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
