Blue VB3® Enhanced Polyethylene is the newest addition to our lineup. AA Thread's VB3® Enhanced Polyethylene is a 3-layer co-extruded film. The film not only creates a barrier between corrosive soil and the pipe but is infused with an anti-microbial biocide and a volatile corrosion inhibitor (VCI), giving this wrap further corrosion-fighting capabilities than standard wraps. It also meets or exceeds all of the ANSI, AWWA, and ASTM standards required for Polyethylene Encasements.
The anti-microbial additive fights anaerobic corrosion caused by sulfate-reducing bacteria. This bacteria is the most important microbe responsible for anaerobic corrosion on buried ductile iron pipe systems. The biocide in our wrap will prevent the growth of bacteria on the pipe system. The VCI mixes with any corrosive liquids that might seep between the wrap and the pipe and neutralize them.
