Pipe coatings of improved performance are increasingly in demand. It has recently been estimated that over 600,000 miles of gas pipelines is in operation in the world with the mileage growing rapidly. Nearly 50,000 miles of new gas and oil pipelines is currently being laid each year over the world. In recent years, there has been a considerable increase in submarine pipelines, arising from the rapid growth in the number of offshore installations. It has long been recognized that a protective internal coating for pipe affords savings to pipeline operators. The coating provides protection against corrosion and abrasion and reduces cost of scrubbers, strainers, pigs, and other types of pipeline cleaning equipment. It greatly reduces maintenance and labor costs, provides protection for the pipe interior against accumulation of deposits, and substantially increases throughput. Specific spray and cleaning equipment is employed for internally coating small and large-diameter pipes, with appropriately formulated epoxy-type coatings, following sound surface preparation, such as abrasive blasting preferably, or acid cleaning. Advantages are outlined of internally coating pipelines carrying gas. Methods of application have been described for internally and externally coating pipes with liquid and powdered epoxy coatings.
