Most people understand the energy saving benefits of steam pipe insulation coatings pretty clearly. They are sprayed onto steam pipes, boilers, tanks and other surfaces to reduce heat loss and save energy. For example, Heat Shield™ EPX-H2O by Synavax™ can lower surface temperatures dramatically, over 100 degrees Fahrenheit with just two thin coats, and has been demonstrated to reduce the surface temperature from 393F to 231F, a 162F difference, with just 6-coats.
But there is another huge savings opportunity that’s not always as evident… Pinhole Leaks Can Cost More Than You Know! When a pinhole leak happens beneath traditional fiberglass steam pipe insulation or mineral wool with cladding, it can take days, weeks or more before it is noticed. Being hidden under this older insulation system means that the leak can remain undetected as the steam saturates the surrounding insulation, growing larger until finally discovered, then the whole insulation system has to be taken off and replaced while you try to find and repair it.
With Heat Shield™ EPX-H2O or Heat Shield™ High Heat the insulation doubles as an anticorrosive, so the coatings prevent the corrosion in the first place. In the unlikely event that there is a pinhole leak in the future, the whole steam pipe insulation system doesn’t have to be taken off and replaced. The steam will penetrate through the coating at the exact location of the leak and you can simply sand, grind or use a chemical remover on approximately a 3” to 4” circle around the leak, repair the leak, then just coat back over it when finished. Much easier and less costly.
