ISO 21809-3:2016 specifies requirements for field joint coating of seamless or welded steel pipes for buried and submerged sections of pipeline transportation systems used in the petroleum, petrochemical and natural gas industries as defined in ISO 13623. This part of ISO 21809 specifies the qualification, application and testing of the corrosion protection coatings applied to steel surfaces left bare after the joining of pipes and fittings (components) by welding.
ISO 21809-3:2016 defines and codifies in Table 1 the different types of field joint coatings for pipelines.
ISO 21809-3:2016 does not address requirements for additional mechanical protection, for thermal insulation or for joint infills of concrete weight-coated pipes.
NOTE          Field joints of pipes and fittings coated in accordance with this part of ISO 21809 are considered suitable for further protection by means of cathodic protection.

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 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 chemical 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 requirements 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 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 temporary 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 standards when available, dealing with the influence of materials on water quality.

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.

-   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 coated with bitumen based enamel may be further protected by means of cathodic protection.

This European Standard specifies requirements for cement mortar linings for protecting the internal surface of steel tubes and pipeline components. It also specifies requirements for their application. It is applicable to the linings of tubes that have been welded longitudinally or spirally, seamless tubes and non-alloy steel components used for fluid transportation. This European Standard does not cover in situ applied or rehabilitation linings.
This type of lining is used in particular in the transport and distribution, under pressure or by gravity, of water intended for human consumption and industrial use, and also in fire extinguishing and waste water systems. The temperature of the water transported should not exceed 50 °C. Higher working temperature can be used by agreement of the parties.
The constituent materials of cement mortar lining, when used under the conditions for which they are designed, in permanent or temporary contact with water intended for human consumption, shall not change the quality of that water to such an extent that it fails to comply with the requirements of European regulations. For this purpose, reference shall be made to the relevant national standards transposing EN standards when available, dealing with the influence of materials on water quality.

The purpose of this standard is to define the internal and/or external coatings of polyamide powders applied by dipping in a fluidised bed or by spraying, or by roto-coating. These coatings are intended for protecting the outer and inner surface of steel tubes and their fittings (components) used as pipeline component parts. This standard may be applied for accessories (such as valves, pumps, screens, etc ... ).
This type of coating is used for the protection of buried, submerged or above ground pipelines conveying fluids at working temperatures between 0 °C and + 60 °C. Other working service temperature may be used after agreement between the purchaser and the coater.
The coatings covered by this standard are applicable to longitudinally or spirally welded steel tubes and to seamless steel tubes and their fittings components used for the construction of pipelines conveying liquids.
The internal coating of tubes to be used for the transportation of water intended for human consumption shall not affect the quality of that water to such an extent that it fails to comply with the requirements of the EU and EFTA regulations.
For this purpose, reference shall be made to the relevant national regulations and standards, transposing EN standards when available, dealing with the influence of materials on water quality and to the requirements for coatings.
NOTE   An European Acceptance Scheme (EAS) is in course of development in relation to the CPD and the DWD. Its requirements will be introduced in this standard when completed.
