Can ceramic fiber insulation materials be used in water pipes or water tanks?

Ceramic fiber insulation materials are generally not recommended for use in water pipes or water tanks. These materials are designed for high-temperature insulation applications and are not suitable for contact with water. They can degrade when exposed to moisture, which can lead to a loss of insulating properties and potential health risks due to the release of fibers. Instead, materials like polyurethane foam or fiberglass insulation, which are designed for water contact and have good moisture resistance, are typically used for insulating water pipes and tanks.
