The overall performance of these storage vessels depends on both external and internal quality. External quality can be evaluated through visual inspection and instrument testing, while internal quality is determined by the accuracy of forming, welding, and surface treatment, as well as by how strictly each production stage is controlled.

Any defects, whether visible or microscopic, can appear during transportation, storage, or operation, which may lead to equipment failure. The reliability of the tank depends on keeping every step of production under control, whether it’s forming, welding, or surface treatment.

These tanks use high-quality enamel coatings that make them durable, bringing together the strength of steel and the protective qualities of glass. Careful control at every stage of production helps keep the quality consistent and extends their service life.

When do you choose a close-type vertical glass-lined storage tank?

For processes that require less frequent cover-opening, higher storage capacity, more reliable sealing and long-term use, the enclosed structure is more suitable. The enclosed vessel body reduces the number of large body flanges, gaskets and connection joints, which makes for more compact structure and reduces maintenance needs for large gasketed joints. The close-type vertical glass-lined storage tank is especially suitable for storage, temporary holding and receiving of, or working as a buffer tank for corrosive materials or products that require long-term storage and consistent downstream process, especially for the production of fine chemicals, pharmaceuticals, agrochemicals, and chemical intermediates.

Applications
  • Raw Material StorageThe vertical glass-lined storage tank can store corrosive raw materials, organic chemicals and other materials compatible with the glass lining before the materials are fed into reactors to undergo reaction processes.
  • Intermediate Storage The storage tank can be used to temporarily hold or store intermediates for smoothly alternating between processes such as reaction, filtration, distillation and crystallization.
  • Finished Product StorageThe storage tank can be used for post-process storage fine chemicals, pharmaceutical materials, and other products requiring corrosion control, purity, and contamination control.
  • Bulk StorageThe storage tank is suitable for bulk storage and production expansion projects.

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.

Available options include horizontal tanks, open-type vertical tanks, and closed-type vertical tanks in a variety of sizes. Non-standard equipment can also be designed and manufactured to meet specific project requirements.

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.

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.

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.
