Understanding of Specification: EN 10028-3

Introduction:

EN 10028-3 is a European standard specification for flat products made of steels for pressure purposes. It specifically covers weldable fine grain steels, normalized, designed for pressure vessels and boilers. Let's explore the details of EN 10028-3 specification, its subgrades, the significance of each element and suffix, and their end uses:

 

Subgrades:

1. P275NH, P275NL1, P275NL2: These subgrades are normalized fine grain steels with minimum yield strengths ranging from 215 MPa to 275 MPa.

 

2. P355N, P355NH, P355NL1, P355NL2:

These subgrades are normalized fine grain steels with minimum yield strengths ranging from 295 MPa to 355 MPa.

 

3. P420NH, P420NL1, P420NL2: These subgrades are normalized fine grain steels with minimum yield strengths ranging from 340 MPa to 420 MPa.

 

4. P460NH, P460NL1, P460NL2: These subgrades are normalized fine grain steels with minimum yield strengths ranging from 370 MPa to 460 MPa.

 

Elements and Suffixes:

1. P: Indicates that the steel is intended for pressure purposes.

 

2. 275, 355, 420 and 460: Denotes the minimum yield strength of the steel in megapascals (MPa). Higher numbers indicate higher strength.

 

3. N: Indicates that the steel is normalized. Normalizing involves heating the steel to a specific temperature and then cooling it in air to obtain a uniform structure, improving its mechanical properties.

 

4. NH: Denotes elevated temperature properties. The "H" stands for "High temperature," indicating that the steel is suitable for use at elevated temperatures.

 

5. NL1, NL2: Indicates low temperature properties. The "L" stands for "Low temperature," indicating that the steel has been tested for impact toughness at low temperatures.

 

End Uses:

- Pressure vessels and boilers in various industries including:

- Petrochemical

- Chemical processing

- Power generation (boilers)

- Oil and gas

- Storage tanks for liquids and gases

- Heat exchangers

- Reactors

 

Conclusion:

EN 10028-3 specification provides guidelines for manufacturing pressure vessel and boiler steel plates, ensuring they meet specified mechanical and impact properties under different temperature conditions. The subgrades and suffixes denote the steel's yield strength, treatment, and suitability for specific applications, enabling engineers and manufacturers to select appropriate materials for pressure equipment across diverse industries. Understanding these specifications is essential for ensuring the safety, reliability, and performance of pressure vessels and boilers in various operational environments.
