Watermain failures are not often recognized as corrosion but are usually referred to merely as “watermain breaks” because watermain pipe appears sound prior to failure. Some of the causes of watermain breaks are poor design, improper installation, surge or water hammer, soil movement, manufacturing defects, impact, internal corrosion, and external corrosion. Figure 1 shows some of the possible causes of the DI pipe.

Concrete and other cementitious surfaces are porous materials that will allow water and soluble contaminants to penetrate the structure leading to degradation. The effects of degradation can include efflorescence, laitance and physical defects such as cracking and spalling. Waterproofing concrete can protect it from freeze/thaw cycles, increase chemical resistance, and provide protection to imbedded reinforcing steel.

Erosion-corrosion plays an important role in determining the durability of the erosive/corrosive slurry handling equipment. The combined action of erosion and corrosion produces a high degradation rate. Material loss rate due to erosion-corrosion is usually significantly higher than the sum of material loss rate due to pure erosion and pure corrosion acting separately. The degradation in erosion-corrosion is primarily by matrix extrusion due to abrasive particle impact.

Weathering Of Industrial Coatings: Correlation Between Three Years Outdoor Florida Exposure And Four Accelerated Weathering Methods

Product Number: 51323-18869-SG

Implementation of classification and certification programs for durable industrial and infrastructure maintenance coating systems is hindered by a lack of test protocols to reliably accelerate the aging process and estimate service lifetime. This gap in the industry also hurts development efforts to
reformulate or add new color choices to existing product lines. The first problem can be addressed by performing long-term weathering testing at outdoor exposure sites in places like south Florida and Arizona, but the need to wait 5 or 10 years or longer to confirm a classification or certify a product makes such schemes difficult to implement and ultimately reduces their value.

Boiler system is one of the most critical systems for a utility plant. A utility plant had experienced high percentages of boiler downtime owing to boiler tube sheet cracking failures. Investigations carried out revealed high stress at the tube-to-tube sheet joint in the boiler fire-side entrance. Tube-to-tube sheet joints at the boiler fire-side entrance had been fabricated by strength welding and without any expansion. The strength welded joint had created undue stress leading to cracking of the weld joint by thermal expansion. A higher quality expanded joint consisting of expanding, flaring and seal welding the fire-side entrance was implemented during the re-tube process. The utility plant has now zero downtime due to boiler tube failure. This article summarizes the description and history of failures with the boiler at the utility plant; investigations and corrective actions carried out; and the present improved condition of the boilers.

Powder metallurgy with hot isostatic pressing (PM-HIP), which enables to densify powders in a furnace at high pressure and temperature is a newly developed manufacturing process for pressure retaining part in nuclear industry. It has advantages such as weld free near-net shape products, improved material properties for castings, short process time, saving in raw material costs, etc. EPRI have conducted several tests such as tensile test, impact test, chemical composition analysis on the manufactured samples for pressure retaining applications.

Oil and gas wells represent a large capital investment. It is imperative that corrosion of well casings be controlled to prevent loss of oil and gas, environmental damage, and personnel hazards, and in order to ensure economical depletion of oil and gas reserve. Wells placed in external corrosive environment shall be protected by appropriate barriers such as additional cemented casing, cathodic protection and coating to assure well casing integrity.

Carbon capture and sequestration (CCS) is gaining greater importance in the industry transition to meet climate goals reducing carbon intensity. As the source of CO2 captured for sequestration widens to many more applications from oil and gas productions, power plants, refineries, chemical plants, steel manufacturing and other industries, the composition of the captured gas stream for sequestration sees various components. Some of the common impurities particularly from combustion processes are carbon monoxide, oxygen, SOx, NOx and others. Understanding the effect of presence of the various chemical species on material limits and maximum tolerance limits are crucial for safe operations of the assets. In one of the recent projects, there was a presence of CO in the CO2 stream, and it was imperative to identify the effect of this on the existing carbon steel pipeline. The pipeline was of X65 steel and fabricated for natural gas transmission. Wet CO-CO2 cracking is a reported degradation mode particularly as the CO concentration increases beyond 200 ppm in the gas phase or at partial pressures above 0.3 bar. This study is a combination of literature review of current state of art with respect to CO-CO2 cracking in carbon steel in presence of impurities and laboratory testing of welded X65 specimens exposed to CO concentration in dense (liquid) phase up to 1000 ppm and also in the presence of small concentrations of oxygen that also replicates some of the expected conditions in the project. The tests clearly indicate that the risk of CO-CO2 cracking is not significant up to the concentrations tested.

Coatings are integral to a corrosion prevention strategy, especially with a multilayered system and cathodic protection. While these systems have redundancies and are designed with extended lifetimes, it is important to understand how each part of the system performs under stress. There are many coating chemistries out there for corrosion prevention, such as liquid epoxies and polyurethanes, but Fusion Bonded Epoxy systems have many favorable properties for scenarios that require the most cost-effective, resilient solution.

Oil and gas operations worldwide are impacted by the presence of microorganisms. A variety of microorganisms can be found in the oilfield, dependent on the type of operation, geology, location, water source and water treatment utilized. Biocides are used in all stages of oil and gas development to control microorganisms and their detrimental impacts on production such as corrosion, biofouling, and souring. A wide number of biocides are used to control microorganisms, ranging from oxidizing biocides that react quickly but leave no residual activity, to preservatives which act slowly, but provide antimicrobial activity for weeks or months at a time. The spectrum of biocides used in oil and gas are covered by several excellent reviews and will not be detailed in this paper.
