This European Standard specifies requirements for the application of factory applied external bitumen based hot applied coatings for the corrosion protection of steel tubes and fittings for onshore and offshore pipelines.
This specification covers the use of bitumen based enamel when the design temperature of the pipeline is within the following limits:
- oxidized bitumen - 15 °C to + 75 °C;
- modified bitumen - 30 °C to + 90 °C.
The coatings described in this European Standard can be applied to longitudinally or spirally welded tubes or to seamless tubes and fittings used for the construction of pipelines for the conveyance of liquids or gases.
