Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is a steel tube tower, which is a lattice tower whose main components use steel tubes and whose other components use steel tubes or section steel, with a single-piece weight of about 10000 kg, mainly composed of angle steel, steel plate and flanges, gusset plates, bolts, etc., made through processes such as main material blanking, accessory processing, conical tube rounding, riveting and welding assembly, and welding. The key upstream raw materials of this product are angle steel, steel plate and accessories such as bolts, flanges and gusset plates, and downstream it is mainly applied in the support of overhead transmission lines, especially in large-crossing structures and urban grid tower structures. In terms of system boundary, infrastructure such as the manufacture of production equipment and the construction of plant buildings 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 electricity and other energy are calculated using the Chinese average energy structure.
Activity Description
The system boundary is the steel pipe tower from cradle-to-gate, starting with the input of raw materials and ending with the finished steel pipe tower leaving the factory. The main stages include main material cutting (angle steel, steel plate, etc.), accessory processing (bolts, etc.), forming circular conical tubes, riveting and welding assembly.
Process Description
Steel pipe tower refers to a lattice tower composed of steel pipes for main components and steel pipes or steel for other components. It is a supporting structure for overhead transmission lines to support conductors and lightning protection wires, so that the conductors meet the distance requirements from the ground and ground objects, and can withstand the load of the conductors, lightning protection wires and themselves and external loads. The steel tube tower is mainly composed of steel pipes, steel sections, flanges, node plates, bolts and other accessories. It has large cross-sectional stiffness, good cross-sectional stress characteristics, simple stress, and beautiful appearance. It is a tower-like lattice steel structure and is widely used in large-span structures and urban power grid tower structures to support overhead transmission lines.

Technology comment
The production of steel pipe towers mainly includes processes such as main material cutting, accessory processing, tapered tube fabrication, riveting and welding assembly. After the main material steel plate is cut and rolled into a tapered tube, it is welded and assembled with flanges, gusset plates and other accessories to form a tower section. The tower section leaves the factory after passing the final inspection.
