The versatile applications of steel pipes in structures.

2015-02-11


   What are the applications of steel pipes in structures? Structural steel pipes, including various welded and seamless pipes, have an ideal circular cross-section, which gives them a strong ability to resist local buckling. They are the best lightweight components for bearing radial internal and external pressures. Steel pipes can be used to make basic elements such as columns and beams, which can be used individually in structures or combined into various structural types like frames, trusses, and grids. In steel-concrete composite structures, concrete-filled steel tubes are being promoted as an effective new application of steel pipes.
  They are very popular for use in grid structures. The long-standing hollow ball joints or bolt ball joint grid structures use steel pipes as members, which is the best choice. They are also very common in tall structures; steel pipes not only have superior cross-sectional performance but their curved outer surface can significantly reduce wind load effects. Using steel pipe masts or towers allows these advantages to be fully realized.
