Sign of The Times:
Since the world's first gas station was born in the United States in the early 20th century, the new term "gas station" has been recorded in history. With the rapid development of the automobile industry, gas stations have sprung up like mushrooms. However, with the continuous growth of gas stations, in addition to the rapid development of the automobile industry, there are increasingly strict environmental protection requirements. Environmental pollution caused by oil leakage is an urgent problem to be solved by all countries.
At the beginning of the 1960s, Germany pioneered the double-layer tank for storing oil products, and this double-layer tank is made of steel inside and outside, known as SS double-layer
In the early 1980s, the American Steel Tank Association launched the SF double tank, which is lined with steel structure, and the outer tank wall is made of FRP and glass fiber reinforced plastic, which effectively resist the erosion from groundwater, microorganisms and soil environment in the buried environment
Subsequently, at the end of 1980s, the world's first FF double-layer tank made of BOTH inner and outer FRP materials came out in Los Angeles, USA. This dual-layer FRP storage tank solves the problems existing in previous oil tanks with metal structure, and is well adapted to the corrosion problems caused by the development of biofuels and alternative fuels in recent years. Therefore, it has been widely recognized and supported by laws and regulations, as well as third-party certification organizations such as UL
With the development of national economy and the continuous enhancement of people's awareness of environmental protection, laws and regulations related to environmental protection in China are gradually improved. The topic of environmental protection has attracted more and more attention, and the environmental protection of air, water and soil has become the focus of society. Through the "two sessions" during many environmental proposals, let us the whole society is aware of the seriousness of the problem, China has completed the "air ten" revision and "water ten" official release, and the "soil ten" is also coming out.
In the eighth article of the "Water Rule", it is required in the prevention and control of groundwater pollution that all underground oil tanks of gas stations should be upgraded to double tanks or anti-seepage ponds should be set up before the end of 2017.
Double wall FRP oil storage tank features:
As fuel and chemical containing liquids stored in underground steel tanks around the world have become more and more erosive over the past few decades, a large number of markets are moving towards using FRP tanks in addition to coating the inner surfaces of existing steel tanks. Because the permeability and compressive strength, FRP tanks from single-walled incline to double wall, both inside and outside double using enhanced glass fiber materials, has a long service life, corrosion resistance, prevent conductive, light weight, free maintenance, as well as good seismic performance, production process mainly has the short cut fiber injection method, the centrifugal casting method, winding molding process, such as double even the more than 30 years of glass fiber reinforced plastic production Product design and manufacturing experience, quality assurance let you rest assured.

Thick structure wall, high external pressure strength | Thick structure wall, high external pressure strength | Easy to scratch, peel or rupture |
External wall leakage can be measured by positive pressure | External wall leakage can be measured by positive pressure | The outer wall is not structural layer, can not be positive pressure leakage test |
No cathodic protection is required | External wall leakage can be measured by positive pressure | The outer wall is not structural layer, can not be positive pressure leakage test |
High voltage pinhole detection is not required | Unable to do high voltage pinhole detection | Need 35kV high voltage pinhole detection |
If found leakage can be repaired | Unable to do high voltage pinhole detection | Need 35kV high voltage pinhole detection |
The tank is light, easy to construct and cost effective | Unable to do high voltage pinhole detection | Need 35kV high voltage pinhole detection |
LZFRP production of FRP double way oil tank adopts double structure design, in the interlayer between the inner and outer wall can be installed within 24 hours of continuous monitoring system, both inside and outside wall leakage, mezzanine can be automatic induction and alarm, instant repair, put an end to the oil cause pollution to soil and underground water, in line with international environmental requirements:
1.Double - wall tank is a continuous leakage monitoring system when damaged.
2.If the inner wall of the double-wall tank is damaged or leaked, the detected liquid level in the interlayer between the inner and outer walls will drop.
3.If the outer wall of the double-wall tank is damaged or leaked, the detected liquid level in the interlayer between the inner and outer walls will also decrease.
4.If the groundwater level is higher than the detected liquid level in the sandwich and the outer wall is damaged or leaked, the detected liquid level in the sandwich will rise.

- Q: To make a high quality FRP tank, is the hardware construction important to the quality?
- Rolling drum lining non die connection has a relationship with the skilled workers, pull type extrusion will lead to damage the lining during demoulding, this is the day after the user is found can produce sweating phenomenon, is due to this reason, glass steel tank industry has a mature industrial zone in Henan Hebei, the south is not much, there are few large enterprises, relatively Guangzhou Weibo FRP existing may be the one on behalf of the industry.
- Q: How can the glass steel tank mould be made?
- 2000 cubic meters of glass reinforced plastic tanks, the cost of making a single mold is very high, and can find FRP manufacturers to site winding. If you insist that you can only use the mold with mold
- Q: In order to compare the fast inspection, the FRP storage tank is leaking
- 1., must be stored in the ground flat, to avoid glass fiber reinforced plastic storage tank collapsed.2., clean up the storage space, do not have hard objects, resulting in damage to glass fiber reinforced plastic storage tanks.3. because of the lower ignition point of glass fiber reinforced plastic storage tanks, it is necessary to keep away from the fire source during storage, and keep the storage space of FRP tanks well ventilated.
- Q: Physical properties of FRP tanks
- Good corrosion resistanceFRP is a good corrosion resistant material. It has more resistance to atmosphere, water and acid, alkali, salt, and various kinds of oils and solvents. Has been applied to all aspects of chemical corrosion, is replacing carbon steel, stainless steel, wood, nonferrous metals and so on.
- Q: How much is a 30m about the fand FRP tanks price?
- We also used to install hydrochloric acid, and last time we probably spent about 30 thousand and 5 to buy, the specific price to ask the procurement, and their product quality is not bad, we have been there to buy a few times.
- Q: What kind of industry does GRP storage tank belong to?
- FRP tanks are divided into horizontal mechanical winding FRP tanks, glass fiber reinforced plastic horizontal storage tanks, vertical storage tanks, vertical storage tanks, transport tanks, reaction tanks, various chemical equipment, containers and large series of containers
- Q: How can we produce qualified FRP tanks?
- All aspects of it, from the choice of raw materials to mold assembly, cylinder lining, winding, head of the production, assembly, pipe fittings annex, a lot of links should be done, to one by one in detail, can be a lot of words?
- Q: How is the head made of glass fiber reinforced plastic storage tank made?
- Advantages: the elastic modulus and tensile strength are much higher than the traditional manual paste process, and the stability of the product is guaranteed.
- Q: My unit recently needs 3 large tanks for hydrochloric acid. The tank, which was made of fiberglass before, is of poor quality and cannot be used for three years
- In fact, besides this I know such as PP or PE type tank or rubber lined all material can be done from the hydrochloric acid storage tank, but if the price or the strength and service life is far less than the glass steel tank, because the high corrosion resistance of FRP strength. These characteristics are not other materials instead of the.
- Q: What are the 4 layers of FRP tanks?
- Reinforcing layer: the load that bears all kinds of external pressure
