Moving Forward In Damage-resistant Coating Technology
Today, the use of a durable external coating system in combination with cathodic protection is well-accepted as the most effective means of corrosion prevention for oil and gas pipelines. Many factors go into the coating selection decision including cost, damage resistance, pipeline terrain, backfill, soil conditions, joint coating solutions, quality assurance, logistics, electrical-resistance stability, non-shielding – CP, pipeline operating temperature, stress-corrosion cracking, and lifetime cost among others. This article will review some of the most common coating solutions used in the market today to provide resistance to damage during transportation and installation
