manufacturing process

Cistas Industrial manufactures fuel tanks according to the necessary guidelines ensuring the quality standards that allowed us to obtain in the year 2007 the Quality Certificate ISO 9000, awarded by the Spanish Association for Standardization and Certification (AENOR).

All the materials used in the fuel tanks manufacture are checked and a lot number is assigned to them, so that, the product traceability is maintained in the corresponding manufacture order. The manufacturing process includes shell execution, this, together with tanks bottoms, finishes with a submerged arc welding process that guarantees leak-tightness in our tanks. After that, and having carried out leak tightness pertinent test, tank double wall cover is done (checking again the welding) while creating the vacuum within the interstitial chamber existing between both walls.

After finishing the manufacturing process, the tank is prepared to be painted, this process take place in our industrial painting booth, which ensures a better finish of the product the drying time is highly reduced) and foments environmental impact reductions. Once, the tank is dry, thickness measuring and tests are carried out, according to those required in UNE manufacturing standards. The manufacturing certificate issued, specifying all the information, will serve as a veritable proof of the full process.
