Service life of hoses connecting gas stoves under weather conditions.

Natural gas hoses should be replaced once a year. Replacing the hose once a year can ensure the flexibility of the hose and avoid gas accidents caused by the aging and falling off of the hose. The length of natural gas hose should not exceed 2m, and the hose should not pass through walls or doors and windows. After using gas, be sure to close the valves on the pipeline (valves with double forks or single nozzles) to avoid accidents. Under normal circumstances, natural gas pipelines are replaced every 2-3 years.
