For steel tubes complying with this standard, adequate corrosion protection in the weld zone is not ensured and infiltration of liquid is to be expected. Therefore, such tubes are not used for th

5、e transport and distribution of water intended for human consumption. Because the lining materials used are subjected to additional hygiene requirements, the possibilities of subsequently lining the tubes in the weld zone are limited, especially for tubes with small diameters. Curing epoxy resin as

This European Standard shall be given the status of a national standard, either by publication of an identi

17、cal text or by endorsement, at the latest by August 2007, and conflicting national standards shall be withdrawn at the latest by August 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standa

19、339:2007 (E) 4 1 Scope This European Standard specifies the requirements for the application of liquid applied epoxy internal linings, for the corrosion protection of steel tubes. This type of lining is generally used in the transport and distribution, under pressure or by gravity, of water intended

20、 for human consumption and industrial use, sea water, waste water and also in fire water. The temperature of the water transported generally does not exceed 50 C. The choice of the lining and its limits of use depend on the type of product used, the pipe laying conditions, the temperature and the ch

21、emical composition of the fluid. The choice of the product for the medium to be transported and its qualification are not part of this European Standard. The lining consists normally of one layer of liquid product, applied by spray airless technique after surface preparation. All or some of the requ

22、irements of this European Standard can apply to the internal linings of fittings, if agreed by the purchaser and the coater. The lining in this European Standard can be applied to longitudinally or spirally welded tubes and to seamless steel tubes used for the construction of pipelines for conveying

23、 liquids. These tubes are not intended to be bent after the epoxy lining has been applied. This European Standard does not cover in-situ applied or rehabilitation linings. The constituent materials of epoxy linings, when used under the conditions for which they are designed, in permanent or temporar

24、y contact with water intended for human consumption, should not change the quality of that water to such an extent that it fails to comply with the requirements of European regulations at the end user. For this purpose, reference should be made to the relevant national standards transposing EN stand

25、ards when available, dealing with the influence of materials on water quality. 2 Normative references The following referenced documents are indispensable for the application of this document.
