In cooperation with our company FLUID UTVA AD Pančevo, we produced our first swap tank for transport of liquefied petroleum gas – LPG (ADR Class 2).

Swap tanks are employed for the exchange of goods and are suitable for transportation by road, rail and Ro/Ro ferry services including interchanges between these modes of transportation.

 Our first swap tank CA-S-16-LPG is attached to the used two axle vehicle SCANIA P94 GB4x2NZ 230. To this purpose, we had to modify the chassis of the vehicle. Here we considered the body manual of the manufacturer SCANIA. During the chassis modifications we reduced the axle distance and rear overhang.

Swap tank CA-S-16-LPG is constructed for transporting propane, butane and its mixtures (LPG) on a truck with two axles. It has a pressure vessel and base frame 15’ x 8’ which can be secured by twist locks or pins of road vehicle complying with the relevant requirements of ISO 668 “Series 1 freight containers – Classification, dimension and ratings”. Swap tank is mounted on truck chassis in according to the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR).

The vessel is calculated according to ADR 2009 and corresponding European norms. The total volume of the vessel is 16000 L. One compartment vessel has two aluminium baffles which reduce dynamic loads due to motion of fluid. Vessel is equipped with necessary connecting nozzles and attachments.

The base frame of swap tank is equipped with four bottom corner fittings. Also steering tunnel and connection places for supporting legs are provided in accordance with standard SIST EN 284:2007.

All tubes, fittings, valves and equipment are mounted in a long stainless steel protection box on the right side. There are two separated doors to open the box.

Discharge installation on CA-S-16-LPG allows direct loading or loading through hose reel and gravity unloading or unloading with pump directly or through hose reel. With this installation is also possible to pumping LPG from one tank to another through hose reel and pump.

 In installation is bottom valve connected with hydraulic driven pump through ball valves that enable the different functions of installation. An external bypass valve is installed after the outlet of the pump. A differential valve and degas unit with meter in combination with an electronic counter is used. The printer is installed in the truck near driver seat. At the left side of the protection box is installed an aluminium hose reel with hydraulic motor to roll up and down the hose. Quick-acting hose-end valve is fixed at the end of the hose. To ensure total functionality of discharge installation are installed three male ACME connectors with ball valves. All pipelines are made of stainless steel.
