HFB single wall power bellows

Heat-resistant insulation, safe and reliable: The main material of the pipeline is modified polypropylene, which has good insulation properties and can still maintain good resistance to external pressure at higher temperatures. It is suitable as a protective sleeve for high-voltage power lines .

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

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