Abrasive blasting is often a dusty process. When contractors are required to blast near highly sensitive equipment or in areas where air quality is very important, they often need to sacrifice superior surface prep methods or erect extreme containment. At NASA’s Kennedy Space Center in Cape Canaveral, Florida one contractor was tasked with this difficult challenge - providing the highest quality surface prep and low dust blasting with Sponge Media.
When rust, corrosion and coating system failure became apparent on pipes in the filter galleries of the Lafayette Utilities Systems (LUS) water treatment plant, a rehabilitation plan was developed. One of the most important aspects of this plan was to prepare the carbon steel surfaces and create the proper anchor profile for the new coating system. Depending on the severity of the rust and corrosion on various pipe sections, the specifications called for either near white metal blast cleaning or commercial blast cleaning.
