Reinforced Thermoplastic Pipe (RTP) technology has emerged as a transformative solution in the oil and gas industry, offering a compelling alternative to traditional steel pipelines for high-pressure fluid transmission. The 4-10 inch RTP tape winding production line represents a complete, integrated manufacturing system engineered specifically for the continuous production of fully bonded, spoolable RTP pipes ranging from 114mm to 273mm in diameter.
This advanced production line bridges the critical gap between the corrosion resistance of plastic pipes and the structural strength of steel pipes, delivering a high-performance engineering solution for the most demanding oil and gas applications.

The 4-10 inch RTP tape winding production line integrates multiple core modules into a seamless continuous manufacturing process:
Inner Pipe Extruder: Single screw extruder with custom screw design for HDPE/PP/PA materials
Tape Winding Unit: Multiple units optional (2–16 heads) with automatic constant tension control
Outer Sheath Extruder: Single screw extruder for HDPE/PP protective layer
Cooling System: Spray cooling tank with vacuum sizing
Haul-off Unit: Caterpillar belt type with servo motor control
Winder: Automatic coil winder for spoolable pipe output
Control System: PLC full automation with touch screen HMI and optional remote monitoring
The complete production process encompasses four key stages: inner pipe extrusion molding, continuous composite tape winding, outer pipe extrusion cladding, and cutting/warehousing — enabling seamless continuous on-line production.
At the heart of the production line is an advanced tape winding system featuring precision tension-controlled winding with closed-loop monitoring. The system achieves winding accuracy up to ±0.2 mm, with winding tension ranging from 1 to 100 kg and adjustable winding angles from 0 to 90 degrees. This level of precision ensures uniform reinforcement layer thickness and optimal fiber orientation, directly translating to superior pressure ratings and pipeline integrity.
The production line supports a diverse range of reinforcement tapes, each serving distinct pressure and cost optimization goals:
Glass Fiber Reinforced Tape (GFRTP): Industry standard for general-purpose, cost-effective reinforcement at moderate pressure levels
Aramid Tape (Kevlar® equivalent): Exceptional strength-to-weight ratio for demanding high-pressure applications
Polyester Tape: High corrosion resistance, ideal for chemically aggressive environments
Steel Cord: Maximum pressure rating for the most demanding high-pressure oil and gas applications
The production line adopts a constant tension automatic control system for tape winding. The human-machine interface allows precise winding angle and tension adjustments across multiple tape layers, ensuring consistent reinforcement quality and eliminating tension loss that could compromise pressure ratings.
Computerized centralized control enables precise inner pipe weight control, synchronized traction, fully automatic pipe coiling, and multi-station automated layer control. This reduces manual intervention, improves product consistency, and ensures every meter of pipe meets rigorous international safety and durability standards.
The production line produces flexible RTP pipes that can be supplied in coils, enabling long-distance seamless installation with minimal joints — a significant advantage over traditional rigid steel pipes. A single RTP line can accommodate up to 16 tape winding heads for multi-layer reinforcement, giving manufacturers complete flexibility to scale reinforcement intensity according to specific pressure requirements.
Performance Metric | RTP (4-10 inch Line Output) | Traditional Steel Pipe | Advantage |
|---|---|---|---|
Pressure Resistance | Up to 32 MPa working pressure; burst pressure >100 MPa possible | Up to ~20 MPa for carbon steel | RTP meets or exceeds standard steel ratings |
Weight | ~20% weight of metal pipes | Heavy — requires heavy lifting equipment | Massive logistical advantage |
Corrosion Resistance | Excellent — resists H₂S, CO₂, brine, acids | Poor — requires inhibitors, cathodic protection, coatings | Extended service life, lower maintenance |
Installation Speed | Can be laid at >10 km/day | 70+ days for equivalent line | 35x faster installation |
Installation Cost | 20% lower than steel pipe | Baseline | Significant capital savings |
Service Life | Up to 50+ years | 15–25 years before corrosion replacement | 2–3x longer operational life |
Lifecycle Cost | 1/3 of carbon steel pipe | Baseline | Massive TCO advantage |
