Introduction of STG Ampute Aluminium alloy explosion-proof ball

The barrier explosion-proof materials produced by our company is a special aluminum alloy foil made by hot rolling process. It changes the mechanical properties of the material and is cut and stretched to form a cylinder or spheroid with a high-porosity network structure. This materials can effectively solve the problem of breakage during long-term use, and fundamentally solve the problem of blockage of pumps, meters, valves and various oil circuit systems. The material is widely used in buried storage tanks, hazardous chemicals transport vehicles, oil tankers, military equipment and national energy strategic reserve stations.
Domestic customers all over the country, such as Beijing, Shandong, Xinjiang, Jiangsu, Guangdong, Guangxi, Shaanxi, Sichuan, etc. The products are also sold overseas to many countries, such as Russia, Kyrgyzstan, Australia, Norway, etc.

Product safety 

Protect the safety of inflammable and explosive liquid and gaseous hazardous chemical storage and transportation containers and devices, and effectively inhibit the explosion of hazardous chemical media (including gasoline, diesel, methanol, liquefied petroleum gas, etc.) in the event of open flame, electrostatic spark, welding, shooting, collision, wrong operation and other accidents.

A storage tank container equipped with a barrier explosion-proof material, once it encounters an open flame burning, the flame height of the burning is reduced to about one-thirtieth of the original, which is conducive to extinguishing the fire.

New generation of product advantages

Better material properties
In cooperation with the team of materials science professors of Tsinghua University, the material research and development and upgrading of the previous metal isolation products have improved the ductility and forming strength of the materials
Multi-variety design
Product design of metal isolation materials and non-metal isolation materials, fully consider the use of different environments;
Adapt to more demanding conditions of use
It can pass the penetration test of the military's armor-breaking warhead and meet the requirements of the most stringent conditions; Meet the static explosion test, burning and baking test, explosion pressure test, resistivity test and so on
Easier installation and maintenance
Barrier explosion-proof materials can be quickly installed by mechanized method, quickly removed by mechanized method, and quickly cleaned by mechanized method;

Main products and features

Isolation material characteristics

It can protect the storage and transportation of flammable and explosive liquid and gaseous dangerous chemicals, and effectively prevent the explosion of gasoline, diesel, chemicals and other substances in accidental circumstances.
The barrier effect is remarkable, reducing the combustion speed and flame propagation speed in the oil tank, and contributing to the fire extinguishing operation.
Effectively inhibit surges, reduce liquid sloshing energy, and reduce the risk of accidents caused by surges during transportation.
Eliminate the risk of static electricity, avoid static accumulation and discharge sparks during oil loading and unloading.
Prevent BLEVE phenomenon, ensure the safety of storage and transportation.

Energy saving and emission reduction, effectively inhibit oil and gas volatilization, reduce oil consumption, reduce environmental pollution.

Compatibility to Fuel

Abstract of test report issued byChinese People's Liberation Army Oil and Oil Equipment Test Center

Oil sample: No.90 car gasoline, No.-10 military diesel, No.3 jet fuel
Container: Metal can with epoxy resin printing in the wall, 4L
Conditions: Running test by 5000km, four weeks of accelerated storage test under 43'c
Test result:
- AMPUTE doesn't affect oil combustion property.

- AMPUTE doesn't affect oil low temperature property.

- AMPUTE slightly affects the oil invariability of long time storage, but it is not obvious.

- There is no effect on the generation of active sulfur in oil, namely installing AMPUTE explosion prevention system doesn't change copper sheet corrosion rate.

- There is not any change on the surface of AMPUTE and there is no fractured and womnmaterial in the metal can.

Cleaning of Storage Tank with AMPUTE

Extensive testing has been performed over the last decadeby AMPUTE, we have developed an abluent made of specialformulation and washing process to realize “easy clean andeasy maintenance". AMPUTE abluent is eco friendly,pollution-free to oil and corrosion-free to AMPUTE materials.

Cleaning the storage tank by using AMPUTE abluent couldprevent combustion, explosion and “three wastes".
