Shot-blasting tanks
CDE blasts its tank production in compliance with standard NF EN 12285-1 and the specifications of the coatings used.
To achieve this, CDE has two blasting cabins:
– A manual cabin equipped for two blasters (20 m x 5 m x 5 m)
– An automatic cabin capable of blasting tanks up to Ø3 m and 100 m3.
The substrates to be coated are prepared by metal abrasive blasting to obtain a degree of care Sa 2 ½ or Sa 3 in accordance with ISO 8501-1, followed by careful dust removal.
Passivation pickling (stainless steel tanks)
CDE has a ventilated pickling/passivation booth (10m x 8m x 6m).
This corrosion resistance is achieved thanks to a thin transparent film of chromium oxides over the entire surface of the steel.
Polyurethane coating - Liquid paint
CDE offers several types of coating in its workshops:
– Polyurethane coating (underground tanks),
– Liquid paint coating (overhead tanks),
– Specific coatings adapted for tank interiors.
– Standard NF EN 12285-1 Underground tanks: Dielectric comb inspection (2500 V, 6000 V, 12000 V or 14000 V).
– Standard NF EN 12285-2 Overhead tanks: Inspection of the anti-corrosion coating by thickness measurement (Elcometer).
