16Inch HDPE pipe Applied for Float Dredge Pipe for sand slurry dredging
The inner wall of the HDPE 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.
HDPE pipe is suitable for general purpose pressure water delivery and drinking water transportation with temperature not exceeding 40℃ 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.
Benefits of HDPE pipe for sand/slurry dredging:
a. High Corrosion Resistance
HDPE material structure is saturated molecular group, with great chemical stability,good resistance of various corrosion mediums(acid,alkali,salt)and organic solvents.
b. High Impact Resistance
c. High Pressure Resistance
d. Environment Proctection
The manufacturing and processing of wear resistant HDPE pipe is low carbon,without wasted water,exhausted gas and waste residue,which saves 20% energy compare with the traditional steel pipes.
e. High Flexibility
f. Non-scaling
g. Low energy consumption
