EN 10208-2 is a technical delivery standard for steel pipes used for the transportation of flammable liquids or gases, applicable to steel pipes with a requirement grade of B. This standard specifies the technical requirements for welded steel pipes made of non alloy steel and alloy steel (excluding stainless steel), with a focus on material properties, inspection methods, and manufacturing processes, as well as the safety and reliability of steel pipes in the transportation of flammable fluids.
Technical requirements and level classification
This standard classifies steel pipes into different grades, with B-grade pipes having stricter requirements in terms of chemical composition, mechanical properties (such as tensile strength and impact toughness), and non-destructive testing (such as ultrasonic and radiographic testing). For example, B-class pipes need to meet specific Charpy impact energy indicators to prevent brittle fracture, and the weld coefficient can be set to 1.0. In the hydrostatic pressure test, it is allowed to calculate the test pressure using the specified wall thickness according to the protocol.
Application Fields and Material Selection
This standard is mainly applicable to pipelines transporting flammable fluids such as oil and natural gas, especially for wet or two-phase fluid environments.
