标准范围

ISO 21012:2018规定了用于在以下操作条件范围内输送低温流体的非绝缘低温软管的设计、结构、型式和生产试验以及标记要求:-工作温度:从？270°C到+65°C；-公称尺寸（DN）:从10到100。用于安装任何联轴器的端部配件均在本文件范围内，但联轴器应符合其他标准。ISO 21012:2018旨在设计和测试软管，以满足普遍接受的额定压力i。e、 至少公关40分。然后，可以选择PR等于或大于所用设备最大允许压力（PS）的软管。

ISO 21012:2018 specifies design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions:- working temperature: from？270 °C to +65 °C;- nominal size (DN): from 10 to 100.End fittings for mounting of any couplings are within the scope of this document, but the couplings are subject to other standards.ISO 21012:2018 is intended that the hose be designed and tested to satisfy the generally accepted rated pressure i.e. at least PR 40. Hoses may be then selected with a PR equal to or greater than the maximum allowable pressure (PS) of the equipment to which it is to be used.
