DIN 1615 Welded Circular Unalloyed Steel Tubes not Subject to Special Equipment

DIN 1615 Welded Circular Unalloyed Steel Tubes not Subject to Special Equipment

1. Field of Application
1.1 This standard applies to welded circular tubes and pipes made of St33 unalloyed steel and with the mechanical properties specified in table 1. These tubes are not designed to withstand internal pressure stresses. Bending, flanging of tubes and similar forming processs, and welding are only possible to a limited extent.
1.2 This standard does not apply to
- Welded circular unalloyed steel tubes subject to special requirements (see DIN 1626)
- High-performance welded circular unalloyed steel tubes (see DIN 1628)
- Welded circular steel tubes for structural steelwork (see DIN 17120)

2. Designation and ordering
2.1 The standard designation for tubes complying with this standard shall give in the following order;
- The term "tube";
- DIN number of dimensional standard (DIN 2458);
- Characteristic dimensions of tube (outside diameter x wall thickness);
- Number of DIN Standard giving the technical delivery conditions (DIN 1615);
- Symbol or material number of the steel grade (see table 1)
Example:
A welded tube confirming to this standard, with an outside diameter of 168.3mm and a wall thickness of 4mm as specified in DIN 2458, made from St33 steel (material number 1.0035) shall be designated as follows:
Tube DIN 2458 - 168.3 X 4
DIN 1615 - St33
or
Tube DIN 2458 - 168.3 X 4
DIN 1615 - 1.0035

3. The Chemical Composition and Mechanical Properties in details, please check DIN 1615.
4. The tolerance on dimension in details, please check DIN 1615.
