HDPE Dredging pipeline

HDPE Dredging pipeline is a pipe made of high-density polyethylene (HDPE) material, which is specially used for dredging operations such as offshore sand and mud pumping. This kind of pipe has many advantages, including light weight, easy installation and disassembly, good flexibility, strong corrosion resistance, UV resistance, long service life, etc.

Function

The main function of HDPE Dredging pipeline is to clean and maintain the waterways of waterways, ports, rivers, lakes and other waters to ensure the safe passage of ships. ‌

HDPE Dredging pipeline can restore the depth and width of waterways and improve the navigability of waterways by extracting silt, sand and mud to the shore or specific locations. This kind of pipeline is usually powered by a large pumping station, and the bottom mud and water mixture is pumped into the pipeline by a pump, and then transported to the target location through the pipeline. Dredging pipelines have a wide range of applications, including but not limited to port engineering, waterway engineering, water conservancy engineering and other fields. By effectively cleaning silt, sand and mud and other materials, HDPE Dredging pipeline maintains the smooth flow of waterways, improves the navigability of waters, and ensures the smooth progress of shipping and water conservancy projects.

Advantages and characteristics

1. Light weight: The weight of HDPE Dredging pipeline is only one-eighth of that of steel pipe, which greatly reduces the difficulty of installation and transportation.

2. Easy installation and disassembly: Through the movable flange connection, installation, disassembly and transportation become simple and quick, thereby shortening the start-up time and improving work efficiency.

3. Good flexibility: It has good flexibility, can be bent, is easy to connect, and adapts to various complex construction environments.

4. Strong corrosion resistance: It can remain unchanged for 50 years in harsh environments such as seawater, and has extremely strong corrosion resistance.

5. Anti-ultraviolet: Adding a certain proportion of carbon black can enhance the anti-ultraviolet ability and prevent pipeline aging and embrittlement.

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.
