How to setect the high quality of floating bodies?

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

2、 The overall weight of the floating body: not less than 3-5% of the ordering parameters, because the weight of the floating body is related to the weight of the floating body's shell, the specific gravity and volume of the floating body's foam, and it is difficult to guarantee the strength of the plastic shell and the specific gravity of the foam for the floating body whose weight is too light. The specific gravity of foam shall be about 35 kg/m3.

3、 Plasticization degree of floating plastic shell: The interior of the plasticized floating body should have a flat and smooth surface without obvious particles.

4、 Density of filled foam: generally about 35kg/m3. The tensile strength at this time is around 0.2 MPA. Slightly elastic, non sticky and non brittle are acceptable. Only floats that simultaneously guarantee the above product standards are truly durable and good floats.

5、 Floating foam hole: The welding must be firm, and repair welding should be carried out when there are leaks.
