What is a polyethylene tank?

Today, polyethylene tanks are produced to store water and liquids compatible with polyethylene and transport materials compatible with polyethylene. These plastic or polyethylene tanks are usually used in construction industry, agriculture and chemical industry for storage and transportation of water and other liquids. Polyethylene tanks, also called polymer tanks, are popular for many reasons and have overtaken other tanks used in the past.

The features of polyethylene tanks

Polyethylene tanks are easily accessible and easily portable.

The price of polyethyen tanks is quite lower than metal tanks or other materials and uses these tanks.

The range of use of polyethylene tanks depending on their gender and raw materials and compatibility with a wide range of materials and fluids.

It can be designed and manufactured for any space and environment.

Polyethylene tanks are very light weight and are very simple to move and transport.

How to make polyethylene tanks

Polyethylene tanks are produced by rotational molding process. At the beginning of the production process, polymer powder materials are combined with UV protective materials and poured into a two-piece mold. The percentage of UV protective substances used in this mixture depends on the final use of the produced tank. When the mold is closed, the mold is heated in a hot furnace with a suitable temperature. During the heating process, the mold rotates 360 degrees in two directions. These movements make the resulting mixture sit on all parts of the mold as the compound melts. After the process is completed, the mold is transferred to a cooling room where the temperature is slowly reduced and the tank is removed from the mold as the temperature decreases.

Polyethylene reservoir capability

Polyethylene tanks are made of HDPE and MDPE polymers, which are resistant to most substances such as pesticides and chemicals. However, polyethylene tanks should not be used to store fuels such as gasoline, as these materials can make the plastic loose and brittle. Only certain types of polyethylene can be suitable for this task, whose raw material is either not available in Iran, or the finished price of the product is much more expensive than metal tanks. For this reason, we recommend using a variety of standard and protected metal tanks for long-term storage of fuel according to the standards of the oil company.
