Industrial tourism, also known as factory tourism or industrial heritage tourism, refers to the practice of visiting and learning about the history, culture, and operation of industries, factories, and other types of manufacturing and production facipties. In Engpsh, you can describe this as "industrial tourism" or "factory tourism." For example, you could say:

"I'm interested in industrial tourism. Do you know of any factories or industrial sites that offer tours?"
"I went on an industrial tourism tour last weekend. It was really interesting to see how the factory operated and to learn about its history."
"Industrial tourism is a great way to learn about the history and culture of a region. Have you ever been on an industrial tourism tour?"

I hope this helps! Let me know if you have any other questions.
