en.Wedoany.com Reported - Cortec's VpCI-649 HP hydrostatic test corrosion inhibitor has received ANSI/NSF Standard 61 certification, providing corrosion protection during potable water pipeline pressure testing. The product is sold through Savcor Products Australia in Australia and New Zealand.

Potable water pipelines, fittings, and vessels require hydrostatic pressure testing after installation, before initial commissioning, and after repairs or shutdowns to check for potential leaks and confirm the system can withstand operating pressure. However, water used for testing may leave residual moisture after drainage, potentially causing corrosion issues before occupancy. To address this challenge, Cortec launched VpCI-649 HP in 2023. When added to test water at concentrations up to 3% and then drained, this inhibitor is certified to comply with ANSI/NSF Standard 61 (Drinking Water System Components). This allows contractors and plumbers to perform hydrostatic testing on potable water pipelines and tanks without exposing the system to corrosion during construction delays.

VpCI-649 HP protects multiple metals including steel, copper, galvanized steel, and aluminum, covering surfaces both above and below the waterline (vapor phase and contact protection). The formulation is free of nitrites, phosphates, molybdenum, or chromates, and application can be verified using a PTSA tracer. Key product advantages include multi-metal protection, comprehensive coverage, environmental responsibility, and easy verification.
