HDPE dredging pipe introduction
The inner wall of the PE water supply pipe is smooth and does not change with the time of use. The friction resistance is small, which saves energy. The pressure loss is about 30% smaller than that of the steel pipe. A smaller diameter than the steel pipe can be selected. Good hygienic performance, no additives, no possibility of polluting drinking water, ISO standard graded polyethylene material is 0 (lower grade), mold-free material, compared with other commonly used plastic materials, polyethylene's mold resistance It is much higher and does not accumulate scale after long-term use.
PE pipe is suitable for general purpose pressure water delivery and drinking water transportation with temperature not exceeding 40ºC and nominal pressure below 1.6MPa. Mainly include municipal buried water supply, construction (drain) water, farmland irrigation, water feature engineering, fine sand/slurry dredging etc.
The flanged HDPE dredging pipe is easy to be connected, which reduced the swings caused by the waves and makes the medium smoother in the pipe.
The HDPE dredging pipes are used for drainage, water-logging, dredging and sand discharging of port.
