Do you know LPG cylinders have an expiry date? Well, the technical term as the LPG companies in India say, is the resetting date which many consumers call the expiry date. If you are unaware of the cylinder’s expiry date then you have landed on the right spot as we will discuss it in detail.
Cylinders are made of composite material and steel. According to the standards approved by the Chief Controller Of Explosive(CCOE) the cylinders should be made of special steel with a protective coating.
The manufacturing of the LPG cylinders includes raw materials like carbon fiber and reinforced polymer. These materials make the cylinder lighter in weight and enhance its tensile strength.
The reinforced cylinder contains carbon fiber as per the PESO circular No. R.4(2) 100/2007 dated 20.08.2007 all the cylinders required to be taken to the first Statutory Testing and Painting after 10 years and it must be followed by every 5 years.
The resetting date of the cylinder is marked on the side of the vertical stays of the cylinder. The marking indicates the resetting date of the cylinder. The date is written in the form of the alphabet and the year of the testing.

So, for instance, if your cylinder is marked A-28, then it would mean the resetting date for your cylinder is between January to March in the year 2028.
While collecting the cylinder from the distributor you must check the resetting date as a safety precaution. You can also ask your delivery person to check the resetting date on the cylinder.
The cylinders which have passed the due date are transported to the bottling center. In the bottling center, the LPG gas cylinder is tested to check its durability. Some of the common tests which are performed on the cylinder for quality checking are hydrostatic tests, burst tests, ultimate tensile strength tests, impact tests, and pressure cycling tests.
Once the tests are done the resetting date of the cylinders is marked by the LPG companies on the bottling center where these cylinders are segregated.
For the LPG cylinders which are for the due date, proper care is taken from the distributors to ensure the resetting date bottles do not end up in the market. The norms and standards set by the government are followed while refilling the cylinders. Each cylinder is visually tested for defects and then Statutory Testing and Painting are done.
An LPG cylinder has a lifespan of 15 years and in between this time, it is mandatory to be checked twice. In the hydro test, the cylinder is filled with water for testing and in the pneumatic test 5 times, the pressure at which LPG is stored is applied to test the quality of the cylinder. If the cylinders fail in any, it is discarded to be filled again, and this ends up a scrape.
