The low-lying area of pipeline segments that are non-piggable are susceptible to collecting residual water which can lead to corrosion.

Zerust Oil & Gas has a liquid inhibitor injection procedure for layup. Zerust’s unique blend of Zerion Inhibitors is first mixed with water. In some cases, a vacuum truck may be used to mix the Zerust inhibitor with water. 

The inhibitor slurry is then pumped into ports in the higher elevations of the pipeline and allowed to flow to the lower elevations by gravity. Standing water is treated by the Soluble Corrosion Inhibitors, or SCI, slurry and neutralized. 

Vapor Corrosion Inhibitor (VCI) evolves from the slurry and neutralizes contaminant molecules in the atmosphere and on the steel surface. 

Soluble Corrosion Inhibitor (SCI) will neutralize the pH balance of the standing water at the bottom of the pipeline. 

The VCIs will volatize to provide continual protection of the annulus of the pipe until it is commissioned and begins service.

Do you have a pipeline in the pre-construction or pre-commissioning stage for which you need anti-corrosion solutions?
