When pipelines in the oil tank area pass through walls, and sleeve-type passages are used to pass through firewalls, what material should be used to fill the gap between the main pipeline and the sleeve?

When pipelines in the oil tank area pass through walls, and sleeve-type passages are used to pass through firewalls, what material should be used to fill the gap between the main pipeline and the sleeve? The main gaps are small, but safety requirements demand that they be sealed off! Could everyone share their plans! Full of gratitude!
None of our irrigation areas are blocked; we have seen areas that are blocked. Filled with cement, fireproof foam, plastic, etc
The gap between the main pipeline and the casing is filled with refractory material
