Ceramic fiber products are generally not used for water pipes and pipelines. These products are known for their high temperature resistance and thermal insulation properties, making them suitable for high-temperature applications like industrial furnaces and boilers. However, they are not designed for water conveyance due to their porous nature and potential for water absorption, which can lead to structural degradation over time. Traditional materials like PVC, copper, or stainless steel are more commonly used for water pipes and pipelines due to their durability and resistance to water damage.
