DIN 2460 STEEL PIPES FOR WATER PIPELINES
(DIN2460) |
|
| Stanhlrohre fur Wasserleitungen |
Partly supersedes
DIN 2460 and DIN 2461,
May 1966 editions |
1. Scope
This Standard applies to welded and seamless types of steel pipes ready for laying, for the construction of water pipelines.
The Standard is especially designed for use in connection with pipes for drinking water pipelines.
Nonetheless, it is also applicable to the construction of other water piplines.
This Standard does not apply to pipes for installation inside vuildings.
Pipes for installation inside vuildings are standardized in DIN 2440, DIN 2441 and DIN 2442.
2. Field of application
The pipes listed in Tables 2 and 3 are designed for permissible operation Oberpressures up to the stated nominal pressure of the pipeline. There is no need to calculate the wall thickness provided that, when the steels listed in the two tables are used, the noinal pressures associated therawith are not exceded or the wall thicknesses fall below the niminal vlues.
In the case of buried pipes, the design of the pipes takes account not noly of the maximum internal pressure but also of the stresses due to the soil cover, including the live load (SLW 60 in assordance with DIN 1072):
DIN ≤ 500 0.6 m to 6 m soil cover
DIN > 500 0.6 m to 4 m soil cover.
Where pipes are laid above ground, additional stresses, such as dead weight, the distance between supports, wind loads and snow loads,must be taken into consideration, where necessary.
The possible drop in the water pressure to the absolute pressure Pabs = 2.0 bar must also be taken into account in the design of the pipes.
