Classification of shell-and-tube heat exchangers
Thread Content
Dear teachers, should the shell-and-tube heat exchangers mentioned in 1.4.1 of the Fixed Capacity Regulations meet the scope applicable to 1.3, and then be classified according to Figure A-1 or A-2?
According to the design codes for fixed-volume vessels (GB 150), for shell-and-tube heat exchangers, the applicable scope of 1.3 must be satisfied first, followed by classification according to Figure A-1 or A-2. Therefore, if the operating conditions of the shell-and-tube heat exchanger meet the requirements within range 1.3, it is necessary to select the appropriate category based on its design parameters and operating conditions, and to take corresponding design, manufacturing, and inspection measures. .
