Developing the first high-pressure, fusible composite HDPE poly pipe is no easy feat, but that is exactly what we are doing at Composite Piping Technology.
An important milestone in the process is the D1599 Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings, established by the American Society for Testing Materials (ASTM), commonly known as the “Quick Burst” test.
The ASTM D1599 test method “…establishes the short-term hydraulic failure pressure of thermoplastic pipe, tubing and fittings, and reinforced thermosetting pipe, and reinforced thermoplastic pipe.” The test involves subjecting multiple joints of pipe to a hydraulic pressure test to simulate field conditions and determine the Design Safety Factor.
ASTM D1599: To Rate Our Pipes, We Had to Break Them!
We subjected our MaxDR™ 350 pipe to the D1599 Quick Burst test to assess the targeted 4:1 Design Safety Factor. The video below shows the resiliency of MaxDR 350 during a test session.
The test simulated how MaxDR 350 would stand up to pressures far exceeding those likely to be encountered in operational service in a buried or restrained environment.
Result:
The 12″ MaxDR™ pipe exceeded the Design Safety Factor goal of 4:1 and is rated for 350 psi service based on repeatable QC quick bursts at over 1400 psi.
MaxDR™ High-Pressure Fusible Composite Poly Pipe
MaxDR from Composite Piping Technology (CPT) is the first large diameter, fusible composite poly pipe reinforced by multiple layers of fiberglass cohesively bonded to the HDPE core pipe. MaxDR offers pipeline designers, builders and operators all the benefits of HDPE poly pipe with the strength of composite materials.
The table below compares MaxDR 350 to its standard HDPE poly pipe equivalent.
Key Features of MaxDR Include:
- Large diameters.Available in diameters ranging from 12″ to 24″.
- Enhanced pressure performance.Delivers 2-3x greater pressure performance while remaining lightweight and strong.
- High-pressure applications.Available for applications of 350, 550 and 750 psi service, dramatically expanding the performance envelope of lightweight, fusible HDPE poly pipe.
- MaxDR joints are fused together using existing HDPE fusing equipment.
- Corrosion resistant. Suitable for transporting highly corrosive gases, liquids and slurries.
- Compliance with standards.Manufactured to ASTM and API standards applicable to traditional HDPE 4710 pipe.
- Full traceability.Embedded with RFID tags aids digital traceability.
MaxDR Benefits
MaxDR offers A Material Difference in Performance and Value™. As a lighter, less expensive pipe for the same application, MaxDR composite poly pipe delivers these benefits:
- Use poly pipe where it has never been used before. MaxDR enables the use of lightweight, easy to use, durable poly pipe in applications where ordinary HDPE cannot due to pressure constraints.
- Lower installation and capital costs. MaxDR is substantially lighter than alternative steel pipes for higher-pressure applications, reducing transportation, handling and installation costs. The ability to use existing poly pipe fusing equipment enables faster installation.
- Decreased operating cost. Leak-free operation eliminates spills and the need for costly cathodic protection and anti-corrosion chemicals.
- Reduced carbon intensity. Composite pipes use fewer resources, promoting sustainability and resource conservation.
- No leak fusion joint. Easy to use and MaxDR segments are joined using existing HDPE fusing technology for a leak-free connection, mitigating risk and improving environmental performance.
- Easy to use. Retains the properties of HDPE, making them familiar and user-friendly.
Summary
MaxDR is the first high-pressure, large diameter fusible composite HDPE poly pipe, opening the door to new possibilities for pipeline designers, builders and operators. MaxDR offers users in Oil & Gas, Industrial & Mining, Water & Wastewater and CO2 gathering and processing sectors a sustainable solution with the lowest total cost of ownership.
