The EN 10216 Euronorm replaces the old DIN 17175 and 1629 standards. This standard is designed for pipes used in pressure applications, such as a pipeline. This is why the associated steel qualities are designated by the letter P for ‘Pressure’. The value that follows this letter designates the minimum yield strength. The subsequent letter designations provide additional information. The EN 10216 comprises several parts. The parts that are relevant to us are as follows:

• EN 10216 Part 1: non-alloy pipes with specified properties at room temperature
• EN 10216 Part 2: non-alloy pipes with specified properties at higher temperatures
• EN 10216 Part 3: alloy pipes made from fine-grained steel for any temperature
• EN 10216 Part 4: Non-alloy and alloy steel tubes with specified low temperature
