Roto-lining, or Polymer Lining, represents a top-tier corrosion protection technology, offering exceptional defense against a variety of aggressive substances such as crude oil, saline water, wastewater, and highly corrosive chemicals including acids, alkalis, oxidizers, solvents, and salts. This technology can be applied to carbon steel pipes, spools, flowlines, fittings, vessels, and various process equipment by forming a protective internal polymer coating or lining with a thickness ranging from 2 to 11 mm, enhanced with corrosion-resistant additives.
