Dredge MDPE Floater
Application
A dredge HDPE pipe, also known as a dredge high-density polyethene pipe, is a type of pipe specifically designed for use in dredging operations. HDPE (high-density polyethene) is a thermoplastic polymer known for its strength, durability, and resistance to abrasion, corrosion, chemicals, and UV radiation. By attaching dredge MDPE floaters to the pipeline or hose at regular intervals, the buoyancy is distributed along the length of the dredging system. This allows for efficient transportation of dredged material from the dredger to the designated deposition area.
Features
1.Good flexibility, excellent impact resistance, particularly suitable for constructions in open sea.
2.Easy to install and handle, lower costs for moving.
3.Higher corrosive resistance, longer working life, 3 times longer than steel floaters.
4.Lower costs, the cost performance is better than steel floaters.
