Double-wall FRP oil storage tank, or double-wall oil tank for short, is made by adding a fiber reinforce plastic layer on the single-wall steel tank. There is a high-efficient leak detection device set between the inner steel tank and outer FRP tank to supervise the whole process for 24 hours. Once leak accidents occur, the sensor of the leak detection device can monitor the fluid level and send an alert to ensure the safe use of the oil tank.
The high safety and environmental protection performance of double-wall FRP oil storage tank, indirectly, drives cost down for customers. Simultaneously, double-wall oil tank has service life at least five times longer than ordinary oil tank.
There is a double-wall FRP oil storage tank with two saddle supports.
DFOST-01: Suitable accessory can be offered with double-wall FRP oil storage tanks.This is a double-wall FRP oil storage tank in green.
DFOST-02: Double-wall oil tank has a fiber reinforce plastic layer outside single-wall steel tank.
This picture shows a schematic diagram of the double-wall FRP oil storage tank.
DFOST-03: Many small parts make a integral double-wall oil tank system.

Note: Other sizes can be customized to meet your needs.
Firm structure high strength: Inner wall adopts special steel plate, while outer wall is fiber reinforce plastic layer. Both of these two layers have higher strength than ordinary tank walls.
Advanced detection device digital control: Leak detection device can monitor the fluid level for 24 hours and send an alert when a leak accident occurs to ensure the safe use of the oil tank.
Easy to install cost-effective: The integral double-wall construction makes handling and installation easier and safer, which results in cost savings.
Save energy protect environment: Using double-wall FRP oil storage tank, you can avoid loss caused by energy leak and protect environment.
