Dredge Pipeline

1.What are the main types of dredge pipelines?
Dredging hose mainly includes flange type dredging rubber and suction type dredging rubber hose.
Flanged dredge pipelines are easy to pipe connections and reduce wobble caused by waves. Make the medium more smooth in the Dredging pipelines.
Dredge pipelines
Features: It has wind and wave resistance, corrosion resistance and good self-floating performance, high working pressure, long service life, easy assembly, etc.
Features: One-time molding without welding seam, fully enclosed, corrosion-resistant, anti-aging, strong impact and collision resistance; the inner filler is polyurethane foam, one-time molding, not easy to break, especially suitable for construction in working waters with large wind and waves;
Uses: Mainly used for dredging and conveying pipelines in oceans, rivers and lakes.
2.What is HDPE Dredge pipelines？
The material used for the dredge pipeline is HDPE.
HDPE Dredge pipelines are made of high-density polyethylene, a thermoplastic resin. The Dredge pipelines themselves are strong and have a smooth black surface. Since its raw material is HDPE, the pipe has excellent chemical resistance and corrosion resistance, which effectively prolongs the service life. In addition, Dredge pipelines can withstand different hot and cold temperatures with almost no deformation. In addition, the Dredge pipelines requires little post-maintenance, thus saving you money. There are a variety of pipe diameters and pipe diameters to choose from to meet different water delivery needs. 
3.What are the characteristics of HDPE Dredge Pipelines？

①. Non-toxic, HDPE material is non-toxic and tasteless. It has passed strict sanitation testing. It is a green building material and will never scale, which can effectively improve water quality.
②. Low flow resistance. Smooth inner wall for easy piping. Under the same conditions, the conveying capacity of HDPE Dredge Pipelines can be increased by 30%, and its roughness is much smaller than that of steel pipe and glass steel pipe. HDPE Dredge Pipelines have a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water conveying.
③. No leakage. HPED Dredge Pipelines are connected by butt welding, socket welding, electrofusion, etc. The strength of the connection point is higher than that of the pipe itself.
④. Excellent flexibility. Small diameter HDPE Dredge Pipelines can be rolled into discs. At the same time, large-diameter products can also be slightly bent, which is more convenient on the construction site. The flexibility of the HDPE pipe makes it easy to bend, and the engineering can bypass obstacles by changing the direction of the pipe. In many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and installation costs.
⑤. Good scratch resistance. The wear resistance of HDPE Dredge Pipelines are 4 times that of steel pipes, which means that HDPE Dredge Pipelines have a longer service life and better economy. HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its resistance to environmental stress cracking is also outstanding.
⑥. The construction is convenient, and the Dredge Pipelines can be constructed and installed by various non-excavation methods.
⑦. Long service life. Under the constant temperature and pressure design, the service life can reach 50 years, and it will not be damaged by ultraviolet radiation.
⑧. Good chemical corrosion resistance: HDPE Dredge Pipelines are resistant to corrosion by various chemical media, and the chemicals present in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote algal, bacterial or fungal growth.
⑨. Reduce operation and maintenance costs. HDPE Dredge Pipelines are lighter than concrete pipes, galvanized pipes and steel pipes, it is easy to handle and install, and lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced. HDPE Dredge Pipelines are not only convenient to transport and install, but also greatly reduce the labor intensity of workers and improve work efficiency.

Milestone dredger company was established in 2010, after a decade development and growth, our company successfully exported equipments to Nigeria, Kazakhstan, Chad, Indonesia, Philippines, Thailand, Maldives and other countries and regions. Especially the hydraulic cutter suction dredger for inland river dredging is widely recognized and praised by the customer.
