17456-85 GENERAL
PUROSE SEAMLESS CIRCULAR STAINLESS STEEL TUBES
|
Nahtlose kreisformige Rohre aus unlegierten Stahlen fur besonders hohe Anforderungen technische Lieferbedingungen |
This standard,
together with DIN 17440 DIN 17441, DIN 17457 and DIN 1745 (July 1985 editions) supersedes DIN 17440, December 1972 edition |
The subclauses marked with
a single dot give specifications which are to be agreed upon at the
time of ordering.
The subclauses marked with a two dots give specifications which optional
and may be agreed upon at the time of ordering.
1. Field of application
1.1 This standard applies to general purpose seamless circular tubes and pipes (hereinaiter briefly referred to as tubes) made from the stainless steels listed in table 1. They are used. for example as construction tubing, a pipes for the fodd. pharmaceutical and automobile inoustries. and as pipes for domestic installation nd for decorative purposes.
Tubes conformming to ilre lequirernents o this stardard are intanded to be used on the basic of an 80% utilization of the permissble design stress in weld.
1.2 This standard does not apply to general purpose welded circular austenitic stainless steel tubes subject to special requiremnets (see DIN 17458).
