HFB Single - Wall Power Bellows

Heat-resistant insulation, safe and secure : The main material of the pipe is modified polypropylene, which has good insulation properties. At the same time, it can still maintain good resistance to external pressure at higher temperatures. It is suitable for use as a sheath pipe for high-voltage power lines.

Heat-resistant and insulated, safe and reliable: The main material of the pipe is modified polypropylene, which has good insulation properties and can still maintain excellent resistance to external pressure at rather high temperatures. It is suitable to be used as casing pipes for high-voltage power lines.

Tensile and pressure resistant, both rigid and flexible : It has stronger tensile and external pressure resistance and good flexibility. The connection adopts clamp sealing connection, which is convenient and reliable. Low temperature resistant, suitable for winter construction : As a modified polypropylene , it has good low temperature impact resistance. In southern China, it can be used for construction most of the year .

Tensile and pressure resistant, rigid and flexible: It has stronger tensile resistance, external pressure resistance and better flexibility. The joints are sealed with a clamp, which is convenient and reliable. Low temperature resistant, suitable for constructions in winter . As modified polypropylene, it has good low - temperature impact resistance. In southern China, constructions can be carried out most of the time.

Reliable quality and cost savings : Lightweight, with a density of only 0.9-0.92g /cm³, it is the lightest material currently available for buried pipes, significantly reducing transportation and installation costs . Furthermore , under constant load conditions, HFB power corrugated pipe requires only a thinner wall, saving 40-70 % in material costs compared to solid-wall pipes with the same ring stiffness requirements . Compared to PVC double - wall corrugated pipe and fiberglass reinforced plastic sand-filled pipe, its overall cost is roughly the same, yet it offers superior performance. Connections are made using pipe buckles or hot-melt welding, eliminating maintenance costs.

Reliable quality and cost saving: light weight with a density of only 0.9-0.92g / cm3, it is the lightest material among all buried pipes at present, which can greatly reduce transportation costs and lifting costs during installation; meanwhile, under equal load condition, HFB power bellows can meet the requirements with a thinner wall. Compared with the solid-wall pipes of the same ring stiffness, it can save 40-70% material costs. The comprehensive cost is basically the same with that of PVC double-wall bellows and glass reinforced plastic sand pipe, but its performance is superior. The construction connection adopts pipe buckle socket or hot-melt welding, which basically has no engineering maintenance costs.
