Product Description

*Strategic and technical cooperation with South Korean EI company.

*Patent technology of United States STI company  (Patent no. :464039,4655367)

*The industry standard "Steel and glass fiber reinforced plastic Atmospheric  buried horizontal double tank"

*The United States UL certification





The inner pot is made of 8 mm thick steel plate, the intensity is greatly increased

Outer layer is 4 mm thickness of strong glass fiber layer which has strong corrosion resistance and electrical erosion resistance;

There is a 1.2 mm of penetrating clearance between the two layers to guarantee the leak sensor detection of leakage timely, stop the pollution to the outside environment from the source.


The outside FRP layers won't have electrolytic corrosion phenomena when met with groundwater, saltwater, gasoline, diesel and leaded gasoline; Leak detection systems constantly monitor 24 hours, put an end to the pollution and protect the ecological environment of the soil


More than 30 years safe service life and directly buried way construction, comprehensive cost is more economic than the traditional single pot, construction is more simple and quick.
