Glass Lined Storage Tank
Corrosion-resistant storage vessels for chemical, pharmaceutical, and industrial applications
Glass lined storage tanks undergo a 20 kV spark test (7 kV for site acceptance) to ensure complete enamel coverage on the steel interior. This creates a strong protective barrier against inorganic acids, organic acids, solvents, and weak alkalis across different concentrations. The main exceptions include strong alkalis, hydrofluoric acid, fluoride-containing media, and phosphoric acid above 30% concentration at temperatures over 180 °C.
These storage vessels are available in both horizontal and vertical designs, including open- and closed-top configurations. They are available in a wide range of sizes, with flexibility to produce customized models to meet specific project requirements.
Open-top vertical glass lined storage tanks are equipped with welding neck flanges that match the tank diameter. They are designed for nominal pressures of up to 0.6 MPa, with capacities ranging from 50L to 200,000L, and can operate within a medium temperature range of 0 to 150 °C.

View MoreChemical, pharmaceutical, and petrochemical industries often deal with aggressive media that can wear down equipment over time, making corrosion resistance a critical factor in vessel design and material selection. For this reason, corrosion resistance is one of the first factors engineers consider when selecting storage or reaction vessels.

- The inert glass lining prevents contamination during storage, keeping the purity, flavor, and color of materials intact. Substances such as latex, resin, and viscose do not stick to the smooth surface.
- Thanks to their smooth and non-stick surface, the storage tanks are easy to keep clean. A quick wash is usually enough, which saves time and makes regular maintenance simple.
- Some materials can harden at room temperature, so to prevent this from happening, heating plates can be installed on the outside of the tank, to allow the contents to warm up gently and stay ready for use.
What types of media can glass lined storage tanks handle, and which are not suitable?
These tanks can resist corrosion from inorganic acids, organic acids, organic solvents, and weak alkalis at different concentrations. However, they are not suitable for storing strong alkalis, hydrofluoric acid, fluoride-containing media, or phosphoric acid with concentrations above 30% at temperatures higher than 180 °C.
What types of glass lined storage tanks are available, and is customization supported?
Available options include horizontal tanks, open-top vertical tanks, and closed-top vertical tanks in a variety of sizes. Non-standard equipment can also be designed and manufactured to meet specific project requirements.
What materials are used in open-top vertical glass lined tanks?
These storage tanks are made of steel with an internal glass lining. The steel gives strength and rigidity, while the glass provides corrosion resistance. The lining also creates a smooth surface that is chemically stable, moderately heat resistant, and easy to clean.
How is the external and internal quality of vertical glass lined tanks assessed?
External quality is evaluated through visual inspection and testing instruments to check for surface defects. The internal quality depends on some production factors, including proper forming, welding, and surface treatment, as well as strict quality control at every stage of manufacturing.
What options are available for horizontal glass lined storage tanks?
There are several options to choose from. Some tanks have a large side opening with a half-pipe coil jacket and can be fitted with platforms, railings, and ladders for easier access. Others come with heating evaporators, making them suitable for applications where temperature control is required.
