Use and quality standards of the pipe float

Dredging floats are commonly used in dredging projects and sea reclamation projects around the world. They are used for dredging pipelines, sand pumping pipelines, sand pumping vessels. They are mainly used for dredging vessels in the ocean, rivers, and lakes, etc. let’s understand the use and quality standards of the pipe float.

Use of the pipe float

1. Ensure that the pipeline floats on the water;
2. The orange-red appearance color can be used as a warning sign to prevent hitting the pipeline;
3. Convenient for the inspection and maintenance of the pipeline;
4. Shorten the construction period, reduce the cost, and reduce the maintenance cost.

Quality Standards of the pipe float

In the actual use of the dredging pipe float, the following five inspections should also be carried out on the pipe float (buoyancy, overall weight, plasticization degree of the plastic shell, the density of the inner foam, and foam cells of the pipe float) to judge the quality of the pipe float.

1. The buoyancy of the pipe floater: Generally, it is required to be greater than 30% of the weight of the pipeline itself (including the mud with a specific gravity of 1.3). When the pipeline is working, the height of the exposed water surface is about 1/4 of the height of the steel pipe;

2. The overall weight of the pipe float: not less than 3-5% of the order parameters. Because the weight of the pipe float is related to the weight of the pipe float’s shell, and the specific gravity and volume of the pipe float’s foam. For a pipe float that is too light, the strength of the plastic shell and the specific gravity of the foam are difficult to guarantee. The specific gravity of the foam should be about 35 kg/m3.

3. The degree of plasticization of the plastic shell of the pipe floats: the inside of the plasticized pipe floats should have a smooth surface without obvious particles. At this time, the plastic shell has the best tensile resistance;

4. The density of the filled foam: generally should be about 35 kg/m3, the tensile strength at this time is about 0.2MPA; slightly elastic, non-sticky and not brittle is qualified; only the dredge floats that guarantees the above product standards are the same Really durable and good floating body;

5. Floating body foam hole: the welding must be firm, and repair welding should be done when there is a leak.

The pipe floats are of great significance to dredging projects and other undertakings and have made great contributions to water transportation operations. Attention should be paid to the material and workmanship of the pipe float. Only ensuring the quality of the pipe floats, can play a greater role in dredging projects.
