Cortec VpCI®-619 Undercoating for Insulated Surfaces

Product Description

VpCI®-619 is a water-based corrosion inhibitor designed to protect against corrosion under insulation (CUI) in high temperature applications up to 1100 °F (600 °C). VpCI®-619 can extend the life of piping and insulation in refining, petrochemical, and marine environments thus minimizing replacement material and labor costs. The product is non-corrosive and non-flammable, so it can be applied and used safely in widely varying conditions.

A typical and extremely useful application is the protection of insulated steam or hot oil pipelines. Moisture trapped beneath the surface of the insulation can cause corrosion that is difficult to detect. If unnoticed and untreated for too long, this corrosion can result in potentially disastrous leaks with costly damage.

To discourage CUI, VpCI®-619 should be sprayed on the inside of insulation before it is wrapped around new pipes or other metal surfaces that need to be insulated. VpCI®-619 may also be applied to existing pipes when corrosion is found during maintenance. If the integrity of the pipe is not compromised, the pipe may be cleaned and wrapped in new insulation treated with VpCI®-619 to provide future protection.

Features

• High temperature resistance up to 1100 °F (600 °C)
• Non-flammable
• Protects in wet and dry cycles
• Long lasting

Benefits

• Inhibits CUI on pipes and other insulated metal surfaces
• Reduces frequency of maintenance and repair related to CUI 
• Increases overall plant safety by reducing dangerous corrosionrelated failures

Application

VpCI®-619 should be applied to the insulation prior to wrapping or coating pipes. Mix thoroughly prior to use. Product should be spread at a rate of 150 – 200 ft2 per gallon (3.68-4.9 m2/L) on insulation. For best results, pipes or metal surfaces treated with VpCI®-619 should be protected as soon as possible with either an insulation blanket or similar pipe wrapping. VpCI®-619 is light and powder-like once dried.

Possible applications include insulated piping or exhaust manifolds in

• Power Plants
• Refineries
• Ships
• Offshore Rigs
• Other Industrial Facilities

Metals Protected

• Carbon Steel
• Cast Iron
