A line pipe is basically a long tube used to move liquids or gases from one place to another, kind of like a super long straw! These pipes are usually made of metal, and they’re essential for transporting all sorts of stuff over really long distances. Most of the time, they’re carrying things like oil, gas, or water, but sometimes they’re used for other stuff too, like moving coal or iron ore mixed with mud. It’s like a big highway system for liquids and gases, helping them get where they need to go efficiently and safely. So, the next time you turn on your gas stove or fill up your car with fuel, remember that it’s thanks to these trusty line pipes doing their job behind the scenes!
