Abstract
Polymeric coatings are provided on steel pipes to protect the same against corrosion. Monomers and prepolymers are permanently adhered to the surface of steel pipes by graft polymerization to form a barrier which keeps out moisture, oxygen and other corrosive gases from the steel substrate. The monomers and prepolymers are chosen to provide a low moisture vapor transmission rate and oxygen permeability.
