External anti-corrosion coatings play a crucial role in protecting pipeline pipes from corrosion and extending their service life. In this blog post, we will discuss the requirements for the 3LPE (Three-Layer Polyethylene) external coating applied to pipeline pipes. These requirements ensure the effectiveness and durability of the anti-corrosion coating.
General Specifications:
The external 3LPE coating is applied in accordance with DIN 30670-2012 standards. The anti-corrosion coating is typically black in color, and the minimum thickness of the external coating should be ≥2.5mm. It is essential for the coating to have continuity without any areas of leakage.
Testing Methods And Inspection Rules:
The following table outlines the testing methods and inspection rules for evaluating the quality of the external anti-corrosion coating:
