Tank Body
  • Cylindrical cross section design conforms to EN 14025 standard,
  • Dished heads at front and rear, in accordance with EN 14025 design standard internal baffles fit the selected number of compartments,
  • ISO 3834 Welded manufacturing quality qualification approved,
  • Unique body structure in the tanker manufacturing sector with a smooth surface, with a minimum number of (T) joints, produced by the longest welding seam technology in the cylindrical structure, seamless, integral plates and their welded joints,
  • Using seamless high-performance robotic welding technology, welding faults on the body due to tension and human factors are minimized and secured against impact,
  • Tanks and connections are tested with the method of analysis of the end elements under maximum allowable load to increase the strength of the body and reduce the tension effect at the frame junctions. The robotic welding technology is applied to the OMEGA monoblock connection saddles,
  • The slope in the chassis design allows complete discharge of each compartment of the tank, with no liquid remaining,
  • The cleaning manhole for cleaning inside tank and its each compartment when necessary,
  • Air gap safety against expansion and overflow conforms to EN 15120 standard
  • The tank body is covered with rock wool which protects the product temperature and fluidity for a long time and provides full heat insulation,
  • Insulation applied to the body is wrapped around the circumference to prevent sagging, protects against external factors, sealing with lath and heat resistant rubber, visual aesthetically insulated isolation coating and front and rear isolation dished heads,
Heating System::
  • On the inner bottom of the tank, the product fluidity is provided homogeneously with hot water or steam vapour flow through stainless pipes, resistant to working temperature,
Loading/Discharge Line:
  • Loading Line:
    • Depending on the driving direction, it is filled through the right-handed couplings from the bottom or through the manhole covers or closed-circuit filling couplings from the top.
  • Discharge Line:
