Title: Painting equipment hot as 400/sup 0/F minimizes turnaround times in Amoco's Whiting refinery

Abstract

Painting high temperature equipment in Amoco Oil's Whiting, Indiana refinery posed problems for engineers and painting crews because turnaround times must be kept to a minimum. Conventional heat-resistant paints can be applied only when the equipment is shut down and has cooled to ambient temperatures. Surface preparation by sandblasting to acheive maximum coating performance interferes with the work of other trades, and may not be feasible during a tight turnaround schedule. The Whiting refinery began using a series of chemical- and heat-resistant coatings, which are specifically designed for application to surfaces as hot as 400/sup 0/F. The self-priming coatings are based on a copolymerized silicon resin and contain a high level of corrosion inhibitive pigment and a heat-actuated catalyst. Heat radiating from a hot substrate triggers the catalyst, and the coating forms a pinhole- and blister-free film that resists creeping under-film corrosion and chemical attack. The coating will air-dry when applied to cold surfaces and then produce a ''baked-on'' finish as the equipment resumes operation and passes through the curing temperature range of 225-300/sup 0/F. The Whiting refinery has substantially reduced turnaround times by using coatings that can be applied to high temperature equipment while in service, and cure on-sitemore » to a heat- and chemical-resistant finish. Sandblasting or other forms of surface preparation do not have to be scheduled when downtime is critical. Equipment can be painted at any time of the year, which allows painting contractors to smooth out work schedules to include the slack season.« less
