Cathodic Protection Construction and Inflation

How Today’s Supply Chain Issues Affect Our Industry

For over a decade both the consumer and construction worlds have enjoyed very stable pricing with modest annual increases. 2021 is a very different picture. Suppliers are dealing with supply chain issues and price spikes. These increases far exceed the 2-3% we typically see for cathodic protection construction projects.

Cathodic Protection Construction

In today’s environment, manufacturers and service providers deal with this uncertainty by providing quotes with very limited duration. In some cases quotes are only valid for a few days. This is a far cry from the 30- to 90-day validity once common in the industry.

The challenge for everyone in the industry is the lag time between the budgeting phase of a project and the purchase of materials. For major projects, the planning, permitting and pre-construction phases of a project can take years.

It is important to note that the inflation figures we see quoted in the news are typically “consumer price index.” These inflation figures run about half of the less reported “producer price index,” which more accurately captures manufacturers’ material costs.

When you hear that the core inflation rate is 4 or 5%, you can reasonably expect that material costs are rising at 8-10%.

What can companies performing cathodic protection construction do to manage project budgets in an inflationary environment?

  • Take action quickly. Time is money. The longer you wait to purchase materials and services, the more you can expect to pay for them. Once you have approval for a cathodic protection project, order the key materials quickly.
  • Share the inflation risks fairly with your suppliers and contractors. Holding a contractor to yesterday’s prices is unrealistic and unsustainable. That contractor will be looking for ways to cut costs. And they may accomplish it by cutting quality, reducing the scope, substituting cheaper materials, or demanding change orders at every opportunity. This type of relationship does not benefit any of the parties.
  • Consider ordering materials separately from construction. This applies especially to materials you can pre-stage, have long storage life, or repurpose easily for other projects.
  • Be realistic when providing project schedules. Haven’t nailed down all the landowner or permit issues? Then don’t tell your suppliers and contractors that you expect the project to kick off next month.

What is MATCOR doing to address issues related to cathodic protection construction projects?

As a supplier of cathodic protection materials and construction services, MATCOR takes a team approach. We are eager to engage with customers and work together to minimize impacts from supply chain disruptions and price increases.

Stretch Your Cathodic Protection Budget

Now is a great time to think about stretching your 2021 budget and getting a jump start on 2022.

Days are growing shorter and long summer days are turning to dark winter days. This makes it difficult to spend the last of your CP budget dollars on completed construction projects this year.

Equipment and crews are generally already booked. However, MATCOR and our sister company JA Electronics can still help you spend your 2021 budget dollars productively.

We still have manufacturing capacity for this year. Purchasing cathodic protection anodes, rectifiers and other CP components now can help use up those remaining funds while also giving you a head start on 2022 projects.

Get Your Act Together

The first quarter is often a slower quarter in the construction business since companies are still planning their 2022 CP spend.

But what if you had your act together and were ready to start cathodic protection construction projects earlier in the year?

Well, we at MATCOR are eager to talk to you about special off-season pricing that we can offer for Q1 projects. Are you in a position to buy materials in Q4 and install them in Q1 of 2022? We can load share our construction capacity and provide off-peak pricing, making it very attractive indeed to have your act together.

Corrosion Control for Water Treatment Facilities

We recently received an inquiry on our cathodic protection FAQ asking about “the best corrosion control protection for above-ground steel tanks treating wastewater.” Well, corrosion control for water treatment facilities is such an interesting and relevant topic that it warrants an expanded response, so here goes.

Wastewater treatment facilities generally have many tanks storing and processing wastewater through multiple treatment stages. These tanks and vessels are subject to corrosion, and there are a range of strategies to extend their service life.

Corrosion control for water treatment facilities' tanks and vessels

Corrosion Protection Strategies for Water Treatment Tanks and Vessels

These strategies fall into four broad categories: material selection, chemical treatment, coatings, and cathodic protection.

Wastewater Tank and Vessel Material Selection

From a material selection perspective, most wastewater treatment vessels are carbon steel. However, some chemical wastewater treatment facilities may require more “exotic” materials early in the treatment process due to the wastewater feed material.

Once the wastewater feed material has been treated and/or neutralized, the remaining process tanks and vessels are likely to be carbon steel construction.

Corrosion Protection via Chemical Treatment

The next broad category of corrosion control strategies is chemical treatment. While chemical treatment is an integral part of the wastewater process, specifically in terms of pH neutralization and chlorination processes, the chemical treatment performed during the treatment of wastewater is not typically intended to control corrosion.

One area where chemical treatment might be a viable corrosion control strategy is with the use of vapor corrosion inhibitors (VCIs) to protect the underside of steel storage tanks.

Coatings for Corrosion Control of Water Treatment Tanks and Vessels

The appropriate selection and application of coatings is a key corrosion control strategy for wastewater treatment facilities.

Coatings are particularly effective in protecting carbon steel structures including above ground piping, atmospheric external tank shells, wetted internal tank walls, submerged steel structures, and many other structures.

Coatings, however, are not perfect and they have a finite life. For structures that are easy to access, inspecting and re-coating are often the sole means applied to protect against corrosion.

Cathodic Protection

The final corrosion mitigation strategy that can be effectively employed to protect wastewater tanks and process vessels is the use of cathodic protection.

Cathodic protection can be used to protect bare steel structures, or in conjunction with coatings.

There are two basic types of cathodic protection, galvanic (often termed sacrificial) and impressed current. Some typical cathodic protection applications in wastewater treatment facilities include protecting the soil side bottoms of large above ground storage tanks and vessels, and protecting the internal wetted surfaces of tanks and process vessels including rotating equipment such as rakes and wiper arms.

