How should we understand that the thickness of the transition section or reinforcement section shall not be less than the thickness of the conical shell?

Both the transition section and the reinforcement section are specific areas in the equipment structure designed to enhance structural strength and stability or to facilitate connections between components. A transition section generally refers to the connecting part between two shells of different diameters or shapes (such as containers, pipes, etc.), designed to enable one shape to smoothly transition into another. Strengthening sections refer to areas of a device (often those subjected to high pressure or force) where the thickness of the material is increased or other reinforcement measures are employed to boost the overall strength and durability of the structure. “The statement that \"the thickness of the transition or reinforcement section shall not be less than the thickness of the conical shell\" means that during design and manufacturing, the thickness of the material used for connection or reinforcement should not be lower than the thickness of the main structure being connected to (such as the conical shell). The purpose of doing this is to ensure that the strength of the connecting or reinforcing parts is at least on par with that of the main structure, thereby preventing structural weaknesses caused by insufficient material thickness and ensuring the reliability and safety of the entire device. Since images cannot be provided, one can imagine a funnel-shaped container, with the conical part being the \"conical shell.\" If this container needs to be connected to another pipe at one end, a transition section may be designed at that connection point, and the thickness of this transition section should be at least equal to the thickness of the conical shell. A stiffening section is perhaps an area on the conical shell whose thickness is increased to address specific stress concentration issues. This design helps to prevent fractures or deformation in the areas where the structures are connected or where stress is concentrated. .
