(8) PVC honeycomb pipe

PVC honeycomb pipe is a honeycomb plastic pipe composed of several hexagonal children. The cross-section shape is like a honeycomb, and it adopts a reasonable mechanical structure of one-body porous honeycomb, so that the pipe is 10-100 times higher than ordinary plastic pipes. The most commonly used is the seven-hole honeycomb pipe. The inner diameter of the hole is 33mm, the length is 6000mm, and the allowable deviation is 0-30mm. It has the characteristics of acid resistance, aging resistance, flame retardancy and insulation properties. Its use temperature is -20 degrees to 40 degrees, and it can be used in cold and summer areas. The service life is as high as 50 years.

Product features:
● 1. Strong corrosion resistance, good electrical insulation
● 2. Clear porous separation, easy and convenient threading.
● 3. The holes are closely arranged to improve the utilization rate of communication holes.
● 4. One tube is porous, the construction is convenient and fast, and the project cost is low.
● 5. Product integration structure, high strength and long service life.

(10) MPP modified polypropylene (trenchless power pipe)

MPP trenchless power pipe is also known as MPP jacking pipe or torah pipe. MPP power pipe uses modified polypropylene as the main raw material, so it does not need to be dredged, excavated and damaged on the road. Construction projects such as pipelines and cables are laid in special areas such as roads, railways, buildings, and riverbeds. Compared with the traditional "trenching and buried pipe method", the trenchless power pipe project is more suitable for the current environmental protection requirements, and removes the disturbing factors such as dust king flying and traffic congestion caused by traditional construction. This technology can also lay pipelines in some areas where excavation operations cannot be carried out, such as historical site protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc. Divided into ordinary and enhanced types. The ordinary type is suitable for excavation and laying construction and trenchless crossing construction projects with a buried depth of less than 4M, and the enhanced type is suitable for projects with a buried depth of more than 4M in trenchless crossing construction.

MPP power pipe advantages:
1, Hubei MPP power pipe has excellent electrical insulation.
2, Wuhan MPP power pipe has high thermal deformation temperature and low temperature impact performance.
3, Ezhou MPP power pipe tensile and compressive performance is higher than HDPE.
4, Huanggang MPP power pipe light, smooth, friction force is small, hot melt welding butt.
5, Xianning MPP power pipe long-term use temperature - -5~ 70C.
