Zinc-rich coated rail, which protects in the most corrosive of environments, is being supplied in longer lengths and is seen as ideal for track environments, such as those in tunnels.
Generally speaking, galvanized steel can last for many years in nonaggressive environments, and typically does an excellent job of protecting steel when the structure is located in moderately corrosive environments where oxidizing conditions prevail.
A novel approach is presented regarding corrosion assessment and cathodic prevention of foundations for electric transmission towers in the Persian Gulf region.
Some unique capabilities of cathodic protection design methodology are showcased with grillage-type foundations for power transmission structures.
One of the areas where cathodic protection is commonly applied to marine structures for corrosion protection is the steel piling systems on jetties and piers. This article discusses the design and implementation of CP on a newly constructed jetty in Surabaya, Indonesia.
Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.
A major U.S. university is using funding from Phillips 66 to develop a new outdoor pipeline integrity lab, which will include buried pipe with an active rectifier to simulate real-life activities.
As pipelines age, it is important to verify the effectiveness of the coating and cathodic protection systems that protect them against external corrosion, and implement remedial actions if necessary.
A novel, organic zinc-rich primer coating technology relies on a combination of zinc dust, hollow glass spheres, and a proprietary activator to provide cathodic protection with greatly improved mechanical properties (crack resistance) and adhesion.
There is a need at many remote oil and gas field sites for data typically collected by specialized sensors. To meet this need, a remote CP monitoring platform was developed that combines a dedicated two-channel CP rectifier/test station monitoring device and a dedicated two-channel sensor/transducer monitoring device into one unit.
Due to the high carbon dioxide (CO2) and chloride content in natural gas produced by a gas field in Western China, a high-performance duplex stainless steel was chosen for gas gathering and transmission piping in this area.
Unmanned aerial vehicles (UAVs), are being utilized more and more in various industries to safely and efficiently inspect critical assets and infrastructure that would otherwise be difficult to access.
One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.
Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.
It is becoming more common for crude oil or gas pipelines to share their rights-of-way with high-voltage alternating current (AC) power lines. The integrity of AC mitigation facilities is crucial for personnel safety and continued operation of pipelines with effective cathodic protection.
