EN 10224 Steel pipes for transporting water (including drinking water)

The European standard EN 10224 is a standard specifically designed for steel pipes, fittings, and accessories used for transporting water, including drinking water. This standard specifies the materials, dimensions, performance requirements, and testing methods for these products to ensure their safety and reliability when transporting water. The following is a detailed interpretation of the standard:

1. Scope of application

The EN 10224 standard applies to steel pipes, joints, and fittings used for transporting water (including drinking water). These products are typically used in municipal water supply systems, building drainage systems, and other occasions where water needs to be transported.

2. Material requirements

-Steel pipe: The material requirements for steel pipes are specified in the standard, usually using carbon steel or stainless steel. The material needs to have good corrosion resistance to prevent pollution to water quality during long-term use.

-Joints and fittings: The materials of joints and fittings also need to meet standard requirements, usually using materials that are the same or compatible with steel pipes to ensure the sealing and durability of the connection.

3. Dimensions and specifications

-The standard specifies in detail the size range of steel pipes, joints, and fittings, including parameters such as nominal diameter (DN) and wall thickness. For example, common specifications include DN15, DN20, DN25, etc.

-For joints and accessories, the standard also specifies their connection methods, such as threaded connections, socket welding connections, etc.

4. Performance requirements

-Pressure resistance: Steel pipes and joints need to have a certain degree of pressure resistance to withstand changes in water pressure.

-Sealing: The connection between joints and accessories should have good sealing to prevent water leakage.

-Corrosion resistance: As drinking water is being transported, the material needs to have good corrosion resistance to avoid polluting the water quality.

5. Testing methods

-Pressure testing: Steel pipes and joints need to undergo pressure testing to evaluate their pressure resistance performance in actual use.

-Sealing test: The joints and accessories must pass the sealing test to ensure that there is no leakage at the connection.

-Material testing: The material needs to undergo chemical composition analysis and mechanical performance testing to meet the standard requirements.

6. Application Fields

The steel pipes, joints, and fittings of EN 10224 standard are widely used in the following fields:

-Municipal water supply system: used for the construction of urban water supply pipelines.

-Building water supply and drainage system: used for the internal water supply and drainage system of buildings.

-Industrial water system: a water transportation system used in the industrial field.

7. Comparison with other standards

Compared with other similar standards such as EN 10241, the EN 10224 standard focuses more on steel pipes and fittings for transporting water, especially in the application of drinking water. EN 10241 is more widely applicable to various pipeline connections, including but not limited to situations where water is transported.

summarize

The EN 10224 standard provides comprehensive technical specifications for steel pipes, joints, and fittings used for transporting water (including drinking water), achieving high standards in safety, reliability, and durability. This standard has a wide range of applications in the fields of municipal water supply, building water supply and drainage, and industrial water use.
