一号计转站在整个施工过程中不能停产,而加热炉盘管与生产汇管在连接上直接与主要生产流程相关,且由于受到特定空间限制,无法进行带压开孔作业,使得施工无法顺利进行。通过设计优化,将原定的三通连接调整为开孔焊接,满足了施工所需时间要求。液压安全阀通常是在防火呼吸阀无法正常呼吸的情况下才工作,是对储罐的后续保护,其压力区间应比防火呼吸阀略宽,通过查阅相关规范,证明了这种理论分析的正确性。
No.1 gauge transfer station can not stop production during the whole construction process, while the heating coil and production supervisor are directly connected with the main production process, and due to the specific space constraints, it is impossible to carry out the work with pressure to open the hole and make the construction impossible Smooth progress. Through the design optimization, the original three-way connection adjusted to the hole welding, to meet the construction time required. Hydraulic safety valve is usually in the case of fire breathing valve can not work properly, is the follow-up protection of the tank, the pressure range should be slightly wider than the fire breathing valve, by consulting the relevant norms to prove that the theoretical analysis is correct Sex.
