Description
Pre-Con® is being poured into the casing through the casing vent. 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.

End Use
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.

Application Procedures
Prior to the filling operation, Pre-Con is poured directly into the casing through the casing vent and mixes with any water accumulated inside the casing. The casing can then be filled with Trenton Fill-Coat Casing Filler.

Packaging
Pre-Con® is packaged in one-gallon pails or it is provided in bulk at the job site when Trenton crews install Fill-Coat®
casing filler.
