4、ording to the given parameters and technical requirements to design the corresponding tube heat exchanger. At first, this paper calculated according to the process conditions, select heat exchanger type, the design selected fixed tube plate shell and tube heat exchanger, heat exchanger parameters
5、. Then carries on the structure design and strength calculation, four kinds of working condition checking, the result is meet the requirements. Finally take over reinforcement, hydrostatic test, the result is meet the requirements. According to the standard selection of takeover, flange, saddle s
