Vertical Storage Tanks
Vertical storage tanks stand on legs or a flat foundation and hold a large volume on a small footprint. They suit liquids stored at atmospheric or low pressure.
We fabricate vertical tanks in carbon steel and 304/316L stainless steel. Smaller tanks are completed in our workshop and shipped whole; large tanks are prefabricated in Jinxian and erected on site.
Options include external coating, insulation and PE lining of carbon steel tanks for corrosive media. Tanks built as pressure vessels fall under our Class D licence TS2236612-2027.

Which type of tank suits our chemical, oil, water or food medium?
It depends on the medium, temperature and pressure. Carbon steel is common for fuels and water, 304 or 316L stainless steel for food and many chemicals, and PE-lined carbon steel for some corrosive media. Send the medium data and we propose a material.
Can a tank be customized for corrosive media, low temperature or special cleaning?
Yes. We offer stainless steel, PE lining, low-temperature steels for design temperatures down to −196 °C, and nozzle, manway and drain layouts to your cleaning procedure.
Do you build large tanks on site?
Yes. Plates are cut, rolled and bevelled in Jinxian and the tank is erected on site. Our references include a 10,000 m³ wax-oil tank.
What should we check before accepting a fabricated storage tank?
Material traceability to the MTRs, weld NDT records, the pressure or tightness test report, dimensions and nozzle orientation against the drawing, and surface preparation and coating against your specification.
