- Provide consulting and design service before sales, and provide scheme support to customers according to their working conditions and needs.
HDPE dredging pipes are molded by continuously extruded polyethylene through extrusion machines and designed molds. It has an excellent comprehensive performance, which contains high wear resistance, are light weight, easy to transport and install, do not require large mechanical construction, have excellent wave impact resistant and ring stiffness, have excellent tensile strength, can bear the shock of sea waves and win d, and come in customized pipe lengths according to the customer's request.
The HDPE dredging pipe has a low water resistant coefficient and small friction resistance, high transmission efficiency, good corrosion resistance, and h igh chemical stability. It is able to stand all kinds of corrosive medium and organic solvent of erosion within the scope of certain temperatures and the co ncentration range as well.
The HDPE dredging pipe is non-toxic and odorless, environmentally friendly and not liable to be corroded by armor shell and fungi from sea or sewage. It won’t produce incrustation and microorganism and has a high performance of resistance to low temperature , good aging resistance ,both in water and underground.
