What is CNPS High-Pressure RTP Pipe?
CNPS is the manufacturer of Reinforced Thermoplastic Composite Pipe (RTP Pipe)—a new three-layer structure designed specifically for oil, gas, and industrial transportation.RTP Pipe addresses the challenges of traditional steel pipe, including corrosion, installation difficulties, and a short lifespan.
We use an HDPE liner to withstand a variety of chemical media. A glass fiber, aramid, or steel wire reinforcement layer provides a high-pressure bearing capacity of 32 MPa. Whether it’s handling acidic wells containing H₂S or transporting high-concentration CO₂, our RTP pipes offer reliable service for over 20 years. This reduces joints, leaks, and construction times for our customers, ultimately achieving lower total costs, higher uptime, and safer deployments.
Choosing CNPS means choosing an experienced global partner focused on composite solutions.

RTP Performance by Critical Metric
Whether you’re tackling corrosive CO₂ pipelines in the desert or multiphase flowlines offshore, CNPS RTP Pipe delivers quantified advantages that translate directly into reduced CAPEX and OPEX.
Handles 32 MPa internal pressure without metal fatigue, maintaining full hoop strength for 20 years.
Non-metallic liner and jacket eradicate internal rust, ending costly inhibitor programs.
Up to 1 km per reel allows trenchless pull-ins and 70 % faster installation.
Lightweight coils cut transport costs and shrink joint count, lowering leaks and repairs.
Customizable CNPS RTP Pipe for Your Field
From 2-inch sweet-service flowlines to 6-inch aramid-reinforced water-injection mains, CNPS tailors liner resins, reinforcement fibres, and jacket colours to your exact process conditions and local regulations—delivered on site-specific coil lengths to cut waste and logistics.
Install Faster with CNPS RTP Pipe
Spoolable reels cut joint count , minimizing hot work, permits, and weather delays. CNPS RTP Pipe weighs a fraction of steel, so smaller crews with lighter equipment cover longer routes per shift. Fewer tie-ins accelerate hydrotesting and get production online sooner. Pre-fabricated terminations further speed tie-ins.
Why Choose CNPS for Composite Piping
CNPS delivers complete RTP systems—not just pipes. Our engineers specify classes, fittings, and accessories, then support training, QA, and commissioning. Global manufacturing and ISO 9001 processes ensure consistent quality and on-time delivery. Pre-qualified contractors and rapid reel logistics shorten installation windows, while responsive after-sales service safeguards uptime throughout operations.
Standard designs handle 32 MPa (320 bar) at 23 °C, with higher ratings available on request.
Minimum bend radius is 15 × OD for dynamic pulls and as low as 10 × OD for static placements, enabling route optimisation around obstacles.
No—its all-polymer fluid path eliminates galvanic and CO₂/H₂S corrosion, removing the need for costly chemical dosing programs.
