Q1 2024 Fertilizer complex – Abu Qir
Chemicals & Fertilizers
Vessels and tanks in acid- and corrosion-resistant alloys for chemical plants.
4 high-resolution photos
A fertilizer complex needed storage tanks and reaction vessels for concentrated sulphuric and phosphoric acid, with a long leak-free service life.
Strict defined criteria:
Acid concentration and temperature studied to pick 904L and 316L per vessel.
Plasma cutting and cold rolling without carbon-iron contamination.
TIG welding with back purging, then chemical passivation of the welds.
Water-fill test and dye-penetrant leak testing.
Certified, documented engineering
ENGINEERING BOTTLENECKS
Any contact with carbon-steel tools leaves rust spots where corrosion starts.
The heat-affected zone resists acid less than the parent metal.
ENGINEERED RESOLUTION
Tools and work areas kept fully separate from carbon steel.
Low heat-input welding followed by passivation to restore the protective chrome layer.
