2PP/3PP anti-corrosion steel pipe details

China has yet to develop a the 3PP coating industry standard, 3PP anticorrosion pipeline processing generally use the German DIN30678, steel pipes and polypropylene coating standards. The 3PP coating is mainly used for anti-corrosion pipeline conveying high temperature medium, and as a higher surface temperature, the desert regions of the sunshine longer pipeline coatings, high surface temperature, according to a longer time regions Underground Water gas, oil pipeline, the more widely used.
