This European standard specifies requirements for seamless steel tubes used in pressure equipment at elevated temperatures, covering non-alloy and alloy steels. The latest version (2024) includes updates to material grades, testing, and inspection procedures.
Scope
- Applies to seamless tubes for boilers, heat exchangers, and pressure vessels.
- Covers non-alloy (P195GH, P235GH, etc.) and alloy steels (16Mo3, 13CrMo4-5, etc.).
- Suitable for high-temperature service (creep-resistant steels).
