EN 10300:2005 (E) 4 1 Scope 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 pip
20、elines. 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 spirall
21、y welded tubes or to seamless tubes and fittings used for the construction of pipelines for the conveyance of liquids or gases. NOTE Tubes coated with bitumen based enamel may be further protected by means of cathodic protection. 2 Normative references The following referenced documents are indispen

36、patible with the chosen enamel coating; enamel comprising a bitumen based material containing a filler; reinforcing glass fabric inner-wraps as required by the category and thickness of the coating enamel; glass or composite fabric outer-wraps as required by the category of coating enamel; solar pro
37、tection, i.e. weather resistant material to protect the coating from sunlight. NOTE In special cases (for example, for onshore use, due to the nature of backfill material, or for offshore use) additional mechanical protection or a concrete weight coating may be applied by agreement. The type and gra
38、de of outer-wrap may be influenced by the presence or absence of the additional mechanical protection. 4.2 Constituent materials 4.2.1 General All constituent materials shall be supplied with the following identification: - name of manufacturer; - date of manufacture; - batch number/letter(s); - ref
39、erence to this European Standard; - type and grade of material; - expiry date (where applicable). 4.2.2 Primers 4.2.2.1 General Any primer without the required identification shall be rejected and replaced with approved material. The primer shall be supplied in suitable airtight containers. The prim
40、er shall be compatible with the chosen bitumen based enamel coating. EN 10300:2005 (E) 7 4.2.2.2 Primer Type 1 Primer Type 1 for cold application shall consist of chlorinated rubber and plasticizer and, when required, colouring matter, together with solvents needed to give a consistency suitable for

45、stant to attack by the medium to which it will normally be exposed. It shall be physically and chemically stable at the maximum application temperature of the coating material. NOTE Powdered slate and talc are typical examples of suitable filler types. The filler grading shall meet the following req
46、uirements: passing 90 m: not less than 93 % by mass; passing 250 m: not less than 99 % by mass; when tested using the wet sieving method in accordance with 7.3 of ISO 2591-1:1988. 4.2.4 Bitumen based coating enamels NOTE 1 Bitumen based coating materials are classified into two categories: Category
47、1: oxidized bitumen enamel containing filler; Category 2: modified bitumen enamel containing filler.
