HDPE Dredging pipeline

Short Introduction:
HDPE pipes are following ISO 4427 / AS / NZS 4130 / BS EN 12201 / SABS standards with black / blue colors, which get CE certificates and ISO 9001 quality management system certificates. Connected fittings are available. For more details about JUNNUO HDPE fresh water supply pipes, please contact us!

Dredging pipeline is mainly used to remove materials (sludge, mud, sand and sediments, etc.) from the depths of oceans, lakes, rivers and ponds, and Pratt & Whitney HDPE dredging pipes from famous raw material suppliers such as Borealis, Shanghai Petrochemical, PE100 raw materials supplied by top companies such as Sinopec are made at a low price and high quality.

PUHUI HDPE dredge pipe are usually produced in 6m or 12m lenghts. The pipe can be provided from DN160-1600mm with various wall thickness as per different SDR & designed pressure rating, and custom-made steel backing rings are available.

HDPE pipe is an ideal solution for dredging pipeline. PUHUI HDPE pipe has the following advantages:

  • Corrosion resistance: HDPE is an inert material that is resistant to various chemical media.
  • No leakage: HDPE pipe is connected by hot melt, and its interface strength is higher than that of the pipe itself.
  • Light weight: Light weight Easy to assemble or disassemble.
  • High toughness: The elongation at break of HDPE pipes is generally above 500%. For the uneven settlement of the foundation, it has strong adaptability and good seismic performance.
  • Rapid crack propagation: Excellent resistance to rapid crack propagation (RCP).
  • Excellent flexibility: Excellent flexibility and scratch resistance.
  • Good wear resistance: low wall friction coefficient, low flow resistance and strong conveying capacity.
  • Non-excavation installation: A variety of non-excavation methods are available for easy construction and installation.
  • Low engineering cost: low system cost, low maintenance cost and long service life.
  • Green, Recyclable, environmentally friendly: HDPE materials can be repeated.
