the hollow ring structure between the inner and outer walls of the high-strength PVC HPVC double-wall corrugated pipe, which makes full use of the principle of I-beam structure to improve the cross-sectional inertia distance and high ring stiffness. This type of corrugated pipe has the characteristics of light texture, good toughness and high strength. The product can replace the current PVC-C power pipe, PVC-U communication pipe, MPP single-wall corrugated pipe and other power cable protection casings.

Although the traditional PVC-U pipe has high strength, when the ambient temperature is as low as 0 ° C, the shortcomings of insufficient pipe toughness and poor impact resistance are exposed. What's more, the climate difference between the north and the south of our country is large, and the PVC pipeline has to stop construction in the northern region in winter; in some earthquake-prone areas, the traditional PVC-U pipeline has poor impact resistance and is very easy to break in the earthquake; in addition, some construction units do not consider environmental factors in the process of laying pipelines, resulting in frequent systemic accidents of PVC-U pipes. High-strength PVC HPVC double-wall corrugated pipe is combined with international pipeline experience and the actual situation of our country. According to the shortcomings of poor low temperature toughness and poor heat resistance of traditional PVC pipes, the raw material formula is improved, and high-strength PVC (HPVC) pipe is developed. It not only maintains the high strength of traditional PVC-U, but also improves the toughness and heat resistance of the pipe, and increases the safety and environmental applicability of the pipeline.

High-strength PVC HPVC double-wall corrugated pipe has the characteristics of high strength, high toughness, corrosion resistance, high compression resistance and good flame retardancy. Specifications range from 100, 150, 175, 200, 225; the product is widely used in cable protection sleeves for crossing roads and bridges.
