en.Wedoany.com Reported - Vanconol, a brand under Tianjin Hephilay New Materials Co., Ltd., has introduced a comprehensive corrosion inhibitor product solution covering the entire process of oil and natural gas extraction and refining, targeting equipment corrosion challenges in the petrochemical industry. According to statistics from the China Petroleum and Chemical Industry Federation, corrosion causes economic losses exceeding 20 billion yuan annually to domestic petrochemical enterprises. Leveraging its proprietary imidazoline technology platform, Vanconol promotes localization through independent innovation, aiming to provide long-lasting and stable corrosion protection for oil and gas equipment.
The petrochemical production environment is complex, with equipment facing corrosion types primarily including high-temperature sulfur corrosion, carbon dioxide corrosion, chloride ion stress corrosion cracking, and hydrofluoric acid corrosion. To address different operating conditions, Vanconol has developed the Refining Corrosion Inhibitor Series (RF Series), the Oil and Gas Wellbore Corrosion Inhibitor Series (ET Series), and the Specialized Metal Treatment Corrosion Inhibitor Series. The RF Series refining corrosion inhibitors include RF-401 (water-soluble, used for delayed coking, hydrogenation unit fractionators, and stripper overhead systems, with rapid film formation, low dosage, and high inhibition efficiency), RF-401N (water-soluble, used for neutralization and corrosion inhibition in atmospheric towers, primary towers, and vacuum tower overhead systems, with rapid film formation), RF-401W (water-soluble, economical version), RF-402 (water-soluble, used for fractionator and stripper overhead systems, with dense film formation), RF-402W (water-soluble, economical version), RF-403 (oil-soluble, used for delayed coking, hydrogenation unit fractionators, and stripper overhead systems), RF-403W (oil-soluble, economical version), and RF-501 (water-soluble, for high-temperature and high-pressure environments).
The ET Series oil and gas wellbore corrosion inhibitors cover full-process corrosion protection from downhole to surface, including ET-101 (oil well corrosion inhibitor, suitable for high H₂S/CO₂ environments), ET-102 (gathering and transportation corrosion inhibitor, with stable film formation), ET-103 (produced water corrosion inhibitor, resistant to chloride ions), and ET-105 (acidizing corrosion inhibitor, resistant to acid and high temperature). The Specialized Metal Corrosion Inhibitor Series targets different materials, including CPI-42 (copper and copper alloys, pH range 5.5-10), CPI-AP (multi-metal universal), IR-901 (steel, preventing over-corrosion and hydrogen embrittlement), ALI-910 (aluminum alloy, environmentally friendly formula), ALI-1214 (aluminum alloy, suitable for electronic equipment), and MGR-82 (magnesium alloy).
Vanconol's full product line relies on its proprietary imidazoline intermediate technology platform, forming four major series: oil-soluble, modified, water-soluble, and quaternary ammonium salts. The products utilize self-assembled film formation technology, with a single addition maintaining continuous corrosion inhibition effects for over 30 days; through molecular structure optimization, the effective concentration is reduced by more than 50% compared to traditional products. The formulations are free of heavy metals such as chromium and cadmium, and offer both water-soluble and oil-soluble series, compatible with demulsifiers, drag reducers, and other additives, flexibly adapting to different unit characteristics.
Founded in 2010, Tianjin Hephilay New Materials Co., Ltd. is a national high-tech enterprise headquartered in Wuqing District, Tianjin. It has a controlled subsidiary in the Liaoning Panjin Fine and Petrochemical Industrial Park, covering a 61-mu industrial area. The company's R&D team comprises multiple doctoral and master's degree holders, establishing a complete imidazoline intermediate synthesis and application technology platform. The Vanconol brand has formed a complete product chain from monomers to end products, with exports to over 30 countries and regions including Southeast Asia, the Middle East, and Europe.
