1 Supplement to CoatingsPro Magazine SUMMER 2012 What a Great Time to be a NACE-Certified Coating Inspector By Malcolm McNeil, CIP Committee Chair The economy is slowly getting stronger but there is still too much unemployment with a lot of people having some tough times. Some sectors of the economy are robust and strong while others are weak and having a hard time getting back to pre-2008 levels. The oil business remains one of the strong sectors. Pipeline companies and oil companies are specifying NACE-certified Coating Inspectors as they understand the value of third-party coating inspection. When I look at the numerous forums on the Internet relating to oil and pipeline companies, I see ads for NACE-certified Coating Inspectors at all three levels. The need seems to be widespread with requests coming from North America, South America, the Middle East, and the Far East. The demand is primarily for NACE Coating Inspector Program (CIP) Level 2 and 3 Coating Inspectors, with some looking for Level 1 inspectors to work under the supervision of Level 3 inspectors. For those of you who have NACE CIP Level 1 and Level 2 certification, you will probably never see a better time to sign up and get your next level of certification. NACE is offering CIP courses in many locations around the world so there is plenty of opportunity to advance your level of certification. Coating inspection work is available in abundance for those who are willing to travel to project locations, and the salaries can be lucrative. NACE recently completed its 14th annual Corrosion Career Survey, which includes average salary levels by NACE certification in North America and Europe. The article beginning on p. 2 provides highlights of this year s survey. We are in the middle of another painting season and maintenance painting is at its peak. Bridge painting is going strong and state departments of transportation also know the value of NACE-certified coating inspection. We have all read the stories and heard the comments on the news about the condition of the infrastructure in the United States and other countries. Owners in the government and the private sectors are realizing, as never before, the value of coatings in protecting their assets. This means more coatings projects in the coming months, and more coatings projects means more opportunity for NACEcertified Coating Inspectors. Yes, it is a great time to be a NACEcertified Coating Inspector.! IN THIS ISSUE...

Summer 2012 The NACE Corrosion Network A Free Technical Resource Take advantage of the knowledge of thousands of corrosion experts in every industry by joining the -based NACE Corrosion Network or NACE Coatings Network. These free list servers, established in the late 1990s, continue to grow in membership and popularity. To join either or both of the networks, simply go to the NACE Web site at click on the Corrosion Central link, and then Online Corrosion Community List Servers. You will reach a subscriber page as well as access to archived questions and answers back to Following is a recent sampling from the NACE Corrosion Network on questions and answers related to protective coatings. Please be advised that the items are not peer-reviewed, and opinions and suggestions are entirely those of the inquirers and respondents. Pinholes not detected with holiday testing Q A carbon steel (CS) raw water storage tank has three coats of epoxy applied at 12 to 15 mils (300 to 375 µm). The tank is new and was field blasted with copper slag. The tank passed a low-voltage holiday test. The tank was filled for a hydrostatic test and two weeks later drained. After draining, the painted surface was covered with pinpoint rusting. At 30X magnification, they appeared to be true pinholes. The tank has stainless steel (SS) cables and a SS float to run an exterior fill level gauge. The SS seems to be in contact with the CS as it jeeps (rings, beeps) when touched with the holiday tester. After the pinholes showed themselves, the holiday detector would still not jeep. Three detectors were used with the same results. One of the manufacturers said that these low-voltage instruments are for small areas, and we should be using a high-voltage set at 900 V. Has anyone seen pinholes so small that they would not show during a holiday test? Is the small amount of SS enough to drive dissimilar metal (galvanic) corrosion on a 500,000-gal (2,300,000-L) tank? Is it possible that the copper slag could be a culprit? A The SS cables likely are contacting the tank on the floor, where they are tied off to lugs, and on the roof, inside spring-loaded connection pipes that are fabricated to keep tension on the cables. At 15 mils, you could miss holidays if a surfactant is used. I have seen surface rust resulting from copper slag. If blasting was done on the floor after the shell was completed and the dust from the floor blasting remained on the shell when the tank was filled with water, this could result in what you describe. A Provided the holiday detector was working properly, had a good ground, and a small amount of surfactant was added to the water used to wet the sponge, it should ring over and through pinholes. It seems to me that some steel dust or some other iron trace contaminate had gotten on the surface of one of the coats, but the first coat is still holding up. If the tank was uncoated, strictly from a large anode/small cathode perspective, I wouldn t think you would have a major problem with the mismatch. However, if there are small areas of coating failure, the situation may reverse itself, and could result in pitting, as the galvanic effect would not have such a large area to spread itself over. A I believe the answers to the inquirer s three questions are all no. If the pinholes are truly pinholes (i.e., through the full coating system), they would almost certainly jeep, even with low-voltage testing, particularly after the tank had been in immersion and the coating resistance was lowered by water absorption. I don t buy the try high-voltage testing theory, but we ll never know because the tank has been in service. It would be interesting to know if higher-voltage testing revealed holidays, and at what voltage on the tester. About 900 V probably is right for an epoxy system at 15 mils that recently has been in immersion service. SS will set up a bimetallic cell, but the small amount in a float and wires is unlikely to drive corrosion to such an extent that holes are blown in locations all across the surface. Typically, coating defects created in this way are not distributed evenly, since every one that s formed draws current away from other potential locations in the vicinity. These other locations remain insulated, even if marginally. Besides, once formed, defects created this way almost certainly would jeep. My favorite theory here is that there are

