Is there any requirement regarding the distance of this H? I couldn’t find it in the standards; could the teachers please give me some guidance? It’s best to mention the source!

Are you sure this drawing is correct?

That’s right, I just wanted to ask if there are any requirements regarding the distance between the center line of this U-shaped tube and the weld line of the cylinder!

One only needs to consider whether the U-tube expands thermally and comes into contact with the tail flat cover or end cap

There’s also a head at the end, right? How much can the thermal expansion be?
