Factory is a very important facility in a city. Factories produce materials for the construction of cities and sometimes ship them to other cities or export them. There are many different types of factories, some making building materials, some making daily necessities, and even some processing food. This week we focused on factories that deal with building materials and learned how the assembly lines that make steel pipes work.

After the observation of the production line and interview with the workers, we got to know the production process of the steel pipe. Firstly, they transport this kind of rolls of steel from a steel mill in Shanghai.

Then the steel plate is then squeezed by rolls of different sizes to bend into a round tube as it moves through the tracks.

Next, the steel pipe being bent into a round tube passes through an electric welding shop, where the edges of the steel plates are welded together.

After being welded, the steel pipe is shaped again, and the surface of the steel pipe is polished here.

Finally, at the end of the production line is a chainsaw that splits the entire steel pipe into shorter, identical pipes. The tubes are then loaded into bundles and transported to the construction site.

From the interview, we knew that the steel pipe produced by this factory would be transported to Jiangsu Province, Anhui Province, and Jiangxi Province. The raw material is from Shanghai Baosteel Group, which is China's largest steel factory.
