OKET's FRP double wall tank is used in Petro-China's gas station in cold area

Background

PetroChina Hegang Nanshan Gas Station is located in the northeastern tip of China's Heilongjiang Province，the area is located in the cold zone, and in mid-October every year it enters the cold winter.?

Petro-China Considerations

?Due to the cold weather, the construction period should be as short as possible.

?An under-drive tank area design is required.

?Hope the total cost is as low as possible.

Construction and installation of A&Z's 3DFF? double-wall storage tanks is quick and easy, with the installation can be directly buried with ordinary crushed stone without building a concrete pressure chamber. This can greatly shorten the construction period while ensuring full utilization of space. What makes Petro-China more satisfied is the total cost compared to other methods is more economical.

Contractor's concern facts:

Will the storage tank freeze?

Does the cold weather affect the water injection process? Does this water injection process necessary?

Will the brine liquid used for leak detection freeze?

A&Z's 3DFF? double-wall storage tank technology original from the Canadian company ZCL. The temperature in many areas of Canada is lower than Northeast of China, and the 3DFF? double- wall storage tank has a market share of nearly 90% in Canada. Therefore, There are enough cases proved that the 3DFF? double-wall storage tank is completely adaptable in the alpine environment and will not be frozen.

The construction process must be filled with water. After water injection 48 hours test, natural settlement can effectively prevent the risk of sinking or floating tanks.

The leak detection liquid of A&Z's 3DFF? double-layer storage tank is brine, and the cold weather is fully considered when configuring, not only will it not freeze, but also will not precipitate due to low temperature.

What Petro-China and Contractors Say About 3DFF? Double wall Tanks？

The storage tank can be used in the alpine area, The leak detection method of the brine filling the middle layer will not be affected by the cold weather. Taking into account the civil construction cost and construction period, 3DFF? double wall is adopted construction under the driveway, and the overall cost is lower than other types.

We are very satisfied, and we are very grateful to A&Z Company, OKET Group's products and services, we have always trusted.
