3PP anticorrosion


Product Features

It is understood that most of our large pipeline corrosion protection is 3PE coating, 3PE coating has undoubtedly become China's pipeline corrosion protection. But in recent years, because of the construction of Sultan pipeline project, people gradually realized the 3PP coating. The 3PP and 3PE coatings belong to a multi-layers coating system consisting of the underlying epoxy powder, an adhesive layer in the middle, and an outer PP jacket.


PP and PE are similar in processability, and the 3PE coating activity line can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments.


According to DIN30678 standard, 3PP coating has a life span of 30 years at 80 degree centigrade, life of 15 years at 90 degree centigrade and life of 8 years at 100 degree centigrade. But the 3PE coating will soften when the temperature is higher  than 80 degree centigrade. And under the action of soil stress, some gravel will inevitably trap in the coating, or even penetrate the coating, thus destroying the anticorrosion layer. Therefore, it is difficult to guarantee the operating life of the pipeline.


The advantages of 3PP coating properties make it is possible to play an important role in the field which the 3PE coating is unsuitable. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
