储罐排管式加热器损坏原因分析

ANALYSIS ON THE DAMAGE REASON OF AR- RANGED PIPE TYPE HEATER IN STORAGE TANK

立式圆筒形储罐用的排管式加热器,在分配管与管束连接处经常发生损坏。作者采用有限元法对易损部位进行了应力计算,证明该部位的强度没有问题。同时对排管式加热器的设计提出了改进意见。

The arranged pipe heater of vertical cylindrical storage oil tank often occurred damage at the joint zone between the distributor pipe and bundle . By the use of finite element method, the stress calculation of damageable zone was conducted by the author, and proved that the strength of that zone had no problem. The design improvement of arranged pipe type heater was proposed simultaneously.
