VpCI-649 Series Corrosion Inhibitors – Cortec Corp.
ST. PAUL, Minn. — Hydrostatic testing simultaneously solves a problem and creates one, and so does closed loop or cooling water system layup. In the first case, the introduction of high-pressure water to a pipe, valve, or tank confirms no leaks exist, but it elevates the risk of corrosion. In the second case, while closed loop or cooling water system shutdown is sometimes needed for seasonal periods of inactivity, it leaves equipment vulnerable to corrosion if proper precautions are not taken. Fortunately, these tasks can successfully be carried out with the ease and effectiveness of VpCI®-649 Series corrosion inhibitors from Cortec® Corp.
The VpCI-649 Series encompasses a range of unique concentrated liquid formulations that protect ferrous and nonferrous metals from corrosive solutions such as hydrotest water. They are also designed to provide long-term protection in fresh water and glycol closed loop systems. VpCI-649 combines contact and Vapor phase Corrosion Inhibitors — along with antiscalants for hard water stability — in a formulation that does not contain nitrites, phosphates, or chromates. This helps solve the problem of disposal, particularly for large quantities of water. For those facing tightening molybdate restrictions, the VpCI- 649 Series includes molybdate-free versions with a PTSA tracer for easy detection.
