Abstract
This paper will review what a 2-layer polyethylene coating consists of, the application and use as an external mainline coating for both ductile iron and carbon steel pipe. Laboratory data will be reviewed regarding UV aging and thermal and hydrolytic aging and mechanical properties. Examples of field installations will also be discussed. Case histories regarding long term in-ground performance of 2-layer polyethylene plant applied external corrosion coatings will be discussed.
