Standard HDPE pipe is widely used across pipeline infrastructure, but it reaches its limits in high-pressure applications and the increasing costs are threatening projects globally.
MaxDR® High-Pressure Composite Poly Pipe
MaxDR® - The Strength of Composite with the Easy of Poly™
To handle higher operating pressures, standard HDPE requires thicker walls (DR ratings), which drives up material costs, increases weight, slows installation, and adds complexity in the field. For many operators, this creates a tradeoff between performance, cost, and constructability.
MaxDR® was developed to eliminate that tradeoff.
MaxDR from Composite Piping Technology 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 equivalent HDPE pipe—while using less material, reducing installation time, and lowering total project cost.
The result: a true alternative to HDPE pipe for high-pressure pipeline applications.
- Delivers 2-3x greater pressure performance compared to equivalent ID and pressure rated HDPE.
- Available in 12” to 24” diameters.
- Safely works with operating pressures of 350, 550 and 750 psi.
- No-leak fused connections for a wide range of gas, liquids, and slurries including highly corrosive using standard HDPE fusing equipment.
- Manufactured to ASTM standards applicable to traditional HDPE 4710 and FRE/GRE pipe.
- Embedded RFID tags support better traceability.
MaxDR has the same properties as standard HDPE poly pipe, so you can use the same tools and engineering standards for design, transport, fusing and installation.
A Measurable Difference in Performance and Value™
As a lighter, higher-pressure pipe for the same application, MaxDR is a better HDPE pipe alternative and delivers:
- Lower installation costs.
- Decreased operating costs.
- Significantly reduced carbon intensity.
- No leak fusion joint.
- Improved safety profile.

A Sustainable Solution with the Lowest Total Cost of Ownership
MaxDR fusible composite poly pipe delivers several quantifiable benefits over other HDPE, fiberglass and steel pipe including:
Lower Capital Expense
MaxDR weighs significantly less than standard poly, fiberglass or steel pipe, making it less expensive and easier to handle.
Higher Pressure Performance
Delivers higher pressure ratings and capacity compared to equivalent ID poly.
Faster Fusing
Fuses faster than equivalent ID/PSI poly-pipe, speeding construction and reducing installation costs.
Retains HDPE Properties
MaxDR utilizes most HDPE 4710 pipe material characteristics.
Lower Operating Costs
When used in place of steel pipe, no expensive cathodic protection is needed.
No Operational Changes
Utilizes the same fusing equipment and installation procedures as traditional poly pipe.
Improved Safety
Compared to poly pipe with the same ID, MaxDR provides a 4-to-1 safety design factor.
Environmentally Friendly
ESG benefits including lower carbon-intensity score for pipe, installation and operations.
