200號油換熱器設計

摘  要：本設計說明書是關于PN1.3DN500浮頭式換熱器的設計，主要是進行了換換熱器的結構和強度設計。

   設計的內容主要是根據已經選定的換熱器型式進行設備內各零部件（如接管、折流板、定距管、鉤圈、管箱等）的設計，包括：材料的選擇、具體尺寸確定、確定具體位置、管板厚度的計算、浮頭蓋和浮頭法蘭厚度的計算、開孔補強計算等。最后設計結果可通過3張圖表現出來。

關鍵詞：  浮頭式換熱器；管板；浮頭蓋；浮頭法蘭

Design of 200 # oil heat exchanger 

Abstract: The design manual is about the PN1.3DN500 floating head heat exchanger, which included technology calculate of heat exchanger, the structure and intensity of heat exchanger.

The Main design is about the structure and intensity of the design. This part is just on the selected type of heat exchanger to design the heat exchanger’s components and parts ,such as vesting ,baffled plates, the distance control tube, circle hook, tube boxes. This part of design mainly include：the choice of materials，identify specific size, identify specific location, the thickness calculation of tube sheet, the thickness calculation of floating head planting and floating head flange, the opening reinforcement calculation etc. In the end, the final design results through three maps to display.

Key word: floating head heat exchanger;tube sheet; floating head planting; floating head flange
