主要探讨了核电站辅助设施(balance of the plant，BOP)管道施工中出现的一些技术问题，如施工质量的可追溯性、共用支架防变形、电抛光管内部的洁净控制、沟槽式管件的应用等，并结合实际制订了相应的技术措施。这些措施通过现场的实际操作检验，证实了简单、有效，为后续核电BOP管道施工提供了借鉴。

The technical problems, such as the traceability of the construction quality, anti-deformation of shared support, clean control inside the electro-polished tube, and applications of groove pipes, are discussed in this paper, which occur in the pipe construction of balance of nuclear power plant. Furthermore, the corresponding technical measures are established combining with the practical condition, which are proved to be simple and effective by the on-site inspection, providing references for the pipeline construction of balance of nuclear power plant in the future.
