VpCI®-649 HP is nitrite-, phosphate-, molybdenum-, and chromate-free, ensuring an environmentally responsible solution.
Plumbing systems are essential to modern buildings, but new water lines face an often-overlooked risk: corrosion. During the early stages of construction, water lines must be hydrotested for leaks, leaving them vulnerable to corrosion over the 18-24 months it may take to finish the building. Indeed, the anticorrosion solutions supplier Cortec® Corporation offers a simple and effective way to avoid costly delays and additional cleaning with VpCI®-649 HP.
VpCI®-649 HP is a hydrotest additive from certified to meet ANSI/NSF Standard 61 for drinking water system components when used as a surface treatment at concentrations up to 3% and drained. When added to hydrotest water, it circulates through the piping system, preventing corrosion during pressure testing and forming a protective film that guards against corrosion for up to 24 months.
New buildings often feature diverse water line, for drinking and cooking, sanitation, fire sprinklers, and HVAC system, constructed with materials like steel, copper, galvanized steel and aluminum. In fact, VpCI®-649 HP excels in protecting all these metals – thus making it an ideal choice for multi-metal systems.
In addition, it features a PTSA tracer, allowing easy monitoring of its concentration throughout the process. Hydrotesting with Cortec’s VpCI®-649 HP at the start of a project ensures long-term corrosion protection, eliminating the need for additional cleaning and minimising delays.
