Seamless Pipes And Tubes For Pressure Applications - China

Seamless Pipes and Tubes for Pressure Applications, Seamless Pipes for

Pressure Applications, Seamless tubes for Pressure Applications

The EN 10216 Euronorm replaces the old DIN 17175 and DIN 1629standards.

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

Some examples:

EN 10216-1, QUALITY P235TR2 (FORMERLY DIN 1629, ST.

37.0)

P = Pressure

235 = minimum yield strength in N/mm2

TR2 = quality with specified properties relating to aluminum content, impact values and inspection and test requirements.

(In contrast to TR1, for which this is not specified).

EN 10216-2, QUALITY P235 GH (FORMERLY DIN 17175, ST.

35.8 CL.

1, BOILER PIPE)

GH = tested properties at higher temperatures

EN 10216-3, QUALITY P355 N (MORE OR LESS EQUIVALENT TO DIN 1629, ST.

52.0)

355 = minimum yield strength in N/mm2

N = normalized*

* Normalized is defined as: normalized (warm) rolled or standard annealing (at a min temperature of 930°C).

This applies to allqualities designated by the letter ‘N’ in the new Euro Standards.
