Product information

Corrosion under insulation (CUI) results in billions of dollars in maintenance cost for oil and gas asset owners every year. The primary driver for CUI is the presence of water under insulation, but inspection for water and corrosion is expensive and is often performed with low accuracy.

Benarx WUI Drain Detection Plug is a drain plug designed to indicate the presence of water inside the insulation, in order to help asset-owners and maintenance planners to perform more precise inspection work for wet insulation and CUI. The WUI Drain Detection plug is equipped with a bright yellow indicator part which pops out if liquid water drains through the plug over a period of a couple of days.

The plug is a tool that helps pinpoint areas for inspection and thereby enables more precise risk-based CUI inspection which saves cost and time.

Benarx CUI Drain Detection Plug can be used for all insulation systems up to 180’C, but it cannot be used on cold-insulation if installing the plug means penetrating the vapor barrier. Furthermore, installation on fire-insulation systems requires that Benarx WUI Drain Detection plug is installed in combination with Benarx Fire Plugs which have been tested for integrity in fire.

The short version of the plug is recommended for fiber-type insulation materials while the long version of the plug is ore appropriate for rigid and closed cell insulation materials.
