HFB single-wall corrugated electrical conduit

Heat-resistant insulation, safe and reliable: The main material of the pipe is modified polypropylene, which has good insulation performance and can maintain good external pressure resistance even at high temperatures, making it suitable for use as a sheath pipe for high-voltage power lines. Tensile and pressure resistant, combining rigidity and flexibility: It has stronger tensile and external pressure resistance and good flexibility. The connection uses a clamp seal connection, which is convenient and reliable. Low temperature resistance, suitable for winter construction: As modified polypropylene, it has good low-temperature impact resistance. In most parts of southern China, construction can be carried out for most of the year. Reliable quality, cost savings: Light weight, density is only 0.9-0.92g/cm3, which is the lightest material among all buried pipe materials, greatly reducing transportation costs and installation hoisting costs; at the same time, under the same load conditions, HFB corrugated pipes only need a thinner pipe wall to meet the requirements, saving 40-70% of material costs compared with solid wall pipes with the same ring stiffness requirements; the comprehensive cost is basically the same as that of PVC double-wall corrugated pipes and fiberglass reinforced pipes, but the performance is superior. The construction connection adopts pipe coupling or hot melt welding, and there is basically no engineering maintenance cost.
