Nickel base alloys with high chromium and molybdenum contents are very resistant to chloride-induced localized corrosion, even at relatively high temperatures. These alloys include the Ni-Cr-Mo(W) or “C” family of alloys and the novel Ni-Mo-Cr alloy HYBRID-BC1 (UNS N10362). Alloy 22 (UNS N06022) stands out due to its versatility: chromium and molybdenum contents were selected to optimize its corrosion behavior in oxidizing and reducing conditions. Alloy 625 (UNS N06625) has outstanding thermal ageing resistance and a longer in-service experience. The
The life-cycle of concrete structures used in waste water systems should consider all factors that might cause a structural system to perform unacceptably at any point during its lifetime. This includes the progressive and sustained loss of load capacity caused by operational or environmental factors. In general terms, deterioration can be defined as a loss of structural load capacity with time as a result of the action of external agents causing chemical attacks or material weakening due to these environmental interactions.
Once a coating system has been breached, protection is afforded by the availability of inhibitors at the defect site. The onset of subsequent corrosion, therefore, is a function of inhibitor release rate, the ratio of inhibitor to aggressive ions, and consumption of inhibitor in the vicinity of the defect. The parameters affecting each of these processes must be understood in order to appropriately model the onset of corrosion for either a first principles or an empirical approach. The influence of coating properties and environmental conditions on inhibitor exhaustion is discussed below.
In this paper the performance of a variety of biopolymers and synthetic polymers as calcium phosphate inhibitors is evaluated under a variety of cooling system impurities. For comparison various commercially available phosphonates were also investigated.
Being one of the most applied nickel alloy in the oil and gas industry, the UNS N07718 (Alloy 718) is mainly composed by nickel, chromium, iron, molybdenum, niobium, titanium and aluminum. UNS N07718 is used in the solution annealed and precipitation hardened condition, where a complex microstructure is formed, which is responsible for its very good mechanical properties, as well as its cracking and corrosion resistance.
Inline cathodic protection current mapping is a unique method of assessing a pipeline’s cathodic protection. This is accomplished by measuring the actual current received by the pipeline continuously along the entire pipeline length. Unlike pipe to soil potentials, which can have a great deal of error in them due to forces often beyond our control, the CP mapping tool uses the physical properties of the pipe itself to measure the CP current. The pipe is a very stable part of the circuit, unlike the soil surrounding it.
The following paper will briefly review the origin and development of dehumidification and climate control equipment for the most efficient surface preparation and coatings to surfaces in enclosed spaces. As the needs of the surface preparation and coatings industry evolve, so to do the requirements and ancillary equipment used by field personnel working on these projects.
Metallic coatings as a protective coating are characterized by excellent corrosion protection behavior and show extreme resistance to mechanical loads as well. Pure metallic coatings or duplex systems are already being used successfully in other areas of offshore structures. For example, areas in the tidal water zone, such as boat landings, usually receive a duplex system consisting of thermal spayed coating and a fitting topcoat. Add-on parts are often protected exclusively by a metallic zinc coating. A thermal spray coating in the submerged zone thus represents a logical alternative to the organic topcoat system.
Microbial contamination in the development of unconventional oil and gas formations can cause numerous problems, including formation plugging, microbial induced corrosion, and well souring, all of which can have a negative effect on well productivity and quality of oil and gas. The most common method to control microbial contamination during stimulation of unconventional oil and gas formations is through the use of biocides. Traditional oil and gas biocides such as glutaraldehyde/quaternary ammonium blends struggle to provide effective microbial control under the severe conditions encountered during stimulation of unconventional oil and gas formations.
Cost effective and optimum pigment dispersion is the most important aspect of color and appearance of coatings. Brilliant hues and high chroma are achieved by a perfect pigment dispersion where primary pigment particles are achieved and are well stabilized in the finished paint. The dispersion process is very critical, very time consuming and cost-intensive, and consists of continuous reduction of the pigment agglomerates into smaller size aggregates, and finally into primary particles.
