A question we get asked all the time here at Shevic Energy is: “How long does a gas cylinder last?”
It seems like a simple question, doesn’t it? A quick Google search might give you an answer in years, but the truth is a little more complex and, frankly, much more important for your safety.
The lifespan of a gas cylinder isn’t just about how long the metal can hold up. It’s about a journey of professional care, inspection, and certification. It’s a journey that ensures every single cylinder in our care is in top condition and certified for your safety, from our depot to your home in Pretoria. We want to take a moment to clear up a few common misconceptions and walk you through what really determines the longevity of your gas bottle.
The Misconception of a Simple “Lifespan”
It’s easy to think of a gas cylinder like a carton of milk with a clear expiration date. But the reality is far from it. LP gas cylinders are robust pressure vessels, designed and manufactured to rigorous international standards (like SANS 1825 in South Africa) to be incredibly durable. Made from high-quality steel, a well-maintained cylinder can last for decades, often exceeding 30 to 40 years of service.
So, why does the question still cause confusion? The misconception arises because the physical longevity of the bottle itself is not the same as its certified service life. A cylinder’s true longevity is not measured by its age but by its ongoing compliance with strict safety regulations, and this is where the professional inspection and re-certification process becomes the most critical part of its life cycle.
Think of it like a vehicle’s roadworthy certificate. A car can be 20 years old and still be perfectly safe to drive, provided it undergoes regular maintenance and passes a new inspection every few years. Your gas cylinder works in a very similar way. The shell is built to endure, but it’s the professional stamp of approval, the equivalent of a roadworthy certificate, that truly matters for your safety.
The South African Standard: SABS Inspections and Re-certification
In South Africa, the SABS gas inspection process is the cornerstone of gas cylinder safety. All cylinders, regardless of their size, must be periodically inspected and re-certified by a SABS-approved inspection body. This isn’t a suggestion; it’s a legal and safety requirement. For most cylinders, this inspection cycle is every 10 years.
What does a professional inspection entail? It’s a comprehensive check-up that includes a visual and physical examination of the cylinder’s exterior and interior. Inspectors look for:
- Corrosion and Rust: They check for any signs of rust or significant corrosion that could compromise the cylinder’s structural integrity.
- Dents and Damage: They inspect for any dents, bulges, or other physical damage from being dropped or mishandled.
- Valve and Collar Integrity: The valves, pressure relief devices, and collars are all checked for proper function and to ensure they are free of leaks and damage.
- Hydrostatic Pressure Testing: In some cases, a hydrostatic test may be performed, where the cylinder is filled with water and pressurised to check for any leaks or weaknesses under extreme stress.
Once a cylinder successfully passes this rigorous inspection, it is stamped with a new date, certifying its safety for another period of use. This stamp is the official “proof” that the cylinder is fit for purpose. It is this stamp, not the original manufacturing date, that you should look for when you receive your next gas delivery.
A Visual Guide to Your Cylinder’s “Passport”
Every gas cylinder has a series of stamps and markings on its collar or body that serve as its “passport.” These stamps tell a story of its manufacturing and its journey through professional inspections. Here’s what you might find:
- Manufacturer Stamp: The logo or name of the company that manufactured the cylinder.
- Serial Number: A unique identification number for the cylinder.
- Manufacturing Date: This is the original date the cylinder was created. It’s often in a month/year format (e.g., 04/20).
- SABS Re-certification Date: This is the most important date for you to know! It shows the last date the cylinder was professionally inspected and approved. This date determines whether the cylinder is currently valid for use.
At Shevic Energy, we handle all of this for you. We take the empty cylinders you give us and send them to be professionally re-certified. Then, we deliver a fresh, full, and certified cylinder right to your door. This seamless process means you never have to worry about whether your cylinder is compliant or safe.

Beyond the Bottle: The Importance of a Full System Check
While the cylinder is a key component, its safety is part of a larger system. To ensure complete gas safety Pretoria residents should also pay close attention to the other parts of their gas setup.
- Regulators and Hoses: These flexible parts are the bridge between your cylinder and your appliance. They have a limited lifespan and must be SABS-approved. Hoses, in particular, have an expiry date, usually stamped on the rubber, and should be replaced every 5 years. A simple visual inspection for cracks and wear is a great habit to get into.
- Professional Installation: For any fixed gas installation (like a gas stove or water heater), you must have a valid Certificate of Conformity (COC). This is a legal requirement and is often a prerequisite for insurance claims. It’s issued by a registered gas installer who confirms that your entire system is compliant with South African safety standards.
We encourage you to think about your gas usage holistically. A safe cylinder in a poorly maintained system is still a risk. By combining a reliable cylinder from a trusted supplier with a well-maintained and professionally installed system, you create the safest possible environment for your family.
Frequently Asked Questions
Based on common questions from gas users in Gauteng and Pretoria, here are some quick answers to a few key topics:
Q: Why does my gas finish so quickly? Could it be a leak?
A: It’s important to first rule out a leak. Do a simple soap test on the regulator and hose connections. If you don’t see bubbles, the most likely reasons for fast consumption are a faulty regulator, an old or inefficient appliance, or a change in usage, such as more frequent cooking or using the gas for a new purpose. Cold weather also affects gas pressure, making it seem to run out faster.
Q: How do I know how much gas is left in my cylinder?
A: You can use the warm water test. Pour warm (not boiling) water down the side of the cylinder. The gas inside keeps the cylinder cool, so a line of condensation or coldness will appear on the outside, marking the level of the liquid gas.
Q: Can I store a gas cylinder inside my home?
A: Yes, you can. According to South African National Standards (SANS 10087-1), you can store a 9kg gas cylinder inside a dwelling, but it must be in a well-ventilated area, at least 1m away from any doors and windows. Fixed installations must be in a dedicated cupboard with proper ventilation and away from electrical points.
Q: What do I do if I smell a gas leak?
A: Immediately turn off the gas at the cylinder valve. Open all windows and doors to ventilate the area. Do not operate any electrical switches, light any matches, or use your phone. If the smell persists, evacuate the property and contact a certified gas installer or the fire department from a safe location.
So, to answer the question: how long does a gas bottle last? The answer is “a very, very long time,” but only if it’s treated with the professional care it deserves. The certified longevity, proven by regular inspections and re-certification, is the true measure of a cylinder’s safety.