MATCOR has extensive experience designing, supplying and installing cathodic protection systems for wastewater tanks and process equipment, including several proprietary impressed current anode systems that are especially well suited for these applications.

Linear Anodes for Hard-to-Reach Places [Rusty Talks]

Rusty and Josh Johnston chat about a recent project and case study involving the use of linear anodes for hard to reach places.


This month, MATCOR exhibited at the AMPP Central Area Conference held in Kansas City. MATCOR’s Mr. Josh Johnston, along with Mr. Chad Farris of Energy Transfer, jointly presented a paper—a case story using linear anodes as a shallow horizontal anode bed installed along two pipelines in central Kansas.

Rusty: Josh, tell us how it felt to finally be in a real-life conference interacting with people in person after the last year and half of cancelled conferences and virtual conferences.

Josh: It is always great to get to interact with our friends and industry colleagues, clients, suppliers and competitors to share information and discuss the challenges that our industry faces—especially given the events of the past couple of years. Presenting this paper was a great opportunity to highlight the use of linear anodes to protect hard to reach areas on older pipelines.

Rusty: Can you describe the problem that you covered in your presentation?

Josh: Energy Transfer had two older pipelines that were not meeting criteria in a rural location. As is typical in a lot of pipeline cathodic protection applications, the pipelines were being protected by impressed current anodes located at road crossings where power was readily available. The roads ran parallel to each other and were located one mile apart. The pipeline traversed these two roads and the area in between was mostly farmland. As a result of the age and coating condition, the shallow horizontal anode beds, located at the road crossings, were not able to project much more than a ¼ mile from each end, leaving approximately ½ mile in the center under protected. This was clearly identifiable in the close interval survey (CIS) data.Linear Anodes for Hard to Reach Places

Rusty: Couldn’t they simply increase the current output of the existing shallow ground beds at each end of the pipeline to drive more current to the center section in between?

Josh: They tried that approach, and it did not work, raising concerns that driving excessive current onto these older pipelines could actually make the situation worse by further disbanding any coating close to the existing ground beds.

Rusty: So where did MATCOR come into this project

Josh: MATCOR proposed linear anodes be installed parallel to each of the pipelines in the area between the two roads. MATCOR developed the very first MMO (mixed metal oxide) linear anodes over 30 years ago and we have the most experience designing linear anode CP systems.

Rusty: So it sounds easy, you take a couple of ½ mile segments of linear anode, trench them in parallel to pipeline and run a couple of long extension cord cables back to the road where there is power.

Josh: Well it does sound easy; however, in practice it is critical that any linear anode design carefully addresses voltage drop, and that the power feed cabling is configured so that each anode segment output is balanced. If this is not engineered properly, you could have a large disparity in the voltage being applied on one end of the anode segment relative to the other end. This would result in a very uneven distribution of current. Discussing the design considerations for the power feed cabling was the primary focus of this presentation.

Rusty: So how did it work out?

Josh: MATCOR was able to use some creative cabling analysis and routing to assure that the voltage difference from one end of an anode segment to the other was no more than a 10% variance. The post installation and commissioning CIS data delivered an outstanding current distribution.

Rusty: Thanks for providing a very quick overview of your presentation—any final thoughts or comments?

Josh: When designed properly, linear anodes can be a real problem-solving solution for older pipelines with current distribution and attenuation issues.

Oh yeah, Kansas City BBQ still rocks!

6 Things to Look for in a CP Rectifier

The AC/DC transformer cathodic protection rectifier is a relatively simple and highly reliable piece of equipment that is a proven workhorse in the cathodic protection industry.

In the short time since our parent company BrandSafway acquired JA Electronics, we’ve learned a lot from them about how they build the best CP rectifier in the corrosion industry.

Best CP Rectifier

A lot of little things add up to a big difference between a merely good CP rectifier or a best in class rectifier.

And these little things don’t really add to the unit’s cost. In some cases, they are both best in class and lower cost.

JA Electronics recently published an article entitled Building the Best Cathodic Protection Rectifier. Here are the top 6 things they recommend if you want the best cathodic protection rectifier at the best price:

  1. A marine grade aluminum case
  2. Color coded engraving and wiring
  3. Thoughtful layout for ease of use and long life
  4. Left side maintenance door for simplified access
  5. A modular bridge diode assembly for easy troubleshooting
  6. Brass solder lugs for reliability

VCI for Tank Bottom Protection

The American Petroleum Institute (API) recently issued a landmark technical report regarding vapor corrosion inhibitor (VCI) use for storage tank bottom corrosion protection (API TR 655).

VCI has been promoted as a technology for use under above-ground storage tanks for the past decade. This effort recently received a big boost with the American Petroleum Institute’s publication of its long-awaited technical report on VCI.

Vapor corrosion inhibitor technology for tank bottom corrosion protection gets boost from API technical report.

API TR 655 Vapor Corrosion Inhibitors for Storage Tanks; First Edition; April 2021 provides the first set of guidelines for VCI issued by an internationally recognized non-governmental technical standards organization.

MATCOR has been an early adopter of VCI technology as we believe that it can be an important and effective component in a corrosion prevention program for tank bottoms. We have partnered with Zerust to be an authorized distributor and installer of VCI products for tank and other applications.

We are excited that API has led the way on recognizing VCI technology, and we would expect that other organizations–AMPP for one–will adopt similar guidelines and recommendations.

For a more detailed review of the technical report, visit our VCI partner company Zerust’s summary at the link below:
