CPT’s MaxDR-si Pipe Chosen for High-Pressure Tailings Pipeline at Brazilian Gold Mine
A Landmark First for MaxDR in Surface Mine Installation
Composite Piping Technology (CPT) today announced a series of company milestones with the selection of its MaxDR-si™ large-diameter, fusible composite reinforced HDPE surface installed (“si”) pipe for a gold mine tailings pipeline in Brazil. The project marks CPT’s first international project, its first shipment inside intermodal containers, its first mine application, and its first surface installation, establishing MaxDR pipe as a solution for demanding mining environments around the globe.
The project required 9,800 feet of MaxDR-si 20-inch pipe operating at the product’s full 350 PSI pressure rating. The pipeline will transport tailings slurry directly from the mine’s processing operation to its tailings pond, running at maximum rated pressure.
Because the pipe was shipped overseas in standard intermodal containers, CPT manufactured 39-foot joint lengths, instead of the standard 50-foot joint, to maximize shipping efficiency while ensuring seamless field installation. The result was a purpose-engineered supply chain that delivered full-length pipe to the remote Brazilian mine site located in the Amazon without compromise to product integrity or project schedule.
Importantly, CPT provided comprehensive on-site training, ensuring all personnel were fully prepared to handle, install, and fuse MaxDR pipe joints correctly, efficiently and safely. To support the project, CPT translated its installation manuals and training materials from English into Portuguese and delivered hands-on instruction in the field. The successful transfer of technical knowledge across a language barrier underscores CPT’s commitment to supporting its customers wherever they operate.
B.G. Clark, President and CEO, Composite Piping Technology, said, “This project represents a major milestone for CPT and further validates the growing market acceptance of the MaxDR product line. It marks several important firsts for our company – our first international deployment, our first mine application, and our first surface installation. I am especially proud of our team’s ability to produce a non-standard joint length that could be safely and cost-effectively shipped to Brazil in standard containers while meeting the project’s demanding reliability and performance requirements.
“More importantly, this project showcases the engineering expertise, adaptability, and customer commitment that define CPT. From custom product design and international logistics to field training and installation support, our team successfully executed a complex high-pressure infrastructure project across continents, languages, and operating environments. The result is a proven solution that demonstrates MaxDR’s ability to perform in some of the world’s most demanding industrial applications.”
“This project demonstrates CPT’s ability to support mining operators anywhere in the world”, notes Steve Bagley, CPT’s Chief Operating Officer. To ensure a successful installation, our team provided hands-on instruction that qualified the local crew to install MaxDR to CPT’s standards from day one. By transferring technical knowledge and building local expertise, we empowered the customer to install and operate the system with confidence.”
“South America is one of the most important growth markets for mining infrastructure, and this project establishes CPT as a reliable and capable partner for operators seeking safe, reliable, and cost-effective high-pressure tailings and slurry transportation solutions. It demonstrates not only what MaxDR can do as a product, but what CPT can deliver as a global provider of piping solutions,” said Clark.
MaxDR-si for Surface Installation – Perfect for Tailings Pipelines
MaxDR-si is engineered to perform in difficult terrain, harsh climates, and environmentally sensitive areas where digging trenches and burying pipelines is not a standard operating procedure or is not an option.
MaxDR-si is a high-pressure, large-diameter, fusible composite pipe built on an HDPE core and reinforced with advanced composite materials. It delivers 2–3x the pressure performance of core HDPE pipe, while using less material than equivalent ID and pressure rated HDPE, reducing installation time, and lowering total project cost. A MaxDR-si 350 joint weighs approximately half as much as a comparable ID DR7 poly pipe joint. Lighter pipe sections simplify logistics:
- Haul nearly double the length on a truck
- Reduced weight-rated lifting equipment
- Improved crew efficiency and safety
Because MaxDR retains the full material properties of HDPE, it provides inherent resistance to H₂S, CO₂, chlorides, produced water, crude oil, and corrosive/abrasive slurries — without cathodic protection systems, without coatings, and without the corrosion monitoring programs that steel-based systems require.
MaxDR-SI’s fused joints eliminate the corrosion vulnerabilities of steel and fiberglass pipe from mechanical seals, joints, flanges, gaskets, or bolts.
The successful completion of this project positions CPT for continued expansion across the global mining market, where infrastructure demand for high-pressure slurry transport continues to grow alongside the region’s expanding gold and base metals sectors.
