The pontoon "KonTEK" has some distinctive design features:
- during manufacture each float undergoes a leak test with overpressure of 1.5 kgf/cm2 (0.15 MPa). The embodiment of floats ensuring the structure buoyancy allows for easy (as automobile tire pressure) leak test with residual pressure of 0.3 kgf/cm2 (0.03 MPa) and checks during manufacture, after mounting and in operation (tank maintenance).
- original design of the peripheral seaing (combined-type seal) for air-vapor volume in a gap between the tank wall and central pontoon body ensures:
- the sealing element is reliably forced with flat springs to the tank wall at 200…250 mm above the product level with force up to 4 kg/rm);
- endurance of sealing elements without replacement for the whole pontoon lifetime;
- reduced product evaporation due to capillary effects in case of loose rust on the tank wall;
- operation practically in any products;
- sealing resistance to steam (tank steaming) up to 250 îÑ and excellent fire and explosion safety operation conditions;
- flexible (pivot) joint of floats in rows ensures pontoon functionality under earthquake of magnitude up to 7;
- the pontoon is made of domestic materials used in aircraft and rocket industries that satisfy the highest quality requirements.
The pontoon "KonTEK" is completed with an earthing system, anti-turning devices and, if required, vent pipes, floating sampling devices.
The above mentioned features of the "KonTEK" pontoon give
the following advantages:
- increased warranty period – up to 5 years;
- repair-free service life – up to 20 years;
- pontoon serviceability;
- maximum temperature of 250 îÑ for tank steaming;
- increased fire and explosion safety operation of tanks.
