Series 391 Tank Armor is a ...
Series 391 Tank Armor is a new chemical-resistant formulation developed by Tnemec and extensively tested for severe chemical immersion environments, according to Gary Zinn, Sales Director - Industrial Markets, for Tnemec."Series 391Tank Armor meets the requirements of customers in the oil and gas service industries, such as rapid return to service, one-coat application, fast-cure, high-build capabilities, ease of application and physical properties for long-term durability," Zinn explained.
"The roof and skirt are designed to travel (float) as the volume inside the tank fluctuates," according to Gary Zinn, sales director, Industrial Markets for Tnemec.
"No design has yet solved the persistent problem of rain water accumulation and ponding on top of the roof," Zinn
"This water combines with industrial and cooling tower fallout and escaped hydrocarbon vapor solutions which attack the substrate.
In addition to ultraviolet (UV) light degradation, roof and sidewall coatings are often subject to elevated temperatures for crude and distillate storage of 120 to 140 degrees F. It is easy to see that all exterior surfaces of floating-roof tanks should be regularly maintained."
Exterior steel on floating roofs is also subjected to salt-fog conditions found in coastal environments.
"It's estimated that in Louisiana's coastal environment, approximately 1.0 mil of protective coating material can be lost each year to erosion," Zinn
"So a dry film thickness of 16 to 20 mils is recommended to achieve a projected 20-year life cycle with proper maintenance."
"In meeting specification requirements of major oil companies and fuel jobbers, coating systems for floating-roof storage tanks must meet a range of performance criteria," Zinn
"Using this combination, total film thickness on the roof is approximately 20 mils," Zinn
The interior walls and floor areas are exposed to varying degrees of corrosion, from storage of sour crude (sulfur and salt laden), and higher vapor pressure volatile liquids.
"In the past, some engineers did not coat the interior surfaces with the belief that residues and a thin film of corrosion inhibiting petroleum will protect the surface from corrosion," Zinn
"This was proven not to be the case, even in those areas continually in contact with oil, because of the extremely corrosive nature of dissolved oxygen, hydrogen sulfide and naphthenic acids in some crude."
A design feature which greatly increases corrosion of interior surfaces is the freeboard area of the walls exposed by movement of the roof.
This zone may be alternately immersed in the product, physically abraded by the moving skirt, and exposed to the atmosphere as levels in the tank fluctuate.
"It is prudent to upgrade interior areas when maintenance pulldowns permit because inspection intervals can be between 10 to 25 years," Zinn
"Last year was a very depressed market because of falling commodity prices," recalled Gary Zinn, sales director, Industrial Markets for Tnemec Company, Inc.
With the current resumption of drilling activity, Zinn
anticipates increased market demand for maintenance supplies, such as lubricants, pressure valves, sections of pipe, seals, gaskets, connections and industrial coatings provided by oilfield supply houses.
"The 2HS is a very high solids version of Series 2H Hi-Build Tneme-Gloss," Zinn
"It's VOC compliant anywhere in North America except the Los Angeles basin, and is available in all oil field standard colors."
"Ease of application and performance on marginally prepared surfaces is especially important to the people who maintain these drilling rigs on-site," Zinn
"Product availability is also important.
Each drilling rig manufacturer has its own color designation, so it's critical to have the right products in the right colors available at a moment's notice in case a rig goes down and it needs immediate attention."
At recent meetings in Houston, Zinn
found a mood of optimism he
has not seen for several months.
"The oilfield is a very cyclic market," Zinn
