CORROSION CONTROL THROUGH MICRO-POROUS DRY TECHNOLOGY Rust is caused by the influence of water, oxygen and time. Air pollution and contaminants on steel surfaces speed up the corrosion process. When corrosion is caused by condensation water, a micorporous coating can considerably enhance traditional corrosion protection in 4 distinct ways: 1. It delays the forming of condensation on the surface 2. It absorbs the condensation into the...

NorØrn The Problem Modern fishing boats are more or less floating food-processing factories. Most of the North European and Canadian fishing fleets operate in arctic waters, where the outdoor temperatures can be very low; -30°C or below. The climate inside the ship is room temperature and the relative humidity, RH, is generally rather high due to the processing of fish. It is unavoidable that vapour...

Kristian Gerhard Jebsen Skibsrederi use Kefa in their Gear Bulk ships for transportation of paper and pulp. The first series of three bulk ships were built in 1990/91. When in 2000 a new series of similar ships were to be built Kefa was specified as condensation protection, due to the good experience of the product. The Problem Paper pulp release large quantities of water during the transport. This water condenses in the roof of the...

The treatment was undertaken in February 2005. The problem Water supply plants generate large amounts of water vapor that condenses on the water tanks, pipes, pumps and other equipment. Water Supply Berlin was built in the 50-th and had deep-seated rust and other severe corrosion problems. The equipment has been repainted several times but due to the damp environment the corrosion was soon back again. A special problem was that condensation...
