Technoexport Storage production focuses on large capacity steel storage tanks for crude oil, petroleum products and industrial chemical storage.

The company’s range of products later expanded to include supplies of gas-holders, storage silos, fermentation units, biogas reactors and both pressure and non-pressure vessels for the chemical and food processing industries.

We also manufacture and install industrial steel structures and piping, with an option to include deliveries of filling and pumping stations. Our original focus of production and subsequent development have established Technoexport Storage on refinery equipment and other petrochemical and chemical operation markets. All products are continuously modernised in the light of current developments in particular fields and related to market demands.

Besides the construction of new storage tanks, we mainly carry out the following activities in refineries:

  • Repairs, maintenance and modernisation of tanks in operation
  • Repairs and maintenance of steel structures, piping bridges and special technologies
  • Repairs and maintenance of piping distribution networks
  • Repairs and maintenance of technical equipment

The above mentioned activities are performed during standards testing or during production equipment shutdown.

There is a special requirement for work safety in petrochemical and chemical operations with a danger of explosion; to comply with which the company has adopted special internal regulations.
