Brittle temperature-plastic good on HDPE double wall corrugated pipe double-walled metal bellows 400 low temperature impact resistance HDPE double wall corrugated pipe is -70 ℃. In general, low temperature (above -30 ℃) does not have to take special protective measures during construction, winter construction convenient mpp double-wall bellows, and, HDPE double wall corrugated pipe has a good impact resistance. Because HDPE molecule chemical stability, good no polarity, excellent chemical stability. Apart from a few strong oxidant, most of them can not afford to undermine the role of chemical mediators. Usually the soil environment, the power, pH factor will not damage the pipe wall corrugated pipe dn1000, no bacteria, no scaling, its circulation area will not increase over time and reduce run. HDPE double wall corrugated pipe through the gold plastic advantages: 1, the unique structure, high resistance to external pressure, impact resistance, has a ring of flexible, smooth wall friction is small, the same diameter pipe can be larger traffic through; socket interface flexible connection, connecting convenient, high reliability, easy to leak. 2, light weight, quick construction, reduce costs. 3, the buried life of five years or more. 4, double-wall corrugated polyethylene pipe belonging hydrocarbon polymers, molecular polarity, acid corrosion. 5, the raw material for green materials, non-toxic, non-corrosive, non-scaling, recyclable. 6, wide temperature range, -60 ℃ environment does not break in the pipeline, the maximum temperature of the transmission medium 60 ℃. 7, comprehensive project cost and concrete roughly equal, low operating costs. 8, no basis under good soil conditions. 800mm wall bellows _ Xiongxian-plastic made on gold-plastic Products Co., Ltd. to provide a double-wall corrugated pipe _ gold. Pass on the Xiong Jin Plastic Products Co., Ltd. (www.jinshangtongsj.com) strong, credible, in Baoding composite pipe industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the gold-plastic and you hand in hand into the brilliant, for a better future!
