气瓶.无缝钢和无缝铝合金气瓶和管.定期检验和试验

[中文适用范围]： 本文件规定了定期检查和试验的要求，以验证将在今后一段时间内重新投入使用的气瓶和管道的完整性。本文件适用于用于运输加压压缩和液化气体、水容量为 0.5 升至 150 升的无缝钢制和无缝铝合金运输气瓶（单个或组成一捆），以及用于运输加压压缩和液化气体、水容量大于 150 升的无缝钢制和无缝铝合金运输气管（单个或组成一捆）。在切实可行的范围内，它也适用于水容量小于 0.5 升的气瓶。本文件不适用于乙炔气瓶的定期检查和维护，也不适用于复合材料气瓶的定期检查和试验。注：除非另有说明，本文件中使用的“气瓶”一词均指气瓶和管道。 [外文原描述]： This document specifies the requirements for periodic inspection and testing to verify the integrity of cylinders and tubes to be re-introduced into service for a further period of time. This document is applicable to seamless steel and seamless aluminium-alloy transportable gas cylinders (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l and to seamless steel and seamless aluminium-alloy transportable gas tubes (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity greater than 150 l. It also applies, as far as practical, to cylinders of less than 0,5 l water capacity. This document does not apply to the periodic inspection and maintenance of acetylene cylinders or to the periodic inspection and testing of composite cylinders. NOTE Unless noted by exception, the use of the word "cylinder" in this document refers to both cylinders and tubes.
