Nano-modified polypropylene (HPPM)

Nano-modified polypropylene (HPPM) square electric power double-wall corrugated pipe is a new type of structural wall pipe material made of heat-resistant, heat-oxygen aging-resistant and nano-flame-retardant modified polypropylene as the main raw material, and adopts the high-strength waveform design and processing technology. It has a series of advantages, such as novel structure, high compressive strength, fast and convenient construction, high temperature resistance, flame retardant, anti-vibration and long service life.

Product performance

1. Good flexibility: excellent flexibility to adapt to ground settlement or changes in the construction of the foundation to ensure that the tube on the cable protection.

2. Saving material: in the pipe to achieve the same performance under the premise, you can put less material.

3. High heat resistance: the main material is not composite polypropylene septum, Vicat softening temperature of 135 ℃ or more, high temperature still maintains the ability to resist external pressure.

4. Energy-saving and environmentally friendly: the main material consists of carbon and hydrogen two elements, pipe waste can be recycled for the second time, there is no white pollution in the production and recycling process.

5. Safe to use: non-conductive, non-heat transfer, with good adiabatic properties, in line with the requirements of high-voltage power safety requirements.

6. Corrosion resistance: acid, alkali, salt and other chemical media and no electrochemical erosion, service life of more than 50 years.

7. Smooth wall: smooth surface inside the tube, low friction coefficient, in contact with the cable, drag resistance is small.

8. Low-temperature resistance: the working temperature range span is large, can adapt to a variety of climatic conditions under construction.

9. High degree of sealing: can be connected by special card tracing, no welding seams and flying edges, will not rub the cable.

10. Good ring stiffness: special single-wall corrugated structure design and high modulus of elasticity of the material, so that it has a high ring stiffness, high compressive strength.

Applications

Nano-modified polypropylene (HPPM) square power double-wall corrugated pipe is mainly used in 10KV or more high-voltage transmission lines and cables with urban and rural open excavation cable drainage project.

Product links

Nano-modified polypropylene (HPPM) square electric power double-wall corrugated pipe is connected by special clamp. The use of special clamp connection, must keep the pipe and take over the mouth in the same straight line, the mouth of the first set of elastic sealing ring, and then the clamp on the end of the two tubes can be fastened. Pipe laying in the ditch should be manually speed transfer, it is strictly prohibited to roll down the ditch.
