How to choose a tube box flange under high pressure

Could some experts help me figure this out? I’m currently working on my graduation project, and the design pressure for the heat exchanger’s tube side is 6.7, while the design temperature is 400. The corrosion allowance for the fluid is 6, and the inner diameter of the shell is 1000. I couldn’t find a suitable tube box flange in NB/T 47023; does this mean I need to design one myself? If I design it myself, what standards should I follow?

Design can be based on 6.4 MPa.
