It features high-solids, single-coat, fast cure technology. Enviroline 58HS enables users to hold surface preparation for up to 90 days while still meeting VOC requirements. Improvements to Enviroline R 58 and Enviroline R 59 include easier mixing, lower VOCs, no need for special thinners, and color changes. In establishing the cure of any lining system, a rub with a MEK wetted clean, white rag works well as an indicator of solvent resistance.
Riveted tanks present a special set of sealing and lining difficulties. Enviroline ultra-high solids, thick-film epoxy coating exhibits chemical- and solvent-resistance in addition to abrasion- and impact-resistance.
This should provide information about the structural stability, shell plate movement, gaps in seam overlaps, missing rivets, etc. Enviroline 58 is now available in tan for greater contrast from IECC topcoats, and Enviroline 59 is lighter color to increase hiding ability of Envirothane TM Urethane topcoat. Many lining failures can be directly attributed to primer applications that have filled in the blast profile. Pipe may be backfilled as early as 5 to 7 minutes tack free. Where possible, rivet seams should be sealed from the interior of the tank.
If necessary, additional cleaning steps will be needed to eliminate this condition. Old tanks, upon coming out of service for refurbishment, present a wide variety of steel substrate conditions. Notes on Lining Tanks. Applications include large tanks requiring surface preparation and situations where humid environments exist. Hardness gauges can be used as a more accurate and quantitative indication of cure, but, as it pinpricks the film, this must be considered a destructive test procedure.
A Heavy-Duty system applied at In establishing the Dry Film Thickness for any lining system, be aware of the need to rely on a statistical average, as DFT varies often widely from place to place in a tank. Be aware of any other pertinent factors, such as abrasion or temperature.
Since most linings are tested as soon as practical, much sooner than at full cure, and since significant under-specified DFT readings are allowable within reason and providing the specified average is met 70 volts per mil of coating has been found to be thorough enough for adequate testing, while not causing harm to a freshly applied coating.
Offering thin-film application of up to 20 mils DFT, Enviroline UHS is suited for use as internal lining for storage tanks, process vessels, pipelines, and concrete containment structures requiring corrosion protection from refined petroleum products and chemicals. Some tanks may not be suitable for integrity restoration using these linings.
This step lessens the risk of re-contaminating the primed surfaces when proceeding with the final blast work. Areas of use include oil Thomas Industry Update Stay up to date on industry news and trends, product announcements and the latest innovations. Explosives, Armaments, and Weaponry.

An inspection blast conforming to SP-6 Commercial Blast is usually sufficient and also serves to help with an assessment of metal loss and pitting. Pompano Beach, FL Share: A Handy Checklist for a Successful Lining The first step of a successful lining application is to ensure the proper coating is selected, one that will withstand the anticipated service. The company has installed more than 25 Enviroline units since October and has been a strong proponent of the technology for It offers fnviroline and applicators choice of application speed and curing results without envirokine quality of chemically resistant barrier.
For example, a two-coat thin film system typically mils would be a poor choice for severely pitted plates. All tanks, prior to abrasive cleaning, should 3766 tested for the presence of hidden contamination, especially chlorides. Extensive pitting, especially deep and convoluted pitting cannot be easily coated by such systems.
When sealing riveted exteriors, it is most often necessary to lower the content level in the tank to avoid problems with seep spots. It does not require preheating prior to enviroine and is suited for tank and pipe owners as well as contractors.
Consult Avilion to verify the suitability of any 3776 coating. Company News Blount Rd. A Handy Checklist for a Successful Lining. Enviroline 58 is epoxy polyamide rust inhibitive primer; Enviroline 59 is for Holiday testing should be performed using a maximum of volts per mil of applied, fully cured coating.
This system can be envirooine in lieu of more labor intensive and costly ebviroline lay-up and chopped fiberglass systems see our site Reinforced Tank Linings. It resists combination of water with high-temperature oil or gas. Adequate cleaning must be employed to avoid previous tank contents from seeping out of rivets, seams, butt straps, etc.
A chemical resistant epoxy primer like Enviroline 58HS applied at 0. A holding primer should be applied to the blasted steel within an 8 hour period to protect it from re-rusting.
