Product Description
Reinforced Thermoplastic Pipe is one kind of high-pressured plastic compound tube, consisted of three layers, the outer layer and liner are a PE80 or 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 (under ground), the intermediate layer is the enhanced tape, the reinforced material may be the polyester fiber or the aramid fiber and so on. The pipes use many kinds of connection forms such as enhancement inline coupling, swaging fitting, flanged joint to connect. The RTP pipe general application temperature for -42ºC~135ºC, the max operation pressure may reach 32MPa most greatly.
Advantages of RTP pipe
1. Anticorrosion
The walls both inside and outside of the RTP pipe have the good anticorrosive property, thus made it suitable in many kinds of corrosive medium and each kind of corrosive environment. (Reference standard:TR-19 thermalplastic piping for transport of chemicals)
2. High pressure resistance
The RTP pipe has the high loading capacity. By choosing different enhancement material, the maximum service pressure may achieve 32MPa, and the bursting pressure may even reach as high as above 100MPa.
3. Heat resistance & thermal insulation
The RTP pipe's application temperature scope is - 42ºC~135ºC, may satisfy the temperature demands of the majority situations, and the thermal conductivity is only 0.48w/m*k, which is the 1/100 of steel pipe.
4. High transportability
The inner wall of RTP pipe is very smooth, hard for scaling and wax precipitation, the flow resistance is low, high wear-resistance, delivery capacity lasting invariable, so the transported pipeline's maintenance cost is reduced.
(1)The material of RTP pipe's inner pipe is polyolefin, so the roughness equivalent of inner wall may reach 0.05mm, but under ordinary circumstances steel pipe roughness equivalent achieves 0.19mm, the used steel pipe even reaches 0.60mm.
(2)RTP delivery capacity surpasses the conventional pipeline 50%.
5. Abrasion performance
RTP outer and inner pipe's material and steel 70° tilt angle of wear test (mud jet velocity 14m/s)

6. High flexibility
RTP pipe toughness is extremely high, has the good impact resistance, and good ability of anti-ground vehicle load ability, anti-soil deposition, anti-earthquake and so on. Since the RTP pipe has good flexibility, usually carries on the nature compensation through the serpentine layout while installing, with no need of the thermal compensation installation, and thus saves the installation cost.
7. Easy Construction
(1) The RTP pipe may look like the electric cable in coil to set the construction, every day may lay down at least 3 kilometers;
(2) The RTP pipe tensile strength is high, when pipe is lay down, the long time maximum puling force may amount to 5 tons, and the instantaneous maximum puling force may amount to 10 tons.
8. Small quantity of joints
The single length of RTP without fitting may amounts to 150-400 meters, therefore joints are very few to the pipeline, and the reliability is higher, the cost is saved.
9. High cost performance
Demonstrated according to the German Weicon Company that compares with the carbon steel pipeline, the RTP pipe may save over 25% of investment totally.
10. Safety and health
The RTP pipes, non-toxicity, does not decompose, is the environment friendly green material. It conforms to the GB/T 17219-1998 transmission and distribution equipment of domestic potable water and the shielding material security evaluation criteria.
11. long service
The RTP's working life can be designed according to customer requirements, and the max working pressure can reach 50 years.
