Coal Tar Enamel Coatings Prove Out In Service

摘要

Steel pipelines are among the safest and most efficient method of transport for large volumes of gas, oil and water. The drawback is steel corrodes. To protect steel pipes from exposure to a widernarray of natural enemies-including water, salts, acids, marine and land organisms, soil stresses, root growth and cathodic currents-many pipeline engineers think they need to rely on the newest technologies to meet their complex needs. When it comes to pipeline coatings, however, newer isn't always better.
