What is the function of steel pipe

Steel pipe is a type of steel with a hollow section whose length is usually much greater than its diameter or circumference. They can be divided into round, square, rectangular and special-shaped according to the cross-sectional shape; according to the material, they can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the use, they can be divided into: For engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. In addition, steel pipes can also be divided into seamless steel pipes and welded steel pipes according to the production process. Seamless steel pipes are divided into hot-rolled and cold-rolled (drawn), while welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes. 

Steel pipes have a wide range of functions. They are not only used to transport fluids and powdery solids, but also to exchange heat energy and manufacture mechanical parts and containers. In the construction field, steel pipes can be used to manufacture structural grids, pillars and mechanical supports, which can reduce weight, save 20 to 40% of metal, and achieve factory-like mechanized construction. In bridge construction, the use of steel pipes can save steel, simplify construction, and reduce the area of protective coating, thereby saving investment and maintenance costs.

Steel pipes are one of the preferred materials in construction and engineering due to their exceptional strength, durability and adaptability. The high strength of steel enables it to withstand large external loads and pressures, ensuring stable operation of the project. At the same time, steel is not easily affected by corrosion and oxidation, has a long service life, reduces the frequency of maintenance and replacement, and reduces operating costs. The plasticity and processability of steel allow it to be processed and customized in various shapes and specifications according to engineering needs, adapting to different engineering environments and conditions. In addition, the recyclability of steel makes it consistent with the concepts and requirements of sustainable development, reducing resource consumption and environmental pollution.

Large-diameter steel pipes have strong transportation capabilities in application and are often used in oil and gas transportation, urban water supply, infrastructure construction, marine engineering and other fields. They can withstand high pressure and temperature, ensure the safe transportation of energy, and effectively transport large amounts of water to ensure daily water needs. In infrastructure construction, large-diameter steel pipes serve as supporting, fixing or drainage elements, capable of withstanding huge pressure and weight, providing stability and safety. In marine engineering, large-diameter steel pipes can maintain stable working conditions for a long time in the marine environment due to their corrosion resistance and high pressure resistance, providing reliable guarantee for the development and utilization of marine resources.
