Research on Design,Manufacturing and Inspection of Large-diameter Multi- wave Nuclear Expansion Joint

The effect of high temperature of a nuclear power plant expansion joint for corrugated metal reactor internals gas cooled reactor was studied,which is a flexible compensation device for connecting with the pipeline system engineering in nuclear power plant construction and compensating the size variation between the cause of expansion and contraction of the reactor internals such as metal,ceramic reactor internals and reactor pressure vessel. The keys of design,manufacturing and inspection of large-diameter multi-wave nuclear expansion joint were introduced. It provided inspection section for the production of similar products of metal bellows expansion of nuclear power.
