Pre-Con is a liquid casing water conditioner for pipeline casings. It consists of "wetting" and filming agents, vapor phase inhibitors, alkaline media additives and antibacterial conditioners.
Pre-Con is poured into the casing prior to the installation of Trenton Fill-Coat Casing Filler. The method of using these two materials together is a Trenton Corporation patented process. Pre-Con conditions the water accumulated in the casing so that any small amounts of water that may be entrapped after installation of Fill-Coat casing filler are inhibited and no corrosion should occur.