7 Summer 2012 InspectThis! 7 Coating in a liquid sulfur storage tank We have observed corrosion in the Q vapor space of an aboveground storage tank storing liquid sulfur. The tank was built per API 650. The diameter and height of the tank are and m, respectively. The tank is completely insulated. The tank s shell and bottom plate have low-pressure steam coils. The steam coils on the shell are m. The roof plates have external low-pressure steam coils. Liquid sulfur in the tank is typically stored at 125 to 135 C. Steel supports are welded on the top shell course along the periphery to support steam pipes and connections on the roof. Staircase structures are also welded to the shell. We suspect these structures act as heat sinks, causing temperatures to drop, condensation, and corrosion on the internal shell. Are there methods to mitigate corrosion? Would internal aluminum flame-spray metallizing be suitable in this service? Would insulating the welded structures help in reducing the corrosion rate? Would increasing the temperature of the liquid sulfur help to reduce corrosion? inclusions in the topcoat, not pinholes. Try scraping gently at some typical defect areas while observing the area through a 30X microscope. Perhaps a Tooke Gauge microscope could be used to provide some clearance while scraping. If these are really pinholes, they will be visible until the entire coating is scraped away. A Copper slag tends to produce a higher blast profile than garnet or green/black diamond, so you may want to check the profile. The rule of thumb is that the profile should be about 20% of the overall film thickness. If it exceeds this, it could lead to such end results. Also, a wet sponge holiday tester may produce better results. I have seen similar results on several occasions when the instrument used was simply out of calibration, or other related problems. Check the instrument used for calibration, etc. A Holiday testing is a simple conductivity test. If the coating is not more than 20 mils (500 µm) and bare steel spots and pinholes to the substrate are visible and still will not activate the tester, then something is wrong with the test process. If the electric current is completed, the tester will beep. Check your ground, dry film thickness, and conductivity of the test solution. You may need to add 1 oz (30 ml) of photoflow solution to the test water to improve conductivity or test with a high-voltage tester at voltages the manufacturer recommends. Make an intentional bare metal spot in the tank and check the tester on the spot. If it doesn t beep, something is wrong with the electrical connection.

8 8 InspectThis! Summer 2012 A Our tank cars carry most of the molten sulfur hauled in the United States. Insulation is used to maintain the commodity in the molten state to facilitate unloading. Linings are used in molten sulfur tank cars to prevent corrosion. Increasing the temperature of molten sulfur would increase corrosion, not reduce it. Inorganic zinc and crude benzene Q A boat s cargo tanks are coated with an inorganic zinc (IOZ) coating. The boat had been hauling crude benzene from one place to another, when suddenly the boat s owner claimed damage to his cargo tank coating. We still have to go and look at the coating, but here s what the owner claims so far: The IOZ shows white staining on and above the waterline. Supposedly, there was hydrogen sulfide (H 2 S) in the crude benzene which, in vapor phase, would have condensed, forming sulfuric acid (H 2 SO 4 ) that attacked the IOZ. An analysis of the white zinc oxidation products showed zinc sulfate (ZnSO 4 ). I can see the white staining being excessive zinc oxidation, possibly from chemical attack by some kind of cargo (not only crude benzene was hauled). However, here s what I d like your opinion on: 1) Would there be enough H 2 S in crude benzene for it to condense from vapor phase into H 2 SO 4 enough to initiate this attack? 2) IOZs have been protecting against crude benzene for up to three years for this customer without any problems. All of a sudden, one batch caused this damage. Any idea why? 3) If ZnSO 4 was formed, does anybody know how to remove this without damaging the IOZ? A I have the following comments: 1) We used to use a lot of IOZ primer for vinyl or other topcoats. I recall that they would not tolerate any kind of sulfur contamination before the topcoat. We never explored the whys or wherefores. 2) It s not easy to oxidize H 2 S all the way to sulfur trioxide (SO 3 ) and H 2 SO 4. 3) It s unreasonable to expect a guarantee of any coating s performance except in refined (or at least technical grade) organic chemicals in which the chemical resistance has been properly tested. A In the October 2000 issue of MP, there is an article that concerns coal power plants ( Coatings for Aboveground Steel in Coal Fired Plants ), but the same thought applies to your question. It discusses the problem of sulfur contamination of the relatively porous IOZ and the fact that sulfur contamination, combined with water, would create sulfur corrosion of both the zinc and the steel resulting in a contamination that will be virtually impossible to remove, and topcoating over the contaminated zinc will lead to failure. This applies to new IOZ. Aged IOZ is usually not as porous anymore; thus, the problem is not as severe because the IOZ converts to a barrier coating when zinc carbonate (ZnCO 3 ) is formed. This plugs up the pores of the fresh IOZ. We used IOZ as tanker lining coating for many years with good results. Hope this helps.!
