Cortec VpCI®-639

Product Description

VpCI®-639 is designed to provide corrosion protection against the severe conditions encountered in petroleum production and refining. VpCI®-639 is effective for a wide range of refined hydrocarbons, crudes, and oil/water ratios. As a fast acting long-term corrosion inhibitor, VpCI®-639 forms an effective anti-corrosion barrier for metals in the presence of water, halogens, and corrosive gases such as dissolved oxygen, sulfur dioxide, carbon dioxide, and hydrogen sulfide.

Continuous protection between treatments is assured due to VpCI®- 639’s solubility, dispersibility in natural gas/water mixtures, and long-term water-displacing film formation. In addition, it provides vapor phase inhibition to protect areas inaccessible through direct solution contact. This unique characteristic protects internal parts during low fluid levels and combats atmospheric corrosion in production and storage tanks.

The unique chemistry of VpCI®-639 allows this product to provide excellent protection in sweet/sour (low or high hydrogen sulfide concentrations) environments at a very low concentration. VpCI®- 639 is very stable and will perform at elevated temperatures and in high-pressure environments without gunking. Temperature stability is maintained up to 400°F (204°C) and pressures up to 9,000 psi (621 bar) in sweet/sour systems. This product provides corrosion protection through the range of extreme service conditions encountered in natural gas applications.
