Abstract:

Twisted tube has been widely used in radiation tubes of ethylene cracking furnace. By introducing several casting technologies for twisted tubes, this paper analyzes the non-destructive testing and mechanical properties of twisted tube for different casting technologies, so as to illustrate the advantages and disadvantages of different casting technologies.

Key words: twisted tube, radiation tubes of cracking furnace, casting technology
