ISO 9330-5:2000

This part of ISO 9330 specifies the technical delivery conditions for submerged arc-welded tubes of circular crosssection, made of unalloyed or alloyed steel with specified low temperature properties. These tubes are intended for pressure purposes in cases when the material is also used as part of a low temperature piping system. The requirements of appropriate international application standards and relevant national legal regulations shall be taken into account by the user. For pressure-containing equipment International Standard ISO 5730 is available. For the general technical delivery requirements, see ISO 404. NOTE The English words "tube" and "pipe" are synonymous.
