Thermite Welding Components

Thermite (exothermic) welding creates permanent, low-resistance cable-to-structure connections—bonding test leads, anode cables, and rectifier connections directly to steel. It’s the more commonly specified connection method in United States specifications.

Why MATCOR Materials?

MATCOR engineers and manufactures proprietary cathodic protection products in the USA, combining proven field performance with the quality systems and supply chain control that critical infrastructure demands.

Made in the USA, Built for the Field

Proprietary products manufactured in-house with millions of documented operating hours and reliable domestic supply chain control.

Engineered To Perform, Not Just Comply

Products designed by our own corrosion engineers to solve real-world problems, not just meet spec.

Proven Quality Systems

ISO 9001:2015 certified manufacturing with structured quality control and built-in continuous improvement processes.

Backed by Global Resources

The specialized expertise of a corrosion engineering company combined with the systems and oversight of a $6B global industrial services organization.

From application review to delivery and field support, getting the right CP and AC mitigation materials is an engineering decision—not just a purchase. Here’s what working with MATCOR looks like.

AC Interference Mitigation

MATCOR technicians visit your site to collect the electrical transmission, pipeline, and soil resistivity data needed to evaluate fault current and induced AC corrosion risks and identify safety hazards per the latest NACE and industry standards. This field data feeds MATCOR’s AC modeling process, supporting effective AC mitigation system design.

AC Mitigation Grounding Installation

Grounding systems are a critical component of many AC mitigation systems. MATCOR installs AC mitigation grounding systems designed to safely dissipate induced AC current and help protect both personnel and pipeline infrastructure.

AC Modeling

AC interference modeling uses sophisticated software to analyze safety and corrosion risks — step-touch potential, induced AC, and shorted or fault conditions — for pipelines sharing right-of-way with overhead electrical transmission lines. MATCOR provides field data collection and complete AC modeling and analysis to determine interference risks and design the right AC mitigation system.
Decoupler Installation

Decoupler Installation

Decouplers play an important role in AC mitigation systems by providing AC fault and lightning protection while maintaining cathodic protection system performance. MATCOR installs a variety of decoupling devices as part of both new construction and retrofit AC mitigation projects.
