Archco linings and coatings are designed specifically to protect steel and concrete surfaces from aggressive environments. Denso provides a multitude of tank/pipe lining systems for differ- ent temperatures and environments to protect against corrosion for tanks, internal pipe, exchangers, knock-out drums, chime areas, bund areas, pressure valves, pressure vessels, and more. The coat- ings and linings will protect against crude oil, seawater, waste water, fuels, solvents, lubricants, and acids. In business for over 135 years, Denso is recognized as a global leader in corrosion prevention. Case History A large U.S. oil pipeline, storage, and transportation company had been experiencing numerous coating failures with their exist- ing internal tank linings and was looking for a solution. The deci- sion was made to switch to the Denso Archco 400 as a primer and Archco 476P as a topcoat, due to excellent chemical and high- temperature resistance that these linings provide. Other key factors that played into the decision to switch to Denso were the company's success with several other Denso buried pipeline coatings and the valuable technical service provided by Denso. The internal tank floor and two feet up the sidewall were blasted to a near white finish (NACE No. 2/SSPC SP-10). The Archco 400 primer, which is a two-part epoxy with superior wet-out properties suitable for sealing heavily pitted floors, was easily sprayed with a single leg (68:1) airless spray unit. The following day the Archco 476P was applied using a plural component airless spray unit. This allowed the tank to be returned to service very quickly (8 hours at 75 °F/23 °C). The Archco 476P is a 100% solids, two-part, high- temperature resistant, epoxy phenolic-novolac system designed for internal tank linings. The owners can expect a service life of 20+ years with the Denso Archco Tank & Pipe Lining Systems.
