Seamless Pipes and Tubes for Pressure Applications

Seamless Pipes and Tubes for Pressure Applications
EN 10216-1, EN 10216-2, PIPE, Seamless Pipes, Seamless tube
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
We are one of the professional China manufacturers work at EN 10216-1(EN 10216-1 steel tubing).

This part of EN10216 may also be applied for tubes of non-circular cross section; necessary modification should be agreed a time of enquiry and order.

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)

P = Pressure
235 = minimum yield strength in N/mm2
GH = tested properties at higher temperatures
