Z8002

规定取得压力容器检验员或检验师资格证。4.2.3 检查人员应做好波纹金属软管的定期检查记录，检查记录应详尽、真实、准确，现场检查完毕后应及时出具定期检查报告。5

检查前准备5.1检查机构检查前准备工作5.1.1 检查用的仪器、仪表和量具应在有效的检定或者校准期内，检查用的照明和电源应符合国家相关规定。5.1.2 波纹金属软管与耐压试验装置之间的连接应牢固、可靠。5.1.3 耐压试验用的压力表应在有效检定期内，数量不少于

2

块，精度不得低于

级，量程应为试验压力的

～2

倍，并安装在便于观察的位置。5.2 使用单位检查前准备工作5.2.1确认装卸软管的选型应符合下列要求：工作压力的

2

倍，装卸压缩气体的波纹金属软管公称压力不得小于装卸系统工作压力的

1.3倍；波纹金属软管的最小爆破压力应大于

4

倍的公称压力。——波纹金属软管的材质应与充装介质相容，冷冻液化气体介质的装卸用管能够满足低温性能要求。5.2.2 应对接触液氧等氧化性介质的波纹金属软管的内表面和接头部位进行脱脂处理和防止油脂污染措施。5.2.3 应在波纹金属软管上标志开始使用日期，确认其使用年限不得超过设计使用寿命。6

检查分类、检查项目与检查周期6.1 检查分类压力容器波纹金属软管的定期检查分为日常检查和全面检查。DB43/T

1976—6.2 检查项目6.2.1 日常检查项目包含资料审查和外观检查。6.2.2 6.3 检查周期压力容器波纹金属软管在每次使用前都应开展日常检查，每年至少开展一次全面检查。7

资料审查7.1 资料审查至少包括以下内容：——出厂资料，包括产品质量证明文件或产品合格证、使用说明书等，在首次检查时进行审查；——检查资料，包括日常检查记录、全面检查记录和报告；——使用管理资料，包括维护保养记录、异常情况处理记录等。7.2 波纹金属软管制造单位应注明软管的设计使用寿命。对使用年限超过设计使用寿命的波纹金属软管，登记后应予以报废。7.3 没有产品合格证的波纹金属软管为不合格产品，登记后应予以报废。8

外观检查8.1 波纹金属软管网套应与波纹管贴合，表面应平整光滑且网花均匀，无破损、破裂、折叠、扭曲和老化等缺陷；8.2 波纹金属软管接头或连接处密封面无裂纹、擦伤、毛刺、砂眼、焊渣等缺陷；8.3 波纹金属软管波纹管表面不应有碰伤、焊渣等缺陷。9

耐压试验9.1 试验时环境温度不得低于

5℃，当温度低于

5℃应采取防冻措施。9.2

25mg/L除干净。9.3 试验现场应有可靠的安全防护措施。9.4 将波纹金属软管充满液体，滞留的气体应排净，波纹金属软管外表面应保持干燥。9.5 当波纹金属软管壁温与液体温度接近时，缓慢升压至软管公称压力，确认无泄漏后继续升压到公称压力的

倍，保压

；然后降至公称压力，保压

30min

进行检查，检查期间压力应保持不变。9.6 保压期间不得采用连续加压来维持试验压力不变，不得带压紧固或者向受压元件施加外力。9.7 试验过程中不得进行与试验无关的工作，无关人员不得进入试验现场。9.8 进行液压试验的波纹金属软管，同时满足以下列条件为合格：——无破裂、无渗漏；——无可见的变形；DB43/T

1976—10

泄漏性试验合格后应进行泄漏性试验。泄漏性试验应符合下列要求。10.1 泄漏性试验介质应为干燥洁净的空气、氮气或者其他惰性气体。10.2 泄漏性试验时，试验时环境温度不得低于
