A polymer composite gas cylinder is a vessel designed for the storage and safe use of liquefied petroleum gas (LPG). It is made of fiberglass reinforced polymer material.

Advantages of polymer-composite gas cylinders:

• Lightweight:  Polymer composite cylinders are significantly lighter than metal cylinders, making them easier to transport and use.
• Durable:  Polymer composite cylinders are very durable and can withstand high pressure.
• Safe:  Polymer composite cylinders do not explode in a fire.
• Not subject to corrosion:  Polymer composite cylinders are not subject to corrosion, which increases their service life.
• Transparent:  Polymer composite cylinders are translucent, making it easy to determine the gas level.

Disadvantages of polymer-composite gas cylinders:

• Expensive:  Polymer composite cylinders are more expensive than metal cylinders.
• Not suitable for high temperatures:  Polymer composite cylinders are not suitable for use in high temperatures.
• Cannot be repaired:  Polymer composite cylinders cannot be repaired.

Use of polymer-composite gas cylinders:

• Storage:  Polymer composite cylinders should be stored in a cool, dry place, away from heat sources.
• Transportation:  When transporting polymer-composite cylinders, care must be taken.
• Use:  Polymer composite cylinders should be used in accordance with the manufacturer's instructions.
