20% by volume. A filled coal-tar pitch has a higher softening temperature than the unfilled material, which results in a reduced tendency to flow. This fact is important in tropical countries or if a pipe is to operate at a somewhat elevated temperature. Resistance to impact and abrasion of a coating is improved by the filler. The viscosityWhat can I use to protect my pipeline from corrosion?What can I use to protect my pipeline from corrosion?Using coatings are one of the easiest ways to protect your pipes against corrosion. Coatings and linings can be used on pipes that are above or underground. They frequently are used in combination with cathodic protection. Some materials that are used to add defense to your pipelines include epoxy and zinc.5 Pipeline Corrosion Protection Methods You Must KnowPIPE LINES EXTERNAL CORROSIONcoatings to the pipes or employ other methods of corrosion prevention.
