Point Corrosion Coal Mill

The Evolution of Pipeline Coatings [Gas

· Nearly 80 years have gone by since the first rudimentary coating systems utilizing coal tar and asphalt were applied to underground pipelines to control corrosion As time passed the pipeline coating industry has matured to the point where reliable coating materials are now available that can be applied at high production rates in a coating mill with an equally high level of quality control
