High-Purity Porous Alumina Ceramic Tube for Industrial Filtration & Separation

Our porous alumina ceramic tubes stand out with controllable and uniform pore sizes. Custom pore sizes ranging from 5μm to 100μm are available with balanced porosity and stable gas and liquid permeability. The interconnected microporous structure delivers precise filtration performance, effectively removing suspended solids, colloids, and tiny impurities to ensure consistent and reliable fluid treatment results.

Designed for harsh industrial conditions, our alumina ceramic tubes offer exceptional durability. They can withstand high temperatures up to 1700°C and feature excellent thermal shock resistance, preventing cracking and deformation under frequent temperature changes. With superior acid and alkali corrosion resistance and a Mohs hardness of 9, our products outperform traditional plastic and metal porous parts, extending service life and greatly reducing maintenance and replacement costs.

These versatile ceramic tubes cover diverse application scenarios, including chemical gas aeration, food and beverage purification, industrial wastewater treatment, petrochemical separation, and laboratory analysis. Their reliable electrical insulation avoids medium contamination and potential safety hazards, fully complying with strict industrial standards.

We provide full customization services for pore size, dimensions, wall thickness, and end face structures. With strict full-process quality control, both standard and customized porous alumina ceramic tubes maintain stable performance and high batch consistency.
