CFCM Cortec VPCI33 400

Cortec has developed an alternative to nitrogen blanketing for void space layup corrosion protection.

Some real-life application examples are:
• Internal preservation of pig receivers en route from construction yard to offshore installation site;
• One-year protection of aboveground storage tank (AST) internals at a sulphur recovery plant;
• Temporary protection of fuel tanks in retired aircraft stored outdoors during museum renovation;
• Protective packaging element used for shipment of horizontally-opposed piston aircraft engines.

To prevent corrosion inside void spaces of idle equipment or permanent structures, Cortec Corporation has recently announced the development of VpCI-337, a time-tested alternative to nitrogen blanketing specifically intended for the oil and gas industry, as well as all the other sectors that deal with metal tanks, piping, boilers, heat exchangers, hollow metal structures and hard-to-reach areas between the layers of metal coils.
Usually, nitrogen purge or nitrogen blanketing protects metal void spaces from corrosion by replacing the oxygen with nitrogen gas. However, nitrogen gas is expensive and requires constant pressure with an airtight seal that needs regular monitoring and complete reapplication in case of leaking. In addition, leaks also pose a safety hazard for personnel. Cortec has then developed VpCI-337, a safer, cost-effective and easy to apply and maintain waterborne Vapor phase Corrosion Inhibitor that can be applied by fogging into metal void spaces.
The new labour-saving technology uses a minimum of products to protect large volumes. Vapour phase Corrosion Inhibitors in the fogging fluid diffuse throughout the void and attract metal surfaces. They form a protective molecular layer that inhibits the corrosion reaction on the metal surfaces, even in oxygen residual moisture.
Furthermore, the company’s new product is very versatile. It can provide corrosion protection for everything from massive heat recovery steam generators to small crates of metal parts.

CFCM TeknaGun 400

Carlisle Fluid Technologies’ DeVilbiss TEKNA spray gun was recently featured on an episode of Detroit Muscle on Power Nation TV to bring a 1973 AMC Javelin back to life. Featuring a high finish quality and operator ergonomics, The TEKNA gun’s high transfer efficiency provides materials savings for solvent or waterbase paints.

The spray gun technology, which has been used in automotive refinishing processes for many years, is designed to spray all types of materials and comes with high efficiency or HVLP air caps that produce large spray patterns with even material distribution.

New Bacharach Sling Psychrometer

CFCM slingpsychrometer 400Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.

As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.

The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart.
