Understanding the parameters defining piping in GB151

I would like to ask regarding the explanation on page 23 of GB151 concerning the limiting circle parameters; what exactly does b1 refer to? I can’t understand it

b1 refers to the distance from the outer diameter of the hook loop in the floating head to the inner diameter of the cylinder! This is my personal understanding for reference only!

I answered incorrectly; my apologies! B1 refers to the distance from the outer diameter of the floating head tube sheet to the inner diameter of the cylinder; this ensures that the tube bundle can be easily pulled out after the floating head is removed, thereby facilitating the cleaning of the tube bundle! I answered incorrectly; my apologies! :L
