Iran bitumen
Iran Bitumen is
premium quality of Bitumen which is
higher than ASTM quality and
exporting to worldwide market. Iran
Bitumen packed in highest standard
in new steel drum to 25 Kg meltable
bag or 1000Kg super sacks also in
bulk vessels. Iran bitumen is famous
bitumen 60/70 and 80/100 also
bitumen 40/50 with capacity of
30000MT daily production of seven
refineries around Iran. Compare of
Iran bitumen with other origin
showing the Iran is ranked No.6
bitumen producer in the bitumen
market. Iran bitumen is ranked in
No.6 country in production of
bitumen in worldwide market
Iran bitumen
has high quality in the world.
It is famous to NIOC bitumen
and available in different grades,
packing between 10000MT to 12000MT
monthly. Available packing is new
steel drum, poly bag ,Bulk bitumen
Iran bitumen 60/70,80/100,40/50,90/130,160/220
ATDM is member
of syndicate bitumen exporter and partner of most drumming
factories which has owned export
license for exporting all grades of
bitumen as per of ASTM standard such
as :Bitumen 30/40,Bitumen 40/50,Bitumen 60/70 ,Bitumen 80/100 ,Bitumen
85/100,Bitumen R85/25 ,Bitumen R90/15,Bitumen MC250 or cutback
.other grades of bitumen will
produce according to order. Bitumen?
Bitumen is produced from selected
crude oils through a process of
fractional distillation. The crude
oil is heated to temperatures of
between 300 and 350 degrees Celsius
and fed into a distillation column
allowing the lightest fractions of
the crude to separate, through
vaporization, from the heavier
fractions, which remain liquid.
The
higher boiling point fractions are
then drawn - off via a heat
exchanger and enter a vacuum
distillation column. This process
produces a short residue that is
used to manufacture several grades
of bitumen.The pressure and temperature
conditions within the vacuum process will determine the hardness of the
short residue, and as such the grade of bitumen produced.
The short residue may be further modified by'air blowing in which air is
passed through the residue at
temperatures of 250 - 300 degrees
Celsius. The above are the typical
Penetration or Paving Grades of
bitumen.
Additional processing
provides other grades of bitumen
products such as: Oxidized bitumen -
produced by more vigorous air
blowing; they are more 'rubber like'
and less temperature susceptible
than the paving grades.
Other types of Iran bitumen
Hard Grade bitumen - harder paving
grades. Cutback bitumen - blends of
penetration bitumen with solvent
such as kerosene. Emulsions -
stabilized suspensions of bitumen in
water. Polymer Modified Bitumen -
mixtures of selected bitumen with
polymers such as thermoplastics or
elastomer
