What Makes Composite LPG Gas Cylinders Safer Than Steel?

We live in a world of exciting innovation. Industries are always looking for ways to improve safety, convenience and price point and the Liquified Petroleum Gas and gas cylinder business is no different. Using composite pressure vessels (CPVs) to store and dispense gas instead of steel cylinders, you can benefit from improved safety, efficiency and convenience.

Let’s find out why.

What Is A Composite Gas Cylinder?

Composite materials have an excellent potential for fabrication with remarkable mechanical properties, especially in terms of weight, strength, damage tolerance, and energy absorption capabilities.

The technique used to create the composite pressure vessel is called filament winding.  Composite pressure vessels were initially created for aerospace applications. Today this space age technology has found a practical use in water treatment stations and the petroleum industry. 

A composite cylinder is a three-layer cylinder comprising:

  • An outer HDPE jacket
  • A polymer-wrapped fibreglass composite layer 
  • A blow-moulded High-Density Poly Ethylene (HDPE) inner liner

The Benefits Of Composite Cylinders 

Composite pressure vessels are lightweight and safe, and when used as LPG cylinders, they have the following features/benefits:

  • Lightweight, with maximum weights of 5 kg, 10 kg and 14 kg.
  • They feature a translucent body that helps users to monitor the LPG gas level accurately and arrange their following refill in advance. 
  • They do not rust or corrode, reducing the likelihood of leaving stains on surfaces. 
  • The new and elegant design is far more visually appealing and suited for today’s modern kitchens and does not require repainting.

And the most significant benefit? Composite cylinders are 100% explosion-proof! LPG gas is a cost-effective, environmentally friendly, and reliable alternative to electricity. But the unfortunate reality is that LPG gas is a highly volatile and flammable material stored within a highly pressurised environment.

Safety Guarantee 

Once a gas leakage occurs, an open flame or ignition source can result in a devastating and even fatal explosion. Similarly, if a gas cylinder is dropped or penetrated, the high-pressure environment inside can also cause an explosion. This increases the danger associated with the transportation and storage of gas cylinders. 

However, the composite gas cylinder design displays the following properties:

  • Better energy absorption: This is because of the layered design (stratification) of the laminate materials that make up the composite cylinder, allowing gas to seep out gradually rather than explode.
  • Stable storage conditions: Steel gas cylinders are far more susceptible to extreme temperatures than plastic composite cylinders are. Metal is an excellent conductor of heat, meaning a plastic composite cylinder offers a far more stable environment for gas storage.
  • Lightweight design: Composite cylinders are up to 50% lighter than their steel counterparts, making transportation, handling and storage far more safe and convenient.
