I need some articles on underground pipelines
Answer
I suggest you start with our Databases by Subject webpage (link below). Business & Industry, Government & Law or Science are all possible types of databases. Select one of them to begin your search. For this I would recommend the Advanced Search.
I would suggest that all of your searches include the word pipelines. Then select a second term, e.g. public awareness; neighborhoods; legislation.
As you are reviewing articles, note the subject headings and the words in the abstract or article to find other words that define what you are interested in.

All these question are answered by real COM Library staff, so we can only answer if we're open.
