Two model surfactant corrosion inhibitors, cetyltrimethylammonium chloride (CTAC) and cetylpyridinium chloride (CPC) were chemically modified to drag reducing agents by exchange of the chloride with salicylate counterion. The modified surfactants (cation exchanged) and the corresponding halides were compared in a corrosion test under conditions were drag reduction occurred. Drag reduction promoted corrosion inhibition in standard corrosion test.
