What is the Flexitank

is a flexible, light, and collapsible vessel of a new generation for the transport and storage of bulk liquids.
The Flexitank has been tested and developed under heavy-duty conditions, with a focus on safety of bulk liquid transportation.

BORNIT produces 2 basic types of Flexitanks:
A) Transport Flexitank - single use, installation in 20’ ISO containers
B) Storage Flexitanks - multiple use, long-term storage of liquids.

They can be used for liquids classified as non-dangerous according to ADR, RID, IMDG regulations.

Used materials resist a wide range of non-hazardous liquids (according to ADR, RID, IMDG).

Shape, design, materials and dimensional tolerances ensure high safety when used by customers. Long-term experience with practical use and various customers applications.

The used materials can be recycled – only polypropylene and polyethylene.

FLEXITANK is the composition of multi-layered polypropylene and polyethylene tubes. The inner liner provides the liquid tightness, whilst the outer layer provides support to the inner liner and provides high stress absorption capabilities against dynamic stresses imposed during transit and cargo handling.

Why to choose FLEXITANK?

Sea water pumping/transportation – project in USA

Example of customized specifications for special projects.

The testing was carried out on a vessel on open sea when an American company ordered our Flexitank as an alternative for transportation of desalinated sea water. The Flexitanks must absorb intense impacts of liquid during the process of loading as the filling takes place on the open sea and sea waves causes the liquid to move. Flexitank passed those tests without any damage/leakage of liquid and makes a part of the standard offer to our clients.
