Dredging pipeline&floats

Relong Floats are designed to be applied on HDPE or steel pipe.

The dredging floats are composed of two halves made in UV-stabilized linear virgin rotomoulded polyethylene.

?

The Polyethylene used in the manufacturing process is completely recyclable (Eco-Friendly), it's fully compatible with the marine environment, and has a high resistance to UV rays.

Being linear has the advantage that it can be melted and hence repaired by hot fusion welding.

The color pigment is molded-in and consequently not added as a coating ensuring greater life of the color and a big help to the environment as it never requires additional paintings, avoiding toxic dispersions in the water.

Floatex polyethylene requires minimal maintenance.

R&D laboratory daily performs tests on production samples such as tensile test, hardness test, abrasion test, UV test, and Cold temperature test, color test, and other ordinary tests in the aim to ensure the quality and the reliability of Floatex products.

The floats can be filled with closed-cell polyurethane foam with different densities in the base of the hydrostatic pressure the floats need to withstand.

The polyurethane foam ensures great resistance to the leakage of air or water, ensuring unsinkability to the buoy also in case of accidental breaks of the outer shell.

The polyurethane foam is 100% made and tested before production by our R&D laboratory.

The two halves are connected to each other on the pipe through four steel bolts, two on each side to ensure optimal clamping with the pipe.

For certain applications, for surface use only, the floats can be supplied also empty, without inner filling.

Floating pipelines are either formed of steel pipes supported at regular intervals by buoyancy units or surrounded by a buoyant case, or they are composed of pipes made of a buoyant material.

In all these cases the pipeline must be built to be flexible enough to endure the movement of the sea and currents. The pipe itself may be made flexible by inserting ball joints in the line at regular intervals or by adding lengths of flexible pressure hose. All floating pipelines are made in a modular fashion and are connected together by bolts or quick coupling devices.

During the best cooperation, we can make sure the floating pipeline is half on the water and half under the water, the balance makes the dredging work easy to finish.
