Double-walled oil tanks are significantly more environmentally friendly compared to single-walled ones. Currently, double-walled tanks have been widely adopted, with all oil reserve companies and gas stations now utilizing them. What do you know about double-walled oil tanks? Next, the editor will introduce the advantages of these tanks.
1. Security Features
The steel-reinforced glass fiber double-layer structure employs a patented processing method between the internal steel shell and the external reinforced glass fiber layer, creating a 3.5mm gap. In the event of an internal shell leak, the hazardous contents are confined to this gap and will not spill out to contaminate the external environment.
The inner layer is manufactured from 6mm-8mm thick special steel plate, offering significantly enhanced strength compared to the standard 5mm thickness of a single-layer storage tank.
The outer layer consists of a reinforced glass fiber layer, exceeding 4mm in thickness, offering strong corrosion and electrical erosion resistance.
The patented process technology between the two layers ensures a 3.5mm gap, eliminating potential safety hazards at their source.
2. Environmental Features
Single-layer steel storage tanks, buried underground for years, are subject to erosion from groundwater vapor and electrolytic corrosion.
The double-layered structure, with a 3.5mm gap inside, features an outer FRP layer to ensure that leakage does not directly seep and contaminate soil and water sources.
The outer FRP does not undergo electrolytic corrosion with groundwater, saltwater, etc.
The outer FRP will not corrode when exposed to gasoline, diesel, or leaded gasoline.
The leak detection instrument can monitor around the clock, eliminating potential pollution risks.
Leak detection systems facilitate the inspection and maintenance of storage tanks, thereby safeguarding the original ecological environment of the soil.
3. Economic Characteristics
The high safety and environmental performance of the S/F double-layered storage tank also indirectly reduces the users' operational costs. The use of this product eliminates the need for an underground oil storage room, as the tank can be directly buried underground. The lifespan of the S/F double-layered storage tank is 3-5 times longer than that of a standard tank, ensuring at least 30 years of safe operation.
④ Easy installation, significantly shortening the construction timeline and reducing cost investment.
The maintenance requirements for the S/F double-walled storage tanks are one-tenth of those for standard tanks, significantly reducing maintenance costs.
The utilization rate of the S/F double-layer storage tanks is significantly higher than that of single-layer tanks, ensuring high efficiency of equipment operation and high cost-performance of products.
The efficient use of the S/F double-walled storage tank has significantly protected and conserved energy, avoiding severe losses caused by energy leakage.
Double-walled oil tanks, with their environmental-friendly, safe, and cost-effective features, are meeting the needs of the times and have become the energy equipment for storing oil in various storage facilities.
