Compound enhanced CM double wall corrugated tube

Product overview: Composite reinforced HFCM double wall corrugated pipe, the outer wall of a hollow annular structure, make full use of the I-beam structure principle and improve the rectangle of inertia, high ring stiffness. Products with high strength, toughness, texture and light, etc.The product can replace the MPP excavation, single arm bellows, PVC-C power tube, PVC-U communication pipes. Product features: 1 high strength and toughness; 2 corrosion resistance, anti - termites and weathering resistance; 3 anti UV, anti-aging, good weather, long service life; 4 good flame retardant, the fire is extinguished; 5 high insulation, leakage prevention; 6 can melt welding.
