EN 10216-2 P265GH Seamless Steel Pipe
Standard: En10216
Materials: Carbon steel 195GH,P235GH, P265GH
Certification: 3.1/3.2 material certificates
EN 10216-2 P265GH seamless steel pipe is a non-alloy fine-grain steel designed for pressure equipment. The "GH" stands for "Gaseous Hydrogen," indicating its resistance to hydrogen embrittlement. It is specifically engineered for high-temperature and high-pressure applications such as boilers, pressure vessels, heat exchangers, and piping systems. It is one of the most widely used and recognized materials for pressure pipes in the European market.
Standards & Compliance
- Primary Standard: EN 10216-2 (Seamless steel tubes for pressure purposes - Part 2: Non-alloy and alloy steel tubes with specified elevated temperature properties)
- Grade: P265GH
- Directive Compliance: Fully compliant with the EU Pressure Equipment Directive (PED 2014/68/EU), suitable for Category I and above equipment.
- Certification: 3.1/3.2 material certificates endorsed by an EU Notified Body are available.

Main Application Areas and Case Studies
- Power Industry: A 660MW supercritical unit uses Φ325×40mm P265GH pipes as the main steam header, with a design pressure of 16.7MPa and an operating life of 200,000 hours.
- Petrochemical Industry: Φ219×18mm pipes in an ethylene cracking furnace have operated continuously at 380°C for five years without any problems, achieving a 100% pass rate in hydrogen-induced cracking (HIC) testing.
- Pressure Vessels: The steam drum of a German supercritical boiler is manufactured using P265GH steel plate. Long-term operation has proven its high-temperature performance stability and reduced maintenance costs by 30%.
