EN 10217-2 HFW Steel Pipes
- Commodity name： EN 10217-2 HFW Steel Pipes
EN 10217-2 focuses on Electric welded non‑alloy and alloy steel tubes with specified elevated temperature properties, with P195GH/P235GH/P265GH/16Mo3 as the core steel grades. It meets different safety requirements through TC1/TC2 classification and is the core European standard for selecting high-temperature pipelines in power plants, chemical, and boiler industries. It complements EN 10216-2 (seamless steel pipes) and covers the high-temperature pressure requirements of welded processes.

About EN 10217-2
- P stands for Pressure, GH stands for High Temperature, and these are special suffixes for the EN series of high-temperature pressure-resistant steel grades, distinguishing them from normal temperature pressure-resistant steel grades (TR suffix).
- In 16Mo3, "16" represents a carbon content of approximately 0.16%, and "Mo3" represents a molybdenum content of approximately 0.3%, which is a typical naming convention for low-alloy high-temperature steel.
- TC1 and TC2: TC1 has no mandatory impact requirement and is suitable for general operating conditions; TC2 must meet an impact energy of ≥27J at 0°C, making it suitable for low-temperature or high-safety requirement scenarios.

Applicant Field:
- P195GH: Low-pressure, high-temperature pipelines (such as HVAC hot water pipes and small boiler auxiliary pipes), suitable for basic pressure scenarios at low pressure and from normal to medium temperatures, cost-effective and highly versatile.
- P235GH: The main piping of boilers, pressure vessels, and heat exchangers, it is the primary steel grade for medium-low pressure and high-temperature conditions, suitable for conventional pressure-bearing equipment in industries such as power plants, chemical, and pharmaceutical.
- P265GH: Medium to high pressure high-temperature pipelines (such as industrial boiler superheaters and steam pipelines), with higher strength, suitable for harsh conditions with high pressure and high temperature, commonly used in large power plants and industrial heating systems.
- 16Mo3: Under high temperature and high pressure conditions (such as main steam pipelines in power plants and high-temperature pipelines in refineries), the molybdenum element enhances high-temperature strength and creep resistance, making it suitable for long-term high-temperature pressurized scenarios above 500°C.
Tolerance:
- Pipe lengths: Pipes with precise lengths are manufactured with the following tolerance values: For D406,4- for pipes 0- 6m -0/+25%- for pipes 6-12m -0/+50%- for pipes longer than 12m -0/to be negotiated.
- Tightness: Pipes should be subject to water testing (7Mpa) or electromagnetic testing..
- Straightness: < 0,0015 of pipe length (below 3mm per every meter of pipe length).
- Mandatory tests:
TC1 – Ladle analysis, tensile testing, flattening test, resilience testing, tightness testing, dimension verification, visual inspection, NDT of the weld, material identification for 16Mo3 steel
TC2 - Ladle analysis, tensile testing, flattening test, resilience testing, tightness testing, dimension verification, visual inspection, NDT of the weld, NDT of the pipe body, material identification for 16Mo3 steel - Optional tests: Final product analysis, tensile testing in elevated temperature, tensile testing of the weld in room temperature, resilience testing, longitudinal resilience testing, wall thickness measurement at a distance from pipe ends, NDT in order to identify longitudinal discontinuity and delamination.
