螺纹锁紧环式双壳程换热器的结构设计

STUCTURE DESIGN OF THREAD-LOCKING RING TYPE DOUBLE SHELL SIDE HEAT EXCHANGER

螺纹锁紧环式双壳程换热器 ,由于其独特的螺纹锁紧环式密封和双壳程结构 ,使之成为加氢裂化装置中的重要设备之一。与传统的法兰、螺栓连接的单壳程换热器相比 ,前者具有换热效率高、密封可靠、拆装方便、金属耗量少。

The thread-locking ring type double shell side heat exchanger is one of the key equipments in hydrocrack ing unit,because of the special thread-l ocking type seal and double shell side s tructure.As compared with traditional wi th single shell side hrat exchanger join ted with flanges bolts,the former has th e advantages high heat transfer efficien cy,reliable seal,less metal consumption and less leakage points etc.
