How important is the use of steel pipes in daily life?

Steel pipes have a wide range of applications. For example, in engineering fields such as natural gas pipelines, oil companies, chemical companies, power pipelines, thermal pipelines, water supply and drainage pipelines, steam heating, pressure steel pipes for hydropower stations, thermal power generation, long-distance transmission pipelines for water sources, pile driving, bridges, steel structures, etc.

Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel material. Using steel pipes to manufacture building structural grids, pillars, and mechanical supports can reduce weight, save metal by 20-40%, and achieve factory mechanized construction. Due to the use of steel pipe truss structure in the processing workshop, steel is actually saved by 42.9%. Using steel pipes to manufacture highway bridges not only saves steel and simplifies construction, but also greatly reduces the area of protective coating, saving investment and maintenance costs. So, no other type of steel can completely replace steel pipes, but steel pipes can replace some profiles and bars. Steel pipes have a significant impact on the development of the national economy and the improvement of human quality of life, far surpassing other types of steel. From people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to the manufacturing of various agricultural machinery, the development of underground resources, and the use of guns, bullets, missiles, rockets, etc. in national defense and aerospace, steel pipes are indispensable.

A pipeline widely used for transporting fluids, such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when their bending and torsional strength is the same. They are an economical cross-sectional steel material widely used in the manufacture of structural and mechanical parts, such as oil drill rods, automotive transmission shafts, bicycle frames, and steel scaffolding used in construction
