After pipe mapping and spotchecking is completed, pipes are dried with heated, compressed air. A safe abrading agent is blown through the pipe system, removing rust and corrosion by-products that are collected in a holding unit for disposal. Compressed air is applied once again to remove fine particles.
Optimal internal pipe surface temperature is created prior to epoxy coating. Another air pressure leak test is performed. Conditioned air is then introduced into the pipe to uniformly distribute the epoxy coating throughout the pipe segment. Following the coating application, continuous controlled air flows through the piping to facilitate epoxy curing.
After the epoxy coating cures, valves and couplings are refitted. A final leak test and inspection confirms lining integrity. Water quality, volume, and flow tests confirm system functionality.
