- 摘要:
- 在正常运行着的液化石油气罐区内建设新球罐，必然由于大规模的动火作业，给罐区的生产安全造成极大的威胁。本文介绍先在罐区防火安全距离外进行球罐的组对、焊接和退火等作业，然后在不需用大型吊装运输设备的条件下把球罐整体搬运到罐区基础上就位找正的方法，并报道了实际应用情况。
To construct new spherical tanks in LNG tank area in normal service inevitably involves large amount of fire works which threaten the safty of tank area. This paper introduces new technique to construct spherical tanks in which the tank is first assembled, welded and annealed beyond the safe distance for fireproofing within the tank area, and then the tank is integrally transported to the tank foundation and making position correction without using large hoisting and transportation equipments.It also reports on the practical applications of this technique.1996,3(3): 27-31 收稿日期：1995-11-6分类号：TE972参考文献：
