There is no specific period for changing the gas pipe. If the gas pipe is adequately maintained and cleaned at regular intervals, it can last up to 5-6 years. A gas pipe made with high-quality material may even last up to 10-12 years, depending on your care. However, the time varies in various situations. If you notice any dysfunctionality or breakage in the pipeline, you must immediately call a professional technician and get it repaired or replaced.
