Hydrophobic Piping
Hydrophobic Piping
(OP)
Does anybody have experience with pipe having inside coated with hydrophobic material? This videoLink shows flow through untreated, hydrophilic and hydrophobic pipes. It seems using this kind of pipes (inside hydrophobic) reduces pump size and consumed energy. Isn't it?

The material has been proposed for condiments such as ketchup, but I don't think that it has been commercialized yet.
It is probably too expensive for industrial fluids at this stage.

There is a fair amount of global experience with polyolefin pipe of one sort or another, but I haven't noticed enough of a difference vs. other materials to go changing pump sizes.

There are many competing technologies undergoing research.
Multiple patents have been issued for various technologies:

LiquiGlide showed three slippery surfaces: teflon, superhydrophic surface and oil. They claimed that LiquiGlide is a better alternative than the three because it removes nearly all liquid without interfering with the consistency. First, the porous solid which is on the surface of the product. On the porous solid is the impregnating liquid and the product's liquid would be on the impregnating liquid. The LiquidGlide coating is like a lubricant in that a permanently wet layer that is designed to be super slippery. Essentially, the end product is resting directly on a layer of liquid.
