Easy to Install Tank CP System – No Cutting, No Splicing, No Welding
We’re excited to share this aerial drone view of a recent tank CP installation starring MATCOR’s exclusive Tank Ring Anode™ System. Superior to grid anode systems for tank bottom cathodic protection, the Tank Ring Anode System is factory assembled in concentric rings sized for your tank and shipped ready for quick installation.
Cathodic Protection Anode Designed Specifically for Tank Bottom Replacement Applications
MATCOR was recently issued US Patent No. 9,410,253 for its SPL-SandAnode, an impressed current linear anode that prevents corrosion of above ground storage tank bottoms (ASTs). Invented by Glenn Shreffler, executive vice president of engineering for MATCOR, the SPL-SandAnode is the only impressed current linear anode designed specifically for tank bottom replacement projects. These applications typically have six inches (150 mm) or less of sand where the anode is to be installed.
The recommended cathodic protection system for most ASTs is a tank ring anode system that utilizes linear anodes in a concentric ring configuration. However, when the clearance between the tank bottom and anode is less than 6-inches (150 mm), the SPL-SandAnode is used, either in the concentric ring configuration or in parallel linear lengths. The prepackaged linear anode with a sand backfill, in lieu of calcined coke, allows the anode to be simply laid out on the foundation while easily maintaining the maximum separation distance of the anode to the tank bottom.
The SPL-SandAnode is one of MATCOR’s SPL™ Anode Series, a complete line of flexible impressed current linear anodes utilizing MMO anode technology to support a broad range of cathodic protection applications. Advantages of MATCOR’s linear anodes include:
External corrosion of above ground storage tank (AST) bottoms is a significant problem for tank owners. Corrosion professionals tasked with protecting these structures should consider multiple factors. One thing is clear: proper installation of an impressed current tank bottom cathodic protection system plays an important role in reducing corrosion and extending the service life of the tank bottom.

As you watch the evening news or pick up your daily paper you will very likely read about the new Missile Defense Shield in Romania that came on line this week. The Russian response has been loud and indignant. This story will be all over the evening news, cable channels and newspapers.
But did you know that the Deveselu facility in Romania has a MATCOR Cathodic Protection system protecting the buried piping and process tanks? MATCOR VP of engineering Glenn Shreffler made three trips to the site during its construction. So when you watch the evening news and they discuss the “controversial” missile defense base in Romania, we are proud that MATCOR anode systems are hard at work protecting the assets that protect our NATO allies.

Iron Gopher® Impressed Current Linear Anode System designed for horizontal directional drilling (HDD) is installed beneath an above ground storage tank (AST)
Chalfont, PA – MATCOR, Inc. the trusted full-service provider of proprietary cathodic protection products, systems, and corrosion engineering solutions recently released a video showing the installation of the company’s Iron Gopher impressed current linear anode system at the site of an above ground storage tank in Texas.
Trenching to install cathodic protection systems may not be feasible for applications such as cross country pipelines, congested industrial environments and under above ground storage tanks. For these horizontal directional drilling applications, a linear anode with superior mechanical strength is required. The Iron Gopher with Kynex® technology is the only impressed current linear anode designed specifically for cathodic protection in horizontal directional drilling applications.
“As another example, Colonial Pipeline installed several thousand feet of our Iron Gopher® linear anode at an HDD project in NE Georgia,” said Ted Huck, VP of Sales for MATCOR. “With its unique design and greatly increased strength, Iron Gopher is superior to anything seen in the market for cathodic protection in HDD applications.”
Design a Detailed Tank Ring Anode System™ for an Above Ground Storage Tank in Seconds with MATCOR’s Web Application.
Chalfont, PA – August 28, 2014, MATCOR, Inc., the trusted full-service provider of proprietary cathodic protection products, systems and corrosion engineering solutions, launched a valuable, timesaving web application that enables corrosion professionals to design a cathodic protection system for their above ground storage tanks (ASTs) in seconds.
“This web-based app makes it easy for our customers to design tank cathodic protection systems and enables rapid turnaround for a quote,” says Douglas Fastuca, President of MATCOR. “An ease-of-use and quick response philosophy is consistent with MATCOR’s Tank Ring Anode System, which is very easy and safe to install within a few hours. With this productivity tool MATCOR continues its tradition of innovation and enabling creative cathodic protection solutions.”
The MATCOR Tank Ring Anode System App is available at matcor.com/tankring. The user enters specifications for their above ground storage tank and installation environment, and the app delivers detailed tank ring anode cathodic protection design specifications. MATCOR will then quickly quote and manufacture an accurate, reliable impressed current cathodic protection system, which utilizes patented Kynex® waterproof connection technology.
The factory-assembled MATCOR Tank Ring Anode System is fast and easy to install with no field anode assembly required. A small crew can install most systems in under two hours with no welding, hot permit, splicing of anode sections or special backfill required. MATCOR offers Tank Ring Anode Systems for new and retrofit tanks.
In January 2014, above ground storage tanks (ASTs) containing the chemical 4-methylcyclohexanemethanol (MCHM) was released into Elk River in West Virginia. The leaks, which cursory reports believe to be the likely the result of corrosion, could have been avoided by implementing proper cathodic protection systems.
The facility, operated by Freedom Industries, containing the chemical was located in Charleston, West Virginia. Recently, federal investigators discovered that the spill might have originated from more than one tank and could account for up to 10,000 gallons of MCHM.
This catastrophe, which left the 300,000 residents across nine West Virginia counties without potable water, could have been avoided by taking proper precautions.
The spill is currently being attributed to corrosion in the above ground storage tanks that held the MCHM. Corrosion is a serious and persistent concern for ASTs, which must withstand the elements.
“Above ground storage tanks pose a specific set of problems when it comes to corrosion prevention. The evidence collected by several federal agencies suggests that this hazardous leak was the result of a tank bottom leak,” said Ted Huck, vice president, international sales and practice lead – plants and facilities at MATCOR. “The leak was caused by the corrosion of the tank bottom due to contact of the external tank plate with the soil.
“The resulting soil-side hole could have been prevented by MATCOR’s patented cathodic protection systems. While cathodic protection systems are commonly used in oil and gas storage tanks, they are not mandated and there are tanks across the country that do not have cathodic protection systems installed to protect tank bottoms from leaking.”
Cathodic protection systems are critical for preventing corrosion in ASTs.

The soil-side hole that resulted in the released chemical is a common problem among ASTs. MATOR has developed a reliable protection system for ASTs which uses our unique SPL-Anode system and patented Kynex® technology.
