Introduction to Polywrap

In over 35 years of service in thousands of utilities in the USA and throughout the world, polyethylene encasement has proved an effective corrosion protection system for miles of ductile iron pipe. Today, it is the most widely used method of protecting ductile iron pipe installed in corrosive environments.

Polyethylene encasement involves simply wrapping the pipe with a tube of polyethylene immediately before installation of the pipe. It is easy for construction crews to install on-site and is by far the most economical way to protect ductile iron pipe. Also, unlike cathodic protection systems and bonded coatings, polyethylene encasement is a passive protection system, so it requires no monitoring, maintenance or supervision once installed.
