    HVG DREDGING EQUIPMENT 0001: Dredge Floater

    Description of Dredge Floater

    Dredge Floater is made from polyethylene and polyurethane closed-cell foam.Dredge floater can be used for dredge steel pipe and dredge HDPE pipe.It is available for providing buoyancy for dredge pipeline.HVG dredge floater can be produced according to the specific design of dredging ship and the construction conditions of production.

    Polyethylene floater is currently popular floating material of dredger pipeline.It has various features,such as small volume,light weight,big buoyancy,wind resistance,aging resistance,long service life,etc.We mainly use medium density polyethylene material and high density polyethylene material.The hull of medium density polyethylene floater with excellent flexibility is filled with polyurethane foam.Its surface is smooth and wear-resisting.

    HVG Dredge Floater includes Dredge PE Floater and Dredge MDPE Floater.More designs can be customized according to clients’ specific requirements.For any more information,please feel free to contact us directly.

    Features of Dredge Floater
