U-tube heat exchanger model meaning help

In the meaning of the U-shaped tube heat exchanger BIU500-4.O/1.6-75-6/19-2I model, B and U have clear meanings, but what does I mean?

The first letter represents the front-end structure form.； The second letter represents the shell structure form ； The third letter represents the back-end structure form. For questions like this, you can find out by looking through standard books. Is it intentional? ?
There is no BIU in the new version. The I of 151 in 1999 specifically refers to the U tube. The I in the 2014 version has been deleted. . Sir, you can find this by looking through the information. .
I represents the shell type of U-tube heat exchanger. As shown in the picture
Thanks everyone, figured it out. Please forgive me for the lax research standards before.
B represents the head type pipe box, A represents the flange type pipe box, and U represents the U-shaped pipe
It should be marked according to the new standard specification, and the transition between the old and the new must be clear.
Detailed explanation of 6.2.2 in GB/T 151-2014
Why does GB151-2014 use E instead of I?
