The seamless steel pipe is used as the column material, the wind load coefficient is small, the wind resistance is strong, the tower column is connected by the outer flange, the bolt is pulled, it is not easy to be destroyed, the maintenance cost is reduced, the tower is arranged in a triangle shape, and the steel is kept small and small. It has a small footprint, saves land resources, and is convenient for site selection. The new three-leaf type cutting board foundation reduces the basic cost truss structure design, and the transportation and installation are convenient. The short construction period of the construction period is designed with the wind load curve. The lines are smooth, and it is not easy to collapse in case of rare wind disasters. The design of reducing human and livestock casualties conforms to the national steel structure design specifications and tower design rules, and the structure is safe and reliable.
The main material (tower leg) of the steel pipe tower can be a seamless steel pipe or a high-frequency welded pipe. Other horizontal and oblique materials can be angle steel or steel. The specific model and size require the designer to be based on construction conditions and operating environment.
In the production of steel pipe towers, in order to ensure the replaceability of each welded component in mass production, it is generally necessary to produce a production mold, which must be precise, in order to ensure that the mass production does not cause problems and achieve replacement.

(The above parameters are only examples, and the design parameters of the towers in different environments are different).
