After a busy week, I had a nice and relaxing weekend with my friends. We walked into the mall, and as we went shopping, I suddenly thought about how the mall was built. What materials do we need to build a shopping center? We need cement and steel pipes (ERW steel pipe to other types). When I looked up and saw the sprinkler on the ceiling of the shop, I realized that the steel pipe was everywhere.

Because of steel pipes, we can be safe in the event of fire in the mall. Because of steel pipes, we got water and natural gas, so we can cook the meal and take a bath. I can’t imagine what our life would be like if there were no steel pipes in the world. If there were no steel pipes in the world, we wouldn't be able to cook, and there would be no tall buildings in the city. If there were no steel pipes in the world, how would we transport oil and gas? I have no idea. All I know is that we should thank the pipeline for carrying water and natural gas for us, but also for the contribution of the steel pipe to the house we live in. I think that we can't live in a world without steel pipes.
