Supporting a rigid 140mm PE pipe in water 2

[slippydog]

Hi Guys

I've got a lagoon which is approximately 30m in length, into this lagoon flows a 3 x 140mm PE pipes which will contain only a small amount of sludge. Is there anyway I can support these pipes on the surface of the water with say for example 5nr 1m x 1m pontoon or some other bouyancy device considering the pipes are rigid?!

I can't place anything on the banks of the lagoon as this is potentially unstable I looking for the cheapest and most efficient way of doing this and any help would be much appreciated.

I forgot to mention that the lagoon is cleaned out once a year so whatever solution I reach it needs to be fairly easy to remove.

Q. 19 Will HDPE pipe float in water? Yes, HDPE pipe, due to its density being slightly less than water, will float even when full of water. When it is desired to ensure flotation of the line, various forms of collars, saddles, and strap-on flotation devices are available. Refer to Chapter 10 of the PPI Handbook of Polyethylene Pipe, 2nd ed.

You could use pre insulated PE. The PE has a PU foam covering and PE sheath. his will float without any problems.
