개소미하형480kt／a뇨소장치고압갑안세조기관정방폭판련접방식개조，방폭판채용“정체식＋라전긴고”방식，기우점：불재채용한접형식、감소방폭판탁장시공보취、절성검수시공시간화강저설비검사성본등。
Introducing USA and Netherlands type 480,000 tons/year urea plant, the connection transformation of high pressure ammonium carbamate scrubber tube layer explosion - proof plate. The connection of explosion - proof plate is ＂whole ＋ bolt＂ approach. The advantage is that the form of welding is no longer used to reduce the explosion - proof plate disassembly steps, saving construction time and reducing equipment maintenance inspection costs.
