Why can the span of the pipes outside the device be larger than that inside the device?

Why does the design manual allow the pipe span to be larger outside the device than inside it? Allowing for a larger span means allowing for greater deflection. Can’t the deflection inside the device be a bit larger?
Because it has fewer environmental constraints, the allowable deflection limit is higher. Designers can sacrifice some degree of \"smoothness\" while ensuring the strength of the pipes and preventing vibration, in order to achieve a larger span for the pipe gallery and thus improve economic efficiency. Inside the device, it’s like being in crowded blood vessels; the pipes must be precisely fixed within a limited space, as any excessive movement or sagging can directly lead to problems related to safety, functionality, and reliability. Strict deflection control is a necessary cost to ensure the safe and stable operation of the device. The differences outlined in the design manual reflect the core principle of pipeline design, which emphasizes safety and functionality within the device, while prioritizing cost-effectiveness and strength outside the device.
