Application and Analysis of Coating Materials for Worldwide Pipelines Completed in 1993

The total amount of different coatings applied in the world, 1993 was up to 2085.6×10⁴m² in area. which is described in the 3rd and the 4th issues of the American Pipeline Abstract. Of all the coating materials. fussion epoxy powder takes 42% and is reffered to as the main kind folowed by coat tar enamel and polyethelyne. But the application status varies in the USA and other countries. for ehample. fussion epoxy powder is most widely used in pipelines of all diameters in USA. but mainly used in large diameter pipelines in other countries. Instead. coal tar enamel remains the most widely used, but mainly in small size pipelines. Multi-player coatings find their less use. taking 0.63% of the total amount only.
