DIN 30670 outlines the criteria governing the application of factory-applied coatings featuring a three-layer extruded polyethylene or polyethylene-based formulation. These coatings are designed to safeguard steel pipes and components from corrosion. The DIN 30670 coating is applicable to longitudinal, DSAW (Double Submerged Arc Welded) pipes, seamless steel pipes, and fittings employed in pipeline construction to transport liquids or gases. This coating system proves effective in safeguarding steel pipes, whether buried underground or submerged in water, within a temperature range extending from -40°C to +80°C.
