Want to know how you can become more active in NACE? There are many opportunities for NACE members to volunteer, and the technical committees offer many benefits such as having an impact on industry standards, developing a network of peers, and enhancing your career.
Safety, function, and service life should be a part of every project. To address these parameters, consideration must be given to design, choice of materials, construction methods, active and passive surface protection, and other parameters.
NACE International’s International Measures of Prevention, Application, and Economics of Corrosion (IMPACT) study is nearing completion and will be released in March 2016. A segment of the report focuses on the Corrosion Management System Framework and how a company can incorporate one into its own program.
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.
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.
A combined-cycle power plant in Asia utilizes seawater as auxiliary cooling water (ACW). The carbon steel ACW pipe was lined with coal tar epoxy. After six months in operation, the ACW pipe started leaking due to internal corrosion. A retrofit impressed current cathodic protection (ICCP) system was installed.
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.
During the service life of a pipeline, the coating has to maintain its integrity under operating environments and in the presence of cathodic protection (CP). A coating that exposes bare metal areas renders the pipe surface susceptible to corroding species, and a functional CP system will be required. This article discusses the basic principles of corrosion protection with coatings and CP, and the attributes of an effective pipeline coating.
NACE International’s new IMPACT emphasizes how to integrate corrosion technology with management systems to optimize corrosion decisions. For findings related to the pipeline industry, three IMPACT study and pipeline experts answer a series of questions.
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.
Structures such as steel bulkheads, steel piles supporting piers or wharfs, offshore drilling platforms, and other similar structures may be cathodically protected with either sacrificial galvanic anode systems or impressed current systems.
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.
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 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.
