Core Viewpoint - This year is critical for the renovation and replacement of aging underground gas pipelines in Shanghai, with over 1,000 kilometers of pipelines expected to be updated, all of which are located within community internal streets [1] Group 1: Pipeline Renovation - The renovation project will primarily affect community roads and parking areas due to the location of the neighborhood pipelines [1] - Aging pipelines in older communities have typically been in service for nearly 30 years, with materials such as gray cast iron pipes approaching their usage limits, posing safety risks like gas leaks if not updated [1] - The new gas pipelines being installed will use PE material, which theoretically has a lifespan of up to 50 years [1]
