气瓶 - 不可重金属气瓶 - 规格和测试方法

[中文适用范围]： 本文件规定了焊接、钎焊或无缝结构的非再充装金属气瓶的材料、设计检验、制造工艺和工厂试验的要求。还规定了非再充装密封装置及其测试方法的要求。适用于压缩气体和液化气体用的非再充装金属气瓶。 本文件适用于满足以下条件之一的气瓶： a) 液化气体的试验压力不超过250 bar（即 p_h ≤ 250 bar），压缩气体的试验压力不超过450 bar； b) 试验压力与水容量的乘积不超过1000 bar·升（即 p_h V ≤ 1000 bar L）； c) 试验压力超过45 bar，且水容量不超过51升（即对于 p_h > 45 bar，则 V ≤ 51 升）。 [外文原描述]： This document specifies requirements for the material, design, inspections, construction and workmanship, manufacturing processes, and tests at manufacture of non-refillable metallic gas cylinders of welded, brazed, or seamless construction. This document also specifies the requirements for the non-refillable sealing devices and their methods of testing. It is applicable to non-refillable metallic gas cylinders for compressed and liquefied gases. NOTE The specific gases permitted in cylinders constructed to this document can be limited by national or international requirements. This document is applicable to cylinders where: a) the test pressure does not exceed 250 bar 1) (i.e. p h ≤ 250 bar) for liquefied gases and 450 bar for compressed gases; or b) the product of the test pressure and the water capacity does not exceed 1 000 bar·litres (i.e. p h V ≤ 1 000 bar l); or c) the test pressure exceeds 45 bar and the water capacity does not exceed 5 l (i.e. for p h > 45 bar, then V ≤ 5 l). 1) 1 bar = 0,1 MPa = 10 5 Pa; 1 MPa = 1 N/mm 2
