Steel pipes serve as framework columns and beams in high-rises. Their high strength ensures building stability. For example, in a 30-story building, a large amount of steel pipes form a reliable structure.
In the oil and gas field, steel pipes transport crude oil and gas over long distances under high pressure. A long-distance pipeline may consist of numerous steel pipes.
For bridges and tunnels, steel pipes act as structural supports or decorative railings, enhancing safety and aesthetics.
Steel pipes are used for large-diameter water supply and sewage pipes in urban systems, preventing leakage.
