HDPE dredging pipe

hdpe dredging pipe

High-density polyethylene dredging pipe is formed by continuous extrusion of polyethylene using a special extruder and a specially designed mold.

Raw material : PE100 grade pure high-density polyethylene ( HDPE ) raw material   PE100
color : pipe body black specifications : outer diameter 25mm-1200mm   

High-density polyethylene dredging pipes have superior comprehensive performance, high wear resistance, light weight, easy transportation and installation, no need for large-scale mechanical construction, and each section can be made arbitrarily according to user needs. It has excellent wave impact resistance, ring stiffness, and high tensile strength. It can withstand the impact of wind and waves on the sea surface, has a low water resistance coefficient, low wear resistance, high efficiency in conveying sediment, good corrosion resistance, and extremely high chemical stability. It can resist corrosion from various corrosive media (acids, alkalis, salts and seawater) and organic solvents within a certain temperature and concentration range. The pipeline products are environmentally friendly and odorless, will not be corroded by microorganisms such as shellfish and fungi in the ocean or sewage, will not produce scale, and have excellent low temperature resistance.

The main uses of HDPE dredging pipes : land reclamation, port construction, sand pumping projects, filling projects and other related mud and slurry transportation, riverside sand plants, lakeside sand plants, mortar transportation, cutter dredgers , sand pumping ships and other types of sand ship pipes, pump pipes, sand and gravel transportation pipes.

High-density polyethylene dredging pipes are widely used in the dredging industry at home and abroad, special pipes for dredgers, sand pumping pipes, etc.

Features of HDPE dredging pipe products:
1. Light weight, only one-eighth of steel pipes.
2. Through the movable flange connection, installation, disassembly and transportation are convenient, shortening the start-up time and improving efficiency.
3. Good flexibility, tensile force, high strength and elasticity. The tube wall is folded in half and squeezed. It is not easy to break when affected by external force. The tubes are connected to each other and are easy to bend. 4-8 tubes can be bent 360 degrees on land. Connection, the area where the concave and convex surfaces are within 30 degrees can be directly connected.
4. The inner and outer walls are smooth and have strong wear resistance, which is 4-8 times that of steel pipes. It has self-lubricating properties, low friction coefficient, and higher transportation efficiency, which is 20%-30% higher than that of steel pipes .
5. It has strong corrosion resistance and remains unchanged in sea water and underground for 50 years.
6. Extremely resistant to ultraviolet rays and aging, and its service life is much longer than that of iron pipes, PVC pipes, nylon pipes and ordinary plastic pipes.
7. Movable flange connection, the entire pipeline does not have any welds, and the pipes are directly connected with bolts, which can ensure that it will not deform, break, or leak during long-term use, frequent installation and disassembly, and ensure efficient transportation.
8. The operating temperature is between -40 ℃ and 60 ℃, and it can adapt to harsh climate and temperature changes. Whether it is used for a long time in water or on land, the project cost is low, high efficiency and more convenient.

Connection method: flange connection, lining expansion, welded flange root, flanged integrated flange, etc.
