coated with 300 µm thick TSA (AA 1050). An analytical rotator was employed for testing the coupons at 50 rpm and 600 rpm for 10 d in synthetic seawater. Testing under stagnant conditions was also included. Open Circuit Potential (OCP) and Linear Polarisation Resistance (LPR) measurements were carried out at 18 ±2 °C to assess the flow velocity effect and calculate the corrosion rate. Within 5 days of immersion, the OCP became more positive at higher rotation speeds. White corrosion products and calcareous deposits were observed on the coupon surfaces after 5 days, and the corrosion rate decreased in all cases.

Environments in oil and gas industries are often characterized by high temperature and pressure, harsh chemicals, humidity, extreme stress cycles, radiation, and mechanical disturbances.^1,2 These extreme conditions degrade the ability of materials to perform, thus requiring enhanced protection through application of heavy-duty anti-corrosive and chemical resistant coatings that can withstand the aggressive environment.
