Description
The product represented by this dataset is a steel-tube pole, namely a transmission steel-tube structure composed of single or multiple steel-tube members rigidly connected, with a single-piece weight of about 4000 kg, mainly composed of steel plates, round steel, flanges and welding materials, etc., manufactured through processes such as machining, welding and inspection. The key upstream raw materials of this product are steel plates, round steel, steel and flanges, welding materials, etc., and the downstream is mainly applied to fields such as power, communication, municipal works and construction, used to form the structures of power facilities and other support and transmission structures. As for the system boundary, infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources, and energy such as electricity is calculated using China's average energy mix.
Activity Description
The system boundary is the steel pipe pole cradle-to-gate, with the starting point being the input of raw materials and the end point being the finished steel pipe pole leaving the factory. The main stages include processing (steel plates, round bars, steel products, etc.), welding (flanges, welding materials, etc.) and inspection.
Process Description
Steel pipe pole refers to a transmission steel pipe structure whose main pole is composed of single or multiple steel pipe members rigidly connected. It is mainly made of steel plates, round steel and other steel materials, flanges, welding materials, etc., which are processed and welded. The hollow tubular structure has the properties of light weight, high strength, wind pressure resistance, corrosion resistance (hot-dip galvanizing) and other properties. It is in the form of a rod-shaped or tower-shaped steel structure. It is widely used in facility support and transmission structures in the fields of electric power, communications, municipal administration, and construction.

Technology comment
The production of steel pipe poles mainly includes processing, welding, and inspection. Using high-quality steel plates as raw materials, finished steel pipe poles are produced through processes such as blanking, rolling, longitudinal seam welding, rounding, circumferential seam welding, flange or plug end welding, hot-dip galvanizing for corrosion protection, and straightening and inspection.
