How Often To Replace Natural Gas Pipes

There are three types of natural gas pipes: hoses, aluminum-plastic pipes, and metal bellows. The hose is relatively easy to age, leak, etc., and needs to be replaced after 18 months of use. Compared with the aluminum-plastic pipe, the service life is relatively long. If there is no damage, it can be used for a long time, but the interface should be checked regularly. Metal bellows can be replaced for about 6 to 8 years.
