What does Clause 5.9.6 of GB151, “Support plates for thickened ring plates”, mean?
Reply #22009-10-28
From past experience, it is necessary to thicken the support plate at the floating head end (also known as baffle plate) in order to support the weight of the heat exchange tubes, the floating head sheet, and the hook rings, thereby preventing excessive deflection. Thicking the ring plate serves to reinforce the support plate and prevent it from deforming It is possible to take into account situations where the unsupported span of the heat exchange tubes exceeds the maximum unsupported span specified in GB151

In my understanding, it involves thickening the baffle thickness slightly to serve as a support ring plate at the floating head end
