EN10216-1 Seamless Steel Tubes for Pressure Purposes
Material Specification
EN10216-1 is a European standard that specifies the requirements for seamless steel tubes intended for pressure purposes. These tubes are widely used in industries such as oil and gas, petrochemical, and power generation due to their ability to withstand high pressure and temperature conditions. The standard covers several steel grades, including P195TR1 (1.0107), P195TR2 (1.0108), P235TR1 (1.0254), P235TR2 (1.0255), and P265TR1 (1.0258).
Key Features
- High Pressure Resistance: Designed to withstand high internal pressures.
- Temperature Tolerance: Suitable for high-temperature applications.
- Corrosion Resistance: Enhanced resistance to corrosive environments.
- Versatility: Applicable in various industrial sectors.
- Quality Assurance: Manufactured under strict quality control measures.
Chemical Composition
The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition for each grade:
| Element (%) | P195TR1 (1.0107) | P195TR2 (1.0108) | P235TR1 (1.0254) | P235TR2 (1.0255) | P265TR1 (1.0258) |

| Property | P195TR1 (1.0107) | P195TR2 (1.0108) | P235TR1 (1.0254) | P235TR2 (1.0255) | P265TR1 (1.0258) |
| Tensile Strength (MPa) | 320 - 440 | 320 - 440 | 360 - 500 | 360 - 500 | 410 - 570 |
| Yield Strength (MPa) | ≥ 195 | ≥ 195 | ≥ 235 | ≥ 235 | ≥ 265 |
| Elongation (%) | ≥ 25 | ≥ 25 | ≥ 25 | ≥ 25 | ≥ 22 |
Steel Grade
The steel grades covered under EN10216-1 are designed to meet specific requirements for pressure applications. Each grade offers a balance of mechanical properties and chemical composition to suit different industrial needs.
Application
EN10216-1 seamless steel tubes are used in a variety of applications, including:
- Boiler Tubes: For high-pressure steam boilers.
- Heat Exchangers: In chemical and petrochemical industries.
- Pipeline Systems: For transporting gases and liquids under pressure.
- Pressure Vessels: In power generation and industrial processing.
Possible Alternative Grades
Depending on the specific requirements of an application, alternative grades may be considered. These could include:
- ASTM A106: A comparable standard for seamless carbon steel pipes for high-temperature service.
- DIN 17175: A German standard for seamless tubes for elevated temperatures.
- API 5L: For pipeline transportation systems in the petroleum and natural gas industries.
