What is a flexi tank?



A flexi tank is a type of bag that transforms a standard 20-foot container into an efficient carrier for bulk liquids. Standard flexi tanks are made of polyethylene and polypropylene, with capacities ranging between 16,000 to 24,000 liters. Flexi Tanks are used to carry a variety of liquids, food and petrochemical products. Flexi Tanks reduce the cost of transporting hazardous materials.

Isotank is a type of steel tank container for marine transportation of liquids and gas, as bulk cargo. As a representative of the international shipping lines active in Iran, Pacific offers the best services for marine shipping of isotanks, with the most competitive price. The Pacific office in Bandar Abbas can ship the following type of cargo for its customers:

Transportation of dangerous petrochemical products and gases with isotanks


Transportation of white spread with isotanks


Transportation of base oil with isotanks


Transportation of hydrocarbons with isotanks


Transportation of RPB with isotanks



Transportation of RGO with isotanks

The load capacity of an isotank is up to 23000 kg; Nevertheless, the increase in cargo volume due to gas production during the shipment would limit the loading up to its available limit. Disregard of this fact may result in overflow of cargo from the isotank, which would then be discharged from the ship. Hence, it is necessary that the corresponding MSDS information of the cargo be sent to the shipping company in advance of the isotank loading, in order to act according to the procedures and inquire the loading capacity from the relevant experts.


How many cubic meters is the loading capacity of an isotank?


The density of the goods determines the volume of goods to be loaded into the isotank (iso tank volume).


Are the inside of the ISO tanks washed?



The concern of most customers is that the remnants of the previous cargo carried by isoank will affect their cargo and reduce its quality. For this reason, all isotanks are being washed prior to new loading (iso tank washing).
