Anti-corrosion Coating Compound (ACC) BIURS

Anti-corrosion Coating Compound (ACC) BIURS is designed for insulating oil or gas pipelines laid above- or under-ground, tanks and vessels; for protecting joint fittings and shut-off valves, compressor pipes, delivery measuring and pumping stations. Application can be done either when the pipe is being laid or at the manufacturers.

This kind of protective coating is a compound that includes fast-setting Primer MB and protective mastic BIUR that get applied one after another onto the pre-treated pipe surface. Layers of the compound are chemically bound.
