OS COR HIB A - Amine Based Corrosion Inhibitor
Oilfield tubulars and other downhole equipment must be protected from all types of corrosion when exposed to well fluids of any kind. Surface corrosion is a common cause of tubular failures and must be controlled at all times. Corrosion inhibitors should be applied to all fluids that have the potential to create a corrosive environment.
OS COR HIB A is a clear, dark amber liquid composed primarily of a mixture of aliphatic and heterocyclic mono-and diamines. OS COR HIB A is a water soluble film forming amine corrosion inhibitor used in solids free brines and packer fluids. OS COR HIB A can be used in calcium and zinc brines with temperature up to approx 160oC and 200oC in monovalent brine.
Typical Physical Properties
Appearance - Dark Mobile Liquid
Odour - Amine Type
pH (10% IPA) - 8 – 12
Flash Point - > 70oC
Solubility - Water soluble, oil insoluble
OS COR HIB A coats and protects the drill string with an amine film thus reducing the corrosive effect that carbon dioxide and hydrogen sulphide can create.
OS COR HIB A is intermediate in the preparation of corrosion inhibitors, emulsifiers, emulsion breakers, surfactants, thickening agents, and cement additives.
OS COR HIB A should, if possible, be tested under the expected field conditions, but if this is not practical then a dosage of 50-100 ppm is recommended.
OS COR HIB A is packaged in 200 kg drums or 1,000 kg IBC’s.
