Diversified Technology System has been utilizing A & G Industrial Services, Inc. and the Duromar HPL-4310 coating systems for about 10 years exclusively for internal coating of all our pressure vessels utilized in the nuclear industry for use as demineralizers. DTS chose to use internally coated vessels rather stainless steel vessels due to the longer life that they provide. Stainless steel is susceptical to both MIC and intergranular corrosion that result in pin-hole developing especially in weld effected areas. In the past 10 years not one vessel failure has occurred and periodic inspections of vessels have never shown any areas of concern where any type of corrosion has occurred beneath the Duromar coatings. A & G Industrial Services quality of work has always been excellent and their quality assurance programs very helpful. When vessels have arrived at their facility with defective workmanship from other suppliers, A & G was quick to point out the deficiencies and correct them prior to the coating process. Their high voltage test procedure also assures that if a defect/void should occur it is detected and corrected immediately. They have always accommodated our every request and have been very easy to work with. DTS has used these demineralizers at the following plants:

• ANO Beaver Valley Big Rock Point
• Comanche Peak Davis-Besse Ft. Calhoun
• Humboldt Bay Maine Yankee North Anna
• Salem Seabrook Shoreham
• Turkey Point V.C Summers Wolf Creek

DTS plans to use A & G for all its future vessel coatings and would strongly recommend them to any nuclear utility for there outstanding capabilities and service. If you need any additional information or would like to discuss these coating applications please contact me.

A&G Industrial Services provided the highest quality, most cost effective solution to our plant coatings needs. They are at the top of our list of contractors to provide tank lining and nuclear service level coatings applications and maintenance. This company provided a turnkey package that covered quality control, planning, work package development and implementation. The work crew and supervision were first class, highly skilled, and accommodating to plant restrictions and requirements. Most of all they are a pleasure to work with.

I just wanted to send this ‘thank you’ to let you and your employees know that we really appreciated the efforts put forth on both the Forney and Fort Myers projects. Also, I can’t say enough about your site foreman John and his diligence and attention to detail. He did a magnificent job handling your crew as well as going the extra mile on many different fronts. In addition to John, everyone on your crew was professional and hard working. In every case, your crew was on or ahead of schedule which allowed the project to run smoothly for our utility client.

If every crew was as awesome as this one my life would be a cake walk. Your guys do not mess around. Extremely professional, very safety conscious and the housekeeping is out of this world. We really enjoyed having A&G onsite, and look forward to working with you again in the future.
