Thick-film elastomeric coating / lining systems have excellent performance characteristics in a variety of potable water lining work, including the polyurea spray elastomer technology. While some have cast doubt on the suitability of a polyurea system for immersion applications, there are a variety of commercial products with the NSF/ASNI-61 certification for potable water use that are performing quite well.

Thick-film elastomeric coating / lining systems have excellent performance characteristics in a variety of potable water lining work, including the polyurea spray elastomer technology. While some have cast doubt on the suitability of a polyurea system for immersion applications, there are a variety of commercial products with the NSF/ASNI-61 certification for potable water use that are performing quite well. Much of the myth around failures can be identified by improper specification work and incorrect material selection for the specific application.  Even though a proper system is selected and applied, improper surface preparation and / or spray application techniques can lead to application failures.  The same is true for other coating / lining technologies as well.  Having the proper training, material selection and proper guidance can lead to a successful application.  This paper will discuss a recent major concrete potable water storage tank lining application, the challenges faced; and the solution that led to success in Australia.

Moisture Vapor Emission Rates of Concrete Floors – Can Moisture Meters be used Instead of Calcium Chloride?

Product Number: 41212-666-SG
Author: George Holz, Kevin Brown
Publication Date: 2012
$20.00

The moisture vapor emission rate (MVER) of concrete floors affects the selection of flooring materials for both new construction and remodel projects. The MVER is determined by exposing a 20” x 20” test area to calcium chloride for 60 to 72 hours.

Durability Assessment of Foul-release Coatings

Product Number: 41212-715-SG
Author: David Tordonato, Dr. Allen Skaja
Publication Date: 2012
$20.00

The Bureau of Reclamation (USBR) is currently investigating the feasibility of using foul-release coatings to mitigate impacts caused by macro-fouling organisms such as zebra and quagga mussels.  Durability of these coatings must be considered as a factor in determining overall life cycle costs.  To this end, the Bureau of Reclamation has developed testing protocols to evaluate the durability of foul-release coatings with respect to abrasion, erosion resistance and the ability to overcoat existing equipment.

03126 PHYSICAL METALLURGY OF ALLOYS 718, 725, 725HS, 925 FOR SERVICE IN AGGRESSIVE CORROSIVE ENVIRONMENTS

Product Number: 51300-03126-SG
ISBN: 03126 2003 CP
Author: Sarwan Mannan, Ed Hibner, and Brett Puckett
Publication Date: 2003

Nickel-base alloys 718, 725, and 925 are commonly used in oil and natural gas production.  Being heavily alloyed multi-component systems; these materials require special consideration for processing and heat treatments.  This paper shows the effect of intergranular precipitates on mechanical properties and  slow strain rate (SSR) test results in sour oil patch environments.
