Product Description
EN 10217-2 High Temperature Welded Pipes – Non-Alloy & Alloy Steel for Elevated Service Fire Protection Applications
What Are EN 10217-2 High Temperature Fire Sprinkler Pipes?
EN 10217-2 high temperature welded pipes are electric-resistance welded (ERW) steel tubes manufactured to the European standard EN 10217-2, specifically designed for elevated temperature service (typically up to 500°C). While not a standard fire sprinkler pipe specification for conventional wet systems, EN 10217-2 pipes are increasingly specified in special hazard fire protection scenarios where high-temperature resistance is critical — such as industrial fire pump discharge piping near heat sources, foam concentrate lines in petrochemical plants, and steam-trace jacketed fire mains in cold climates.
Unlike EN 10217-1 which focuses on room-temperature pressure applications, EN 10217-2 covers both non-alloy and alloy steels with guaranteed high-temperature yield strength and creep resistance, making it the go-to specification for boiler tubes, superheater tubes, steam lines, and heat exchanger piping in power generation, petrochemical, and industrial heating systems — many of which integrate fire suppression components.
This standard is harmonized under the EU Pressure Equipment Directive (PED 2014/68/EU) and is recognized for fire sprinkler system components operating under elevated temperature conditions.
Material & Steel Grades
EN 10217-2 includes four primary steel grades, each offering different levels of high-temperature performance suitable for fire protection and industrial piping:
| Grade | Type | Max Service Temp | Yield Strength @ 350°C (min) | Typical Use in Fire Protection |
|---|---|---|---|---|
| P195GH | Non-alloy | ~400°C | ~115 MPa | Low-pressure steam, economizers, auxiliary fire system piping |
| P235GH | Non-alloy | ~450°C | ~140 MPa | Boilers, steam drums, headers; fire pump discharge lines near heat |
| P265GH | Non-alloy | ~450°C | ~160 MPa | High-pressure boilers, thick-wall vessels; high-pressure fire mains |
| 16Mo3 | Alloy (Cr-Mo) | ~500°C | ~180 MPa | Superheaters, reheaters; special hazard fire protection near furnaces |
💡 Fire sprinkler relevance: EN 10217-2 pipes are used in industrial fire sprinkler systems where ambient temperatures exceed the normal limits of standard fire sprinkler pipe (e.g., near kilns, furnaces, steam vents). The P235GH and P265GH grades are particularly suitable for fire pump discharge piping and deluge system headers in high-temperature environments.

Applications: Where Are EN 10217-2 Fire Sprinkler Pipes Used?
EN 10217-2 high temperature welded pipes are essential in industries where fluids or gases are transported at elevated temperatures, including fire protection systems in challenging environments:
- Industrial fire sprinkler systems – Near furnaces, boilers, kilns, and steam lines
- Fire pump discharge piping – High-temperature discharge from diesel or steam-driven fire pumps
- Foam concentrate lines – In petrochemical and refinery fire protection
- Steam-trace jacketed fire mains – For freeze protection in cold climates
- Power generation – Boiler tubes, superheater tubes, reheater tubes, economizer coils (often adjacent to fire suppression zones)
- Petrochemical & refining – Steam lines, process heaters, catalytic cracker piping with integrated fire protection
- Industrial heating – District heating networks, thermal oil systems, waste heat recovery
- Chemical plants – Heat exchangers, reactors, high-temperature transfer lines with fire suppression requirements
- Marine & offshore – Exhaust gas boilers, steam systems on ships, fire main systems near engine rooms
