Xuzhou, Suqian HDPE double wall corrugated pipe Name: HDPE double wall corrugated pipe specifications: DN110 --- DN800 Features: 1, compression capability. Wall ladder structure greatly increases the pipe ring stiffness. 2, engineering and lower total cost. Compared with the same pipe material can save half of the raw material, slotted earthwork also greatly reduced. 3, to facilitate construction. Because the pipe lighter, easy handling and connection, when there is no need to use smaller diameter crane. 4, flow, easy to maintain. Pipe wall is smooth, so compared to the same specifications of pipe flow, while the pipe clogging, easy to maintain. 5, good low temperature resistance, impact resistance. Polyethylene pipe material embrittlement degree is -70 ℃, generally low, especially in northern areas affected construction. 6, stable performance, acid and alkali. Because there is no polar molecules HDPE, pipe stability excellent general fluid will not cause damage to the pipe. 7, long service life.
