Reinforced Thermoplastic Pipe (RTP) is replacing steel and pure plastic pipes. JMG Machinery's non-metallic rope winding line produces composite pipes (ID 50–150 mm) at 10 m/min using polyester or aramid reinforcement. This article covers equipment composition, working principle, key parameters, and advantages in oil/gas, water supply, and municipal applications.
The glass fiber tape winding reinforced composite pipe (RTP) production equipment is a high-precision continuous manufacturing line featuring multi-axis CNC control and constant tension winding technology. Pre-impregnated glass fiber tape is spirally wound around a thermoplastic inner pipe surface at controlled angles and tensions to form a multi‑layer cross‑wound network reinforcement structure, followed by an outer protective layer extrusion. The complete line consists of an inner pipe extruder, vacuum sizing tank, multi‑stage winding units (with infrared or hot air heating), outer pipe extruder and cladding die, cooling and haul‑off systems, and a fixed‑length cutting device. It accommodates pipe diameters from 50 to 600 mm and pressure ratings up to 30 MPa. This equipment is widely used in oil & gas transmission, municipal water supply, chemical corrosion protection, industrial slurry transport, and new energy pipelines, representing an advanced alternative to traditional metal and
Composite pipes, particularly Reinforced Thermoplastic Pipes (RTP), offer outstanding corrosion resistance, light weight, and long service life. However, connection technology has long been a bottleneck limiting their large-scale application. This article systematically reviews the technological evolution of composite pipe joint equipment, highlighting fully automatic continuous feeding systems, precision temperature-controlled heating, enhanced stability and reliability, and a threefold efficiency gain compared to conventional methods. The paper also analyzes the global composite pipe market growth (CAGR exceeding 5%), explores application prospects in oil & gas, geothermal, and district heating, and outlines key international and regional standards (ASME, GOST, Chinese national standards). Fully automatic composite pipe joint equipment is emerging as a critical enabler for upgrading the composite pipe industry.
