Slurry pipeline Floats

Slurry pipeline – a pipeline, used to transport slurry (a mixture of water and soil or rock, obtained by excavating and mining hydraulically) with hydraulic dredger equipment to the point of discharge. 
Floating slurry pipeline. Its purpose is to connect the working dredge to the shore slurry pipeline. The slurry pipeline allows operating maneuvers; it is the supporting structure for securing the supply and control cables, moving the staff to the dredge ship or ashore. The installation of floating slurry pipelines is made on special floats,the number of which depends on the length of the pipeline.

* Only bigger part is filled with Polysterene, but Float 420-650 has both parts filled.

We produce polyethylene floats to maintain the slurry pipeline on water. It is also possible to use our floats as floating bearing elements for any purpose. Operating temperature is from -40°C to + 60°C, UV resistant.

Along the floating slurry pipeline a gangway for the staff and high voltage cables for charging an electric dredger are usually laid.


Unique design, accepting any pipe from Ø100 mm to Ø650 mm

It is possible due to top part of float adjusts to the tube height and pushes the pipe tightly to the lower part of float:

Therefore our range of floats for slurry pipeline can accept any tube with diameters 140-650 mm.

Float is fixed by straps or belts

Why choose our floats:

  • Filled with EPS (Expanded Polystyrene) 25
  • Module maintains it`s shape and is resistant to mechanical deformations
  • Compared to air-filled modules, our module retains floatation properties in case of hole
  • Fast to mount
  • Operational temperature from – 60°C to + 60°C
  • Environmental friendly​

Pontoons for Heavy pipes

When Pipeline is too heavy to be held using conventional floats, we offer a Modular Pontoon 1500 as a floating base.

This solution is most popular for:

  • Steel pipes
  • Pipes that require gangway alongside

Based on weight of pipe (desired load capacity) and required gangway width, Modular Pontoon 1500can be placed along or across pipeline. Rails can be placed on one or both sides.

Advantages:

  • Long life, as PE is not susceptible to corrosion
  • Cheaper compared to solutions on steel pontoons
  • Max. load capacity is 800 kg/m
  • Product shipped as separate Modular Pontoon 1500 (3×1.5m). Fast assembly at installation place by strengthening chains Video.

Order custom float (i.e. floats with inner diameters >650mm)

Float for pipe Ø850mm

We are full-cycle rotomolding producers. This means that our supply chain has stages such as (computer 3d model design, development of prototype, mass production and quality control).

Today we are interested in extending our range of floats. We welcome our customers to ask for custom products and promise to offer reasonable price-quality-time ratios.

It is possible to order the design and manufacture of floats for all pipeline diametres based on both sketches or drawings of the client, and without them.
