EN 10216 European standard replaces the old standard DIN 17175 and DIN 1629. This standard is designed for pipes used in pressure applications, such as pipes
• EN 10216 contains several parts.
• EN 10216 part 1: Non-alloy steel pipes, with specified characteristics at room temperature
• EN 10216 Part 2: Non-alloy steel pipes with specified characteristics at high temperatures
• EN 10216 Part 3: Fine-grained alloy steel pipes for any temperature
• EN 10216-1, QUALITY P235TR2 (DIN 1629, ST.37.0)
• P = pressure
• 235 = flow limit in N / mm2
• TR2 = quality with specific properties related to aluminum content, impact and inspection values ​​and test requirements. (Unlike TR1, for which this is not specified).
• EN 10216-2, QUALITY P235 GH (DIN 17175, ST.35.8 CL. 1, (BOILER PIPES)
• P = pressure
• 235 = flow limit in N / mm2
• GH = properties tested at higher temperatures

EN 10216-3, QUALITY P355 N (more or less equivalent to DIN 1629, ST.52.0)
• P = pressure
• 355 = flow limit in N / mm2
• N = normalized *
Normalized is defined as: normalized (hot), laminated or annealing standard (at a temperature of min 930 ° C). This applies to all steels designated by the letter N in the new European standards.
Pipes: The following standards are replaced DIN with EN

Steel grade
· EN10216-1 P195
· EN10216-1 P235
· EN10216-1 P265
The composition of this steel makes it ideal for applications where the working temperature is high or normal, and the material is used by manufacturers in the oil, gas and petrochemical industries.

EN1026 specifies the technical delivery conditions in two test categories for circular section seamless tubes, with specified high temperature properties, of non-alloy steel and alloy steel.
