Product Description

HDPE Pipe Induction 
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.


The comprehensive performance of PE pipes can be used in the fields of application|Temperature resistance|Low temperature embrittlement temperature is very low, and it can be used in the range of -40ºC to 60ºC, and there will be no pipeline embrittlement during installation and construction in winter.

Our Advantages

 

  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
