Glass Lined Column
Corrosion resistant columns for handling distillation, extraction and absorption applications
Glass lined columns are suitable for demanding industrial processes where materials can be highly corrosive or reactive. The steel shell gives the column the strength to handle pressure, while the glass lining protects it from corrosion and keeps the process media from touching the metal. This design makes the corrosion resistant column safer, more stable, and longer-lasting for processes such distillation, absorption, and extraction. They are commonly used in distillation, extraction, absorption, and other separation or treatment processes.
These corrosion resistant columns meet GB25025-2010 or ASME standards, ensuring reliable performance and compliance with industry requirements. The design brings together the chemical inertness of glass with the strength of a steel structure, resulting in equipment that is both durable and resistant to corrosion.
Besides the standard glass lined column models, customized solutions can be provided, including distillation, extraction, and absorption columns, as well as other glass lined process equipment tailored to specific operating conditions.
- Glass lined columns can handle a wide range of corrosive media, including strong acids, oxidizing agents, and organic solvents. The only limitation is with solutions that contain fluorine ions, which are not suitable.
- The inner glass surface is smooth and non-porous, making it resistant to staining and much easier to clean compared to bare metal.
- Because the lining is impermeable, it prevents cross-contamination between batches. At the same time, the chemical stability of glass keeps the purity, color, and properties of the stored or processed materials intact.

We also provide for Glass-Lined Equipment
Can glass lined columns be customized? What types are available?
Yes. Customization is available for different column sections, including hose-wound glass lined sections. Depending on project needs, tailored equipment such as rectification towers, extraction towers, absorption towers, and other non-standard glass lined equipment can also be supplied.
What features of glass lined columns ensure performance and material quality?
One of the main advantages is the smooth inner surface, which doesn’t easily stain and is simple to clean. Since the glass lining is impermeable, it prevents cross-contamination, and its stability helps preserve the purity, color, and flavor of the materials during processing.
