mpp single wall corrugated pipe for the power control cables, communication cable, buried cable protection. HFFB power tubes (MPP single wall corrugated pipe) is a polypropylene (MPP) as the main raw material, the use of composite materials to enhance the new structure wall pipe modified special formulation and processing technology made of a new structure, high strength, good heat resistance Construction is simple and cost savings and other advantages. As the excavation of the new power tubes with industry, HFFB power tubes (MPP single wall corrugated pipe) to solve the difficult process of forming and composite materials modified by industry difficulties, creatively designed a novel product structure and button-type connection, therefore , the technology has broad application prospects. MPP enhanced ripple (HFB) casing product superiority ◎ reliable quality, cost, light weight, high steel ring, construction convenient; under conditions such as load, MPP single wall corrugated pipe requires only a thin wall to meet requirements, with the same specifications required by MPP ring stiffness solid wall pipe 40-70% savings compared to the cost of materials. ◎ embedded rubber ring bayonet coupling, anti-shedding and good sealing performance, if necessary, welding, engineering basically no maintenance costs. ◎ heat, wear, electrical insulation, while at higher temperatures can still maintain a good anti-external pressure capability, suitable for use as high voltage power lines sheath tube. ◎ curved inner wall corrugated structure, and cable "point contact", wearing a good cable performance. ◎ pull-resistant pressure, firmness and flexibility: a stronger stretch resistant flexible external pressure and better performance.
