Pipe coating: proper preparation pays dividends
While all who coat line pipe for corrosion control know prior preparation of
the bare steel surface is important, what often is not understood is how much
a poorly decontaminated surface can affect coating performance.
Surface preparation involves more than removing rust and dirt. Contaminants,
visible and invisible, can affect coating performance.
Soluble salts, for example, can significantly shorten a coating’s useful
life.
