由于锅炉是一套很大的装置,在制造厂内只能制造各个大的部件,大量工作需要在现场进行组装完成。现行锅炉设计施工验收标准主要依据《特种设备安全监察条例》、《蒸汽锅炉安全技术监察规程》、《工业锅炉压力容器监察规程(1998年版)》、《火电施工质量检验及评定标准(管道篇)(2002年版)和DL/T5007-1992《建设施工及验收技术规范》等文件中对焊缝无损检测的具体规定执行,通常执行的更为详细的操作及评定行业标准依据国家质检总局质检办特函(2006)144号《关于锅炉压力容器安全监察工作有关问题的意见》应为JB/T4730-2005标准。以下介绍几种常用的无损检测方法。
Because the boiler is a large unit, only large parts can be manufactured in the factory, and a large amount of work needs to be done on site. The current boiler design and construction acceptance criteria are mainly based on “Special Equipment Safety Supervision Regulations”, “Steam Boiler Safety Technology Supervision Regulations”, “Industrial Boiler Pressure Vessel Supervision Regulations (1998 Edition)”, “thermal power construction quality inspection and assessment standards (pipeline) (2002 Edition) and DL / T5007-1992 ”Construction and Acceptance Technical Specifications“ and other documents on the non-destructive testing of welds the implementation of the specific provisions of the implementation of the more commonly carried out the operation and evaluation of industry standards in accordance with AQSIQ quality inspection The special letter (2006) No. 144 ”on the boiler pressure vessel safety supervision of the views of the relevant issues" should be JB / T4730-2005 standard. The following describes several commonly used non-destructive testing methods.
