Reinforced thermoplastic pipe (RTP) can achieve high pressure and large diameter Reinforced thermoplastic pipe (RTP) has the advantages of high pressure resistance, flexibility, corrosion resistance, impact resistance and wear resistance, as well as the characteristics of light weight, spool-able and quick laying with less joints, therefore it is very suit for the application of oil & gas onshore pipeline.

TCP is an advanced iteration of fiber reinforced RTP pipe, defined by its fully bonded, monolithic structure. It retains the three-layer framework but with critical material and structural upgradesall layers—liner, reinforcement, and sheath—are melt-fused at the molecular level during manufacturing, eliminating discrete interfaces and forming a single integrated structure.

• Inner Liner: Same as RTP (thermoplastic for containment), but engineered for compatibility with high-temperature fusion processes.
• Reinforcement Layer: Fibers (glass, carbon, or aramid) are 100% impregnated with thermoplastic resin (e.g., modified PE) to eliminate voids. This forms a continuous, dense composite matrix.
• Outer Sheat: A thermoplastic layer fused to the reinforcement via thermal processing, creating a seamless transition between layers.

The reinforced glass fiber is completely impregnated with thermoplastic resin, and forms a fully bonded reinforcement layer. All layers, including the outer coating, are melt-fused together ensuring a bond between the layers that is as strong and durable as the base materials.

TCP represents a technological advancement over RTP, addressing RTP’s key limitations—particularly delamination risks and structural vulnerability—through its fully bonded, void-free design. While RTP remains suitable for low-to-medium pressure, non-critical applications, TCP is engineered for high-pressure, harsh-environment scenarios (e.g., deep oil & gas, chemical transport) where reliability and durability are paramount.
