Polyethylene encasement (polywrap) has been used since 1958 to protect ductile iron pipe from corrosion. It is the most popular, economical, and successful method for protecting pipe from corrosion.
A new advancement in polyethylene encasement called V-Bio® adds additional protection by inhibiting the formation of corrosion cells under the wrap. McWane Ductile added V-Bio® polywrap to its line of products in 2015. Adding a few steps to your pipe installation with V-Bio® is an Iron Strong decision that will benefit your pipeline for generations.
