Reinforced Thermoplastic Pipe Extrusion Line | Patented One-Step Winding Technology | Turnkey Solution
JMG Machinery's Metal Rope Winding RTP Pipe Production Equipment is a complete turnkey system engineered for manufacturing high-performance Reinforced Thermoplastic Pipe (RTP) with metal rope, steel wire, or wire mesh skeleton reinforcement. At the core of this system lies our patented metal rope winding technology (Patent No. ZL201721360511.X), which enables a one-step integrated production process with precise tension control, eliminating the inefficiencies of traditional two-step processes that require repeated uncoiling and reel transportation.
The production line is designed for continuous 24/7 operation and delivers pipe diameters ranging from DN50 to DN300 mm (2″ to 12″), with reinforcement layers adjustable from 1 to 6 layers to accommodate different pressure ratings.
Patented One-Step Integrated Process — Our proprietary winding technology eliminates the need for repeated uncoiling and reel transportation of the inner pipe, significantly improving both production efficiency and product consistency compared to conventional two-step processes.
Precision Tension Control — Multi-axis independent tension-controlled pay-offs ensure uniform reinforcement layers, eliminating overlaps or gaps. The constant tension automatic control system is essential for achieving one-step multi-layer reinforcement winding.
Wide Material Compatibility — The winding unit supports steel wire, aramid belts, glass fiber rovings, and metal ropes, providing flexible reinforcement solutions for different pressure ratings and application scenarios.
Intelligent Monitoring — Real-time tension monitoring prevents wire breakage or waviness, ensuring consistent product quality throughout the production run.
Energy Efficiency — Heat-profile regulation reduces energy consumption by up to 15% compared to conventional equipment.
Rapid Changeover — Quick-change die heads reduce specification changeover downtime to just 20–30 minutes, significantly enhancing production line flexibility.
High-Speed Production — Maximum winding speed of 40 m/min with extrusion output of 350–600 kg/h, delivering excellent production throughput.

A complete metal rope winding RTP production line consists of the following core units:
Inner Pipe Extrusion Unit — Extrudes the thermoplastic liner
Reinforcement Winding Unit — Spirally winds metal ropes, steel wires, or reinforcement tapes around the inner liner
Outer Sheath Extrusion Unit — Extrudes the outer protective layer
Cooling and Sizing System — Ensures dimensional stability
Haul-off, Cutting, and Coiling System — Enables cut-to-length and coil packaging
RTP pipes produced on this line are widely deployed in demanding environments:
Oil & Gas — Gathering and transmission pipelines, single-well gathering lines
Geothermal Energy — Deep geothermal development, hot spring water transmission
Municipal Infrastructure — Central heating secondary pipe networks, municipal water supply
Mining — High-pressure water transmission, slurry transport
High-Pressure Fluid Transport — Corrosive media and chemical transportation
Emerging Applications — Hydrogen transmission, offshore risers
