product feature

Feature 1:The fire did not explode

After the composite LPG cylinder is placed in the fire, the inner tank softens, but the composite material retains its strength. LPG slowly and controllable leaks through the composite material gap, forming a flame on the cylinder surface. During the whole combustion process, the flame is controllable and the cylinder does not explode.

Feature 2:Corrosion resistance and aging resistance

The materials used in composite LPG cylinders have been specially modified, with excellent corrosion resistance and aging resistance. The products are as new as ever. Especially for coastal areas, they are not only safer and more reliable, but also have a lower comprehensive cost than steel cylinders.

Feature 3:Lighter Weight

One of the most notable features of composite LPG cylinders is their light weight, which is only 50% of that of steel cylinder of the same volume.This feature gives the product better portability, which not only effectively improves the end-user experience, but also reduces the delivery cost.

Feature 4:High Strength

The hydraulic burst pressure of the composite LPG cylinder is about 1.9 times that of the steel cylinder. When the cylinder is full and the shell is 1.2 meters high, it can drop 10 times in 5 angles, and the cylinder strength is not affected.When the full cylinder is impacted at a height of 3 meters without shell, the residual strength of the cylinder is not less than 3.65 times the safety factor.

Feature 5:Long life, no mandatory periodic inspection requirements, low comprehensive cost

The actual service life of composite LPG cylinder in foreign countries is more than 20 years.Domestic standards allow for 12 years of use without periodic inspections.


1. Q: Is the production and sale of composite LPG cylinders permitted by national laws and regulations?

A: Yes, the Special Equipment Supervision Bureau of the State Administration for Market Regulation has allowed and encouraged enterprises to produce and sell composite LPG cylinders since 2016. At present, relevant group standards have been put on record, and our company has obtained the production license.

2. Q: Do composite LPG cylinders meet the working conditions of steel cylinders?

A: Yes, the composite LPG cylinder can be used in high and low temperature, high humidity, outdoor ultraviolet, coastal corrosion, etc.

3. Q: How does the service life and periodic inspection of composite LPG cylinders differ from that of steel cylinders?

A: According to the requirements of the group standard, the service life of composite LPG cylinders is 12 years. If the life of the valve permits, no periodic inspection is required during this period.If the life of the valve is not allowed, the enterprise can replace the valve by itself or entrust Athird party to replace the valve according to the requirements of our company's valve replacement specification and Appendix A of the group standard.

4. Q: Are existing steel cylinder valves, charging guns, and distribution suitable for composite LPG cylinders?

A: The valve used for composite LPG cylinders differs only from the steel cylinder valve in the inlet thread, the rest of which is the same as the steel cylinder valve.

The existing steel cylinder gas charging gun is also suitable for composite LPG cylinders, and the up-down charging gun is more suitable.

Composite LPG cylinders can be stacked up to four or more layers with stable stacking, suitable for existing distribution habits.

5. Q: Is it easy to scratch the product when the product is hollow out? Is there a safety hazard when the gas cylinder is scratched?

A : Composite LPG cylinder hollowing is a common design pattern abroad, after more than 20 years of use, practice has proved stable and reliable.Hollowing can make the gas cylinder LPG gas liquid conversion and the outside world to better heat exchange, improve the efficiency of vaporization.Gas cylinder scratches are strictly tested in the group standard. Daily scratches and scratches do not affect product safety.Serious scratches (such as scratch depth more than 2mm) should be isolated for inspection and treated according to Appendix A of the group logo.
