压力用途的焊接钢管 交货技术条件 第5部分:规定低温性能的埋弧焊接非合金钢管和合金钢管

[中文适用范围]： ISO 9330 的本部分规定了由具有指定低温性能的非合金钢或合金钢制成的圆形截面埋弧焊管的技术交货条件。 当材料也用作低温管道系统的一部分时，这些管可用于压力目的。 用户应考虑适当的国际应用标准和相关国家法律法规的要求。 对于承压设备，可采用国际标准 ISO 5730。 有关一般技术交付要求，请参见 ISO 404。 注：英语单词“lube”和“pipe”是同义词。 [外文原描述]： 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.
