Product Name: PE Double Wall Corrugated Pipe for Buried Ground Execution Standard: GB/T19472.1-2004 Pipe Caliber: DN200, DN300, DN400, DN500, DN600, DN700, DM, HDPE Double Wall Corrugated Pipe Product Series Features of DPE Large Diameter Double Wall Corrugated Pipe: HDPE Large Diameter Double Wall Corrugated Pipe was developed in the early 1990s DN800 It is a new type of sewage discharge engineering pipe. It has a perfect design concept and a unique hollow structure, so that the stress on the pipe wall is very uniform. PE double wall corrugated pipe mainly has the following 13 advantages: 1, low engineering cost 2, good pipe ring stiffness: there are 2 levels of ring stiffness of the pipe: S1, S2S1-24kN/M2S2-28kNM2 can be selected according to the different requirements of households to use poor grade 3, excellent shock resistance 4, chemical corrosion resistance 5, high density, light weight 6, excellent Good hygienic properties7. Good Dynamic fracture toughness KD value 8, excellent low temperature resistance 9, good electrical insulation performance 10, smooth inner wall, low water resistance, no fouling 11, good sealing performance - no leakage 12, excellent impact resistance 13, long service life
