Abstract

The ultra-high pressure polyethylene tubular reactor requires an casing heat exchanger because of the high temperature in the working process. Instead of using welding to connect the inner and outer tubes, ultra-high pressure tubular reactors are usually connected by means of the shrinking fit. The shrinking fit is essentially an interference fit connection, and the theoretical calculation uses the method of calculating the amount of interference. However, due to the high and temperature that the shrinking fit is subjected to, the theoretical calculation results have a large differences with the actual. This paper identifies the problems existing in the theoretical calculations by numerical simulations and finds out the specific differences between the actual situation and the theoretical calculations. This lays the theoretical foundation for the optimization of the shrinking fit of the ultra-high pressure tubular reactor.
