EN 10216 is the core standard system for seamless steel pipes used in pressure equipment, developed by the European Committee for Standardization (CEN). This standard is mandatory for EU member states and EFTA countries (such as Switzerland, Norway, etc.), covering safety requirements for critical equipment including pressure vessels, boilers, and high-temperature pipelines. Its technical provisions must comply with the European Union's Pressure Equipment Directive (PED 2014/68/EU) and carry legal binding force.

EN 10216-1: Non-Alloy Steel Pipes for Room-Temperature Performance
Grade System: P + Yield Strength + TR Grade (e.g., P235TR2)
TR1: Basic requirements (no impact test / no Al content specification).
TR2: Mandatory impact toughness + aluminum deoxidation process.
Typical Applications: Boiler water tubes, low-pressure heat exchangers (design temperature ≤120°C).
EN 10216-2: Alloy/Non-Alloy Steel Pipes for High-Temperature Performance (User-Specified Section)
Key Requirements:
High-Temperature Strength: ≥100,000-hour creep rupture data provided (Appendix A).
Grade Classification:
Non-Alloy Steel: PxxxGH (e.g., P265GH, C ≤ 0.20%).
Alloy Steel: Element-based naming (e.g., 10CrMo9-10, with Cr 2.0–2.5%).
Heat Treatment: Normalized (N) or Quenched & Tempered (QT).
Applications: Boiler superheaters (≤600°C), high-temperature reaction pipelines.
