Ring Floats

Ring Floats and Pipe Floats


The design of the E+S floating collar system is based on a multiple float chamber principle. The floats are usable for pipes and hoses as well but there is a difference in the inner construction.

The floats are made of a very viscous Polyethylene to achieve the highest possible flexibility under the load of outer influences.

To guarantee the stability of the construction, the floats are equipped with a complex system of stiffening ribs. Furthermore, the bigger floating elements are filled with a closed-cell Polyrethane foam.

Depending on the dimensions, the floats will be assembled out of 2 or 3 elements. The connection of the single elements is made by Diolene-belts with stainless or galvanized special buckles.

We are also able to manufacture special forms of buoyancy bodies, as for example cable floaters or so-called head floats, for floating lines which dispose of one free end to be equipped with heavy connection units.

Mounting Instructions For E+S Pipefloats

An almost level surface (sand-covered) should be prepared for mounting E+S floating collars for pipes.

Two groups of floating ring halves should be placed in this area. The strapping belts have to be placed below the float halves into the built-in grooves.

Then, the steel pipe should be lifted into the floating collar halves. The remaining group of halves should then be placed on top of the steel pipe ensuring that the pin/holes should match with each other accurately.

Now, the strapping belts can be fixed by installing the buckles at one side with the short end of the belt. At the opposite side, the long end of the belt should be used for the clamping ratchet. The buckle should be positioned as far away from the next available axial groove, where the strapping tool can be handled, to have the longest possible distance to tighten up the belts.

After the floats have been fixed in this way, the retainer clamps should be installed at each side of the floating collar groups and then be tigthened up securely. To avoid the retainer clamps slipping on the steel pipe, it is recommended to tack weld on the outside of the retainer clamps to the steel pipe.

If mounting the floating collars on HDPE-/Julon pipes, the collars are fixed on the pipes by means of the integrated rubber plugs. In this case, the PE-floats are mounted in regular distances on the pipes to avoid bending of the pipeline due to one-sided buoyancy. The integrated rubber plugs in the floating collars assure a tight fit of the floats on the pipes and avoid slipping of the floating collars upon the pipes.

Pipe Float

Ring Floats and Pipe Floats


The E+S-pipe float system is a heavy duty floating device for steel pipes, HDPE-pipes a.s.o., which is manufactured to customer requirements.

The systems are designed benefiting from E+S's many years of skills and experience manufacturing floating hoses. The float design is dependent on using a highly flexible material to avoid cracking of floats during operation.

In detail the design are as follows:

  • high abrasion resistant, light-weighted HDPE-inner pipe
  • closed-cell Polyethylene foam buoyancy body built on it
    The advantage of PE-foam is that it is flexible and resilient enough to avoid cracking of cells in case of impact by a push-boat or any other equipment.
  • high abrasion resistant PU-skin (Polyurethane-skin), reinforced by several layers of high tenacity polyester fabrics to increase the tear resistance of the outer shell.
