Thermoplastic Composite Pipe (TCP) is a developing of the fiber reinforced thermoplastic pipe (RTP) technology. In this conception, the solid wall pipe consists of an inner liner, thermoplastic composite reinforcement layers and a protective outer coating. 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 pipeline is free of corrosion due to its none metallic fiber reinforcement (e.g. glass, aramid, carbon), and it shows other advantages of superior structural integrity, safe and reliable, durable in case of cyclic loads.
Compared with steel pipe, the total cost (pipe cost plus Installation) can range from 5 to 30% cheaper than steel line pipe. Although the unit cost of RTP/TCP is higher than steel, but the installation costs (workforce plus time) are considerably lower, because no pipe benders or welding crews are needed, and less handling equipment and traffic is required. The most valuable thing for customer is that the quick installation can save log of time for project, in many cases, 3000 feet of line can be put into place in 1 to 2 hours.

The most valuable thing for customers is that the quick installation can save a lot of time for the project. In many cases, 1km of pipeline can be put in place in a day.
Reinforced thermoplastic pipe (RTP) has the highest strength to weight ratio and the longest continuous length of any commercial hose, using fewer pipe connections, so the product is cost-effective and easy to install.
The pipe can be used in a diverse range of applications: onshore and offshore; oil, gas, refined fluids, and brine; new installation or pull-through rehabilitation in aging existing steel pipeline systems. In many cases, no trenching is needed, minimizing cost and mitigating operational disruption.
