Amid rising tensions in the Middle East and concerns over fuel supply, many Indian households are turning more towards LPG cylinders. This is also turning to PNG connections. At this time, a major question has arisen: do LPG cylinders and PNG gas really have an expiry date?
The expiry date, as often referred to in LPG cylinders, is actually a mandatory testing period. This ensures that the cylinder is safe for continued use. After this date, the cylinder needs to be tested and certified before being reused.
On the ring at the top of the LPG cylinder, you will find an alphanumeric code such as A26, B25, or C27. This code tells you when the cylinder is due for testing. The letter represents the quarter of the year, and the number represents the year. For example, A for January-March, B for April-June, C for July-September, and D for October-December.
Using a cylinder after the test date can be dangerous. Over time, pressure and exposure to the external environment can weaken the cylinder.
Unlike LPG, PNG is supplied continuously through pipelines. Therefore, the gas has no expiration date. As long as the supply system is functioning properly, the gas is safe to use.
However, rubber hoses and pipeline components have a limited shelf life, usually 18 to 24 months. Over time, these hoses can crack or leak, requiring regular replacement.
Using the BIS Care app, you can check the manufacturing and expiration date of a gas hose. By entering the CML number printed on the hose, you can get complete safety information, including its validity.
