coating, SureFlo[TM] internal coating and HeviCote[R] concrete weight coating.
The export pipeline and related tie-in pipeline contracts involve coating approximately 240 km of 14" diameter pipe that will be protected with three layer and asphalt enamel
anticorrosion coatings and concrete weight coating.
The contract involves the coating of 12 km of 28-inch and 10 km of 36-inch with asphalt enamel
and a concrete weight coating system.
It is very hard and stiff and is mixed with a filler material before coating to form an "asphalt enamel
." This enamel is applied between the steel pipeline's anti-rust coating and a thick concrete protection layer.
