Not surprisingly, despite floods, storms and Hurricane Harvey, the bare metal substrate remains completely free of corrosion and previously corroded areas can be wiped clean of rust.

More proof of how good Enviropeel is at corrosion prevention has just come from our Texas and Louisiana distributors, Corrosion Coatings Systems.

They tested Enviropeel at an access well located on a Colonial Pipeline site in Orange, Texas bounded by petrochemical plants and brackish waters which periodically submerge the substrates during large storms and hurricanes

The application was completed in October 2016 and followed by a series of inspections at 3-months, 8-months and 21-months post-application

During this period Hurricane Harvey caused the entire area from Beaumont to Houston to be flooded, submerging one of the test flanges.

Two areas were coated, a 36″ blind flange and a 12″ blind flange in a soil-to-air interface.

Prior to application, on the larger flange, an area of the flange and an adjacent nut surface were abraded to reveal the bare steel beneath the coating.

As both test pieces were already suffering from corrosion prior to the application, these areas were cleaned of all previous coating and rust to highlight the effectiveness of the rust protection.

The application was over the entire flange but the test areas were examined by cutting away a small area of the coating, testing for any signs of corrosion and then replacing the removed material, resealing it into the coating using a standard electric heat gun.

Not surprisingly, despite floods, storms and hurricanes, the bare metal substrate remains completely free of corrosion and previously corroded areas can be wiped clean of rust – the substrate looks better after 21 months than it did before application!

On the smaller flange, the same test intervals were applied. You can see from the first pic that it was extensively corroded before application. 

At each interval the test area could be seen to be completely free of any additional rust. 

The final cutaway after nearly two years and extensive flooding shows that, despite the environmental deposits on the outside, the interior of the coating and the flange face remain absolutely uncontaminated.
