polyethylene float
Medium-density polyethylene floating body is currently a popular floating material for dredger pipelines at home and abroad. It has the advantages of small size, light weight, high buoyancy, wind and wave resistance, aging resistance, and long service life.
1. The structure and physical and mechanical properties of medium density polyethylene floating body
The shell of the medium-density polyethylene floating body is made of linear medium-density polyethylene plastic through rotational molding, and the interior is filled with polyurethane foam.

2. The earliest actual service life in China has reached 8 years, and it is still in use. Varies depending on the job situation.
The surface of the medium-density linear polyethylene floating body is smooth and wear-resistant. It can be dragged on the sandy beach by the sea without damage. The product is impact-resistant and can be filled with water from a height of 4.5 meters without breaking.
3. Installation of floating body
The installation of the floating body should use the backing plate, bolts and straps provided by the manufacturer. It should be tight and tight during installation. It is better not to deform the plastic. Double nuts should be used during installation. When installing, avoid sharp objects from piercing the floating body.
