Consultation: There is a conventional shell and tube heat exchanger, shell side oil, pipe side Freon, design pressure shell side 1.0 MPa, pipe side 1.4 MPa, then how to deal with the ratio of flaw detection? We don't want to explore the shell side.
According to the definition of opening reinforcement, that reinforcement calculation is all right, except that the fillet weld is completely represented by the forging, the shell form is all right, and the shell material should be forged.
