This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 20
18、06, and conflicting national standards shall be withdrawn at the latest by May 2006. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Es

EN 10300:2005 (E) 4 1 Scope This European Standard specifies requirements for the
20、 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 limit
21、s: 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. NOTE Tubes
22、coated with bitumen based enamel may be further protected by means of cathodic protection. 2 Normative references The following referenced documents are indispensable for the application of this document.
