Description / Abstract:

This part of IS0 9329 specifies the technical delivery conditions for seamless tubes of circular cross-section, made of unalloyed and alloyed steel with specified elevated temperature properties.

These tubes are intended for pressure purposes in cases when the material is also subjected to elevated temperatures, e.g. for the construction of steam generating equipment and for interconnecting pipework.

The requirements of appropriate international application standards and relevant national legal regulations shall be taken into account by the user. For boilers and pressure vessels, ISO/R 831 and IS0 5730 are available.

The following parts of IS0 9329 are now available or are being prepared:

— Part 7: Unalloyed steels with specified room temperature properties (partial revison of IS0 2604-2:1975).

— Part 3: Unalloyed and alloyed steels with specified low temperature properties (partial revision of IS0 2604-2:1975).

— Part 4: Austenitic stainless steels (partial revision of IS0 2604-211975).


1 The English words "tube" and "pipe" are synonymous.

2 This part of IS0 9329 can also be used as a basis for the manufacture of tubes of noncircular section. In this case, the values quoted in this part of IS0 9329 for chemical analysis and mechanical properties are applicable, all other requirements are by agreement between the purchaser and the manufacturer.

For the general technical delivery requirements, see ISO 404.
