Steel tubes and fittings for onshore and offshore pipelines - External three layer extruded polypropylene based coatings

Scope

This European Standard defines the application of factory applied external three layer extruded polypropylene based coatings for the corrosion protection of tubes and pipeline components. External extruded polypropylene coating can be used for the protection of buried or submerged tubes for service at temperatures: - Type 1: -20 °C/ +80 °C; - Type 2: -20 °C/ +110 °C. The coatings in this standard can be applied to longitudinally or spirally welded and to seamless steel tubes and components used for the construction of pipelines for conveying liquids or gases.
