EN 10216-1 is a European standard that specifies the technical delivery conditions for seamless steel tubes for pressure purposes. It covers tubes for both room temperature and elevated temperature applications. Here are some key features of EN 10216-1 seamless tubes:
- Materials: EN 10216-1 tubes are made from non-alloy and alloy steel grades. These steel grades include P195TR1, P195TR2, P235TR1, P235TR2, P265TR1, P265TR2, 16Mo3, 13CrMo4-5, 10CrMo9-10, 25CrMo4, and others. The selection of the appropriate material depends on the intended application and the specific requirements of the project.
- Size range: EN 10216-1 tubes are available in a wide range of sizes, with outer diameters ranging from 21.3mm to 711mm and wall thicknesses ranging from 2mm to 100mm. This allows for flexibility in design and ensures compatibility with various piping systems.
- Pressure purposes: These tubes are primarily intended for use in pressure equipment and installations, such as boilers, pipelines, and pressure vessels. They are designed to withstand high pressure and temperature conditions without deformation or failure.
- Seamless manufacturing: EN 10216-1 tubes are manufactured using hot-finished or cold-drawn processes, depending on the steel grade and application. The seamless production process ensures a uniform and consistent product with excellent mechanical properties.
- Heat treatment: Depending on the steel grade and application, the tubes may undergo various types of heat treatment processes, such as normalization, quenching, and tempering. Heat treatment can enhance the mechanical properties of the tubes, making them suitable for specific applications and environments.
- Chemical composition and mechanical properties: EN 10216-1 specifies the chemical composition and mechanical properties of the steel grades used for the manufacturing of seamless steel tubes. These properties ensure that the tubes meet the required performance criteria, such as tensile strength, yield strength, elongation, and impact toughness.
- Non-destructive testing: EN 10216-1 requires manufacturers to perform non-destructive testing on the seamless steel tubes to ensure their quality and integrity. This may include tests such as ultrasonic testing, eddy current testing, or visual inspection.
- Marking and identification: EN 10216-1 specifies the requirements for marking and identification of seamless steel tubes. This includes the manufacturer’s logo, product identification, steel grade, size, and other relevant information.
