A collection of antique instruments illustrates the rich history of the East Bay Municipal Utility District’s corrosion department.

The North Cormorant oil and gas the platform is more than 35 years old, it still serves as a critical hub for major fields in the area. Several subsea surveys over the last several years, however, indicated a reduction in its corrosion protection via CP.
An impressed current cathodic protection system was installed and commissioned on several steel-reinforced concrete structures that support two of the Port of Brisbane’s wharves.
Once construction has commenced, several tasks are required to ensure a safe and successful pipeline installation with effective cathodic protection and mitigation of interfering current.
Cathodic protection has been a recognized technology for buried metallic pipelines, but hasn’t been widely used in the water industry.
Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.
Alaska is home to many distinct environments, with each presenting its own challenges when designing for corrosion control.
Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.
New instrumentation technology in the pipeline survey industry has helped produce and deliver results for the pipeline surveyor, analyst, and operator.
The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.
The primary cause of deterioration of reinforced concrete structures is corrosion of the steel reinforcing bars due to chlorides.
Recent field experiments demonstrated that a cathodically protected perforated monopile structure could create an environment with more favorable corrosion mitigation, air quality, and water chemistry compared to a sealed structure. A newly designed perforated offshore monopile system could help mitigate corrosion within the often flooded interiors of offshore wind turbine support structures.
A new method has been developed to allow for cathodic protection of the upper/new tank bottom in a double bottom tank.
For equipment where coatings are the primary method of corrosion prevention, cathodic protection (CP) can provide a secondary method of protection to areas with coating damage or poor coverage.
