Bulk Cargo Transportation in Flexitanks

Transportation in flexitanks is one of the new trends for the transportation of a wide array of non-hazardous liquid goods, chemical products, and industrial materials.

Flexitanks are multi-layer sealed containers designed for the transportation of bulk cargoes; their capacity is up to 28,000 liters.

This container type when used in combination with a multipurpose container ensures the affordability of container transportation of any non-hazardous liquid cargoes.

We perform international cargo transportation to/from Europe, China, South and North America, and Asia.

We ensure stringent control at all stages of our supply chain.

We guarantee cargo safety: Goods are delivered to consignees with their seal.

Flexitank Design

Flexitanks is a flexible container designed for the transportation of liquid food cargoes and non-hazardous chemical cargoes.

Capacity of this polymeric elastic container is 10-28 thousand liters.

The outer shell is made of laminated woven water-resistant polypropylene.

The inner shell is made of 3-layer welded polyethylene with d in 3 layers with a blocking layer.

Special fittings are provided for draining and filling the flexible container used for storing food products and chemical non-hazardous products.

Its inlet valve can be located at the top or bottom of a flexitank.

To normalize pressure when transporting gas-emitting liquids an air valve is provided.

Flexitanks are supplemented with bulkheads with special holders that limit movement of the cargoes if container sways.

Advanced technical solutions allow for maintaining the optimal temperature of transported products.

When folded, the container takes up only ¼ cubic meters.

Flexitank fits a standard 20-foot container and can be delivered by road, rail and sea transport.

Flexitanks are a worthy alternative to ISO tanks, tank cars, barrel, and other containers for cargo transportation and cargo storage.

High reliability of this container type is attested by ISO certificates.

Use Cases

Flexitanks are a preferred way to transport the following types of cargo:

  • Containerized food products: Juice concentrate, syrup, milk, glucose, wine, wine materials, tomato paste, sauces, sorbitol, mineral water, food colorants, egg white, etc.;
  • Oils and fat-and-oil liquids. Cargo transportation of vegetable oil, palm oil, fish oil, animal fat is carried out by special flexible tanks designed for oil and fat-and-oil products. Transportation of sunflower oil in flexitanks is in great demand. China is the key customer;
  • Non-hazardous chemical liquids and petroleum products, i.e. mineral oils, lubricants, soluble paints, glycerin, detergents, synthetic latex, paraffins, emulsions, and other non-intrusive chemicals;
  • Liquid bitumen. Heat resistant flexitanks are used for transportation. They are designed for the transportation of goods at 60°C – 90°C.

Advantages of Transportation in Flexitanks

Thanks to their quality technical features flexitanks increasingly phase out conventional tank cars, barrels, and ISO tanks.

Reasons for this trend are listed below:

  • Enhanced cargo safety in case of multimodal container transportation;
  • Clean inner section of flexitanks: No need to prepare containers;
  • Inert material of the liner excludes interaction with the contents when the temperature rises or during long-term transportation;
  • Structural integrity provides for protection against pollution and enables to maintain the quality of goods;
  • No special skills required for maintenance of the elastic insert;
  • Flexitanks can be transported, in addition to containers, in carbodies, provided that they are fixed with reinforced anti-vibration belts;
  • No need to transfer or repackage cargo;
  • No cost associated with container cleaning and returning: Used disposable inserts are disposed and recycled;
  • Reduced shipping costs: Shipping by water transport is normally much cheaper than tanker shipments.

Preparation for Transportation by Flexitanks

First, flexitank is prepared for transportation in a special depot or warehouse.

The container is inspected and cleaned, if necessary.

Its walls are covered with cardboard, fiberboard or polyethylene foam, at least 3 mm thick.

This reduces friction of the polymer insert against the metal surface.

Flexitank unfolds inside the container ensuring that the ball valve is located near the door.

Bulkheads are then installed and the tank gets filled.

When 2/3 of the volume is filled the air valve is opened to reduce pressure.

When the container is 90% full the pipe is closed.

The container is sealed once loading is completed.

Containers equipped with flexitank can be delivery for loading straight to the production facility.

Unloading is performed by gravity, provided the unloading sleeve is placed below the bottom of the container.

In all other cases liquid is drained using the relevant pumping unit.

Spectransgarant transportation company is engaged in setting up flexitank transportation by sea, road and rail transport.

Goods are shipped by carefully planned routes in strict observance of the relevant national and international regulations.

We use certified flexitanks only.

We do our upmost to ensure fast delivery of your cargoes.

Our managers will help you select the optimal mode of transport.

We offer optimal pricing for international cargo transportation. Call us at +7 (495) 589-19-77 to learn more.
