RTP Reinforced Thermal Plastic
Reinforced Thermoplastic Pipe is one kind of high-pressure plastic compound tube with the outer layer and liner are a PE80 or a PE100, the outer layer according to needs to be possible to choose the white color (on the ground against ultraviolet ray) or the black color (underground), the intermediate layer is the enhanced tape, the reinforced material may be the polyester fiber or the aramid fiber or so on. The pipes use many kinds of connection forms such as enhancement in-line coupling, swaging fitting, flanged join to connect, the RTP pipe general application temperature, or -42°C ~ 135°C. The max operation pressure may reach 32MPa most greatly
Reinforced thermoplastic pipe (RTP) is an alternative to traditional pipe lining materials. It consists of three basic layers including a thermoplastic liner, helically wrapped continuous high-strength fiber reinforcement, and an external thermoplastic jacket. The liner acts as a bladder, the fiber reinforcements provide strength, and the jacket protects the load-bearing fibers. Applications include oil and gas gathering and produced water transfer.
The main products are all kinds of composited pipe including Reinforced Thermoplastic Pipe. The RTP product’s research and development began in 2003 and was listed as the national project.
The company covers an area of approximately 16000 square meters, the fixed asset is about 7 millions us dollars, has staff of more than 70, including more than 20 engineers and technicians and 4 senior engineers.

Advantages of RTP
Anticorrsion
The walls both inside and outside of the RTP pipe have a good anticorossive property, , this made it suitable in many kinds of corrosive medium and each kind of corrosive environment. (Reference Standards: TR-19 thermoplastic piping for transport of chemicals)
High-Pressure Resistance
RTP has high pressure capacity. By choosing different enhancement materials, the maximum service pressure may achieve 32 MPa, and the bursting pressure even as high as above 100MPa.
Heat Resistance and Thermal Insulation
The RTP’s Application temperature range is -42°C ~ 85. It can satisfy the temperature demands of the majority of situations. And its thermal conductivity is only 0.48w/m*k, which is 1/100 of steel pipe.
High Transport Capacity
The inner wall of RTP is very smooth which is hard for scaling and wax precipitation. The low flow resistance and permanent delivery capacity reduce the pipeline’s maintenance cost.
Abrasion Performance
Through a 70° inclined angle wear test (mud injection speed 14m/s), RTP’s wear resistance is 5 times that of steel.
High Flexibility
RTP’s toughness extremely high which has good impact resistance, the ability of anti-ground vehicle load ability, anti-soil deposition, anti-earthquake, and so on. Because of RTP’s good flexibility. RTP usually carries on the nature compensation through the serpentine layout while installing, without thermal compensation installation, and thus saving the installation cost.
Easy Construction
The RTP can construct in coil like electric cable, which can be laid at least 3 km a day. When the pipe is laying, the long time maximum pulling force can reach 5 tons. And the instantaneous maximum pulling force can reach 10 tons.
Fewer Joints
The length of a single RTP amounts to 150-180 Meters. Therefore joints are fewer, which improves reliability and saves cost.
High-cost performance
According to the German Wiecon Company demonstrated that compared with the carbon steel pipelines, the RTP could save over 25% of the investment.
Safety and Health
The RTP is non-toxicity and not decomposing, which is an environment-friendly green material. It conforms to the GB/T 17219-1998 which is a safety assessment criteria for drinking water’s transportation and distribution equipment and protective materials.
Long Service Life
RTP’s working life can be designed according to customer requirements. The maximum working life can reach 50 years.
