Thickness of the straight section of the expansion joint

The thickness of the straight sections of expansion joints is often less than the thickness required according to the calculations for butt-welded cylinders. If the thickness of these straight sections is checked using the formula based on cylinder thickness, it fails to meet the requirements. Yet I’ve seen many sets of drawings designed in this way. Could some expert explain this?

Is it the case that the straight sections are too small to be used, and it’s necessary to calculate using the formula for the wall thickness of expansion joints?

The thickness of the cylinder section joining the straight sections of the expansion joint must meet the calculation requirements specified in GB150.
