Pipe Floats Used for Dredging, Mining, Aquaculture & More

Neptune™ is proud to be the leading manufacturer of pipe floats (a.k.a. Dredge Floats or Float Collars) in the United States. Neptune HDPE Pipe Floats are made from rotationally-molded polyethylene plastic with UV inhibitors to prevent the float from degrading over time.

Neptune Flotation Pipe Floats (Dredge Floats) are designed to the highest standard of safety and usability. Neptune Pipe Floats include features like Clamp Tite™ that prevent pipeline slips, EzGlide™ which allows wind and water to easily pass, and Snap-N-Lock—the solution to many float transportation and storage woes.

Pipe Float Features

Clamp Tite™ Helps Prevent Pipeline Slippage

Clamp Tite™ compresses and adds friction to prevent slippage along the pipeline. Neptune Flotation is proud to offer a solution to this common issue.

EzGlide™ Minimizes Wind and Water Resistance

Neptune floats are designed with tapered ends on the outside of the Pipe Float (Dredge Float) to decrease water and wind resistance. Tapered ends on the inside of float allow the pipeline to move freely.

Stack-N-Lock Makes Pipe Float Storage and Transportation Easy

Neptune Flotation includes built-in legs on the inside of all Pipe Floats (Float Collars) with corresponding molded-in recesses on the outside of the floats to allow for easy stacking while transporting or storing.

Floats with Ice Protection

Neptune Flotation offers a line of floats with Ice Protection, which are designed to withstand being frozen in place during harsh winter conditions. They have been successfully used in Canada and across the globe for many years. Neptune floats with Ice Protection are available to fit pipe sizes ranging from 2’’ to 36’’.
