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,
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:
    • Meets EN 13094, on the right or back side according to the driving direction, gravity discharge through the discharge piping line extending from the bottom valves up to the couplings, at such a slope in order not to remain any liquid in the line after discharge,
    • ISO 3834 Welded production quality qualification approved, exported patent padded welded discharge pipes.
  • It is suitable for the chemical substance content from the stainless material in accordance with the standards,
  • Filling couplings that prevent the release of the transported chemicals to the environment,
  • Special designed suitable to body design, horizontally and vertically angled, rollover safety monoblock chassis,
  • OMEGA® monoblock connection saddles provide a rigid structure with excellent fit to the chassis mounting slots and increase strength, Tension reduction gaps reduce the tension by distributing the force coming from the road conditions to the running group,
