波纹管膨胀节在催化裂化装置中是必不可少的,也是容易发生失效的零配件。通过对波纹管胀节材质的选择、结构的改进,可防止和减少波纹管膨胀节失效的发生,有助于催化裂化装置的长周期运行。
Bellows expansion joints in the catalytic cracking unit is essential, but also prone to failure of spare parts. Through the selection of the bellows expansion material, the improvement of the structure can prevent and reduce the occurrence of failure of the bellows expansion joint and contribute to the long period operation of the catalytic cracking unit.
