Is it necessary to install a fixing pier in the middle of a roughly 45m long DN150 buried steam pipeline?

For a DN150 buried steam pipeline approximately 45 meters long, with both ends extending above the ground, is it necessary to install a fixing pier in the buried section?
Buried steam steel-in-steel pipelines?
Fixed supports and bellows compensators are required.

It is better to consider the settlement issue or use fixed piers.

Theoretically, it is possible to omit the intermediate fixed pier if the two ends are used as sliding points and the compensation amount is sufficient. However, the compensation amount at both ends is twice the length, and the sliding amount is significant; in the actual design process, a fixed pier is placed in the center, so the compensation amount at both ends is only one-fourth of that in the case where no fixed pier is present in the center
