1. Introduction
The global demand for ductile iron pipes is on the rise, making it essential to understand the standards of dimensions and models across different regions. These pipes, valued for their high strength, toughness, and corrosion resistance, are widely used in infrastructure projects such as water supply, drainage, and gas transmission. However, due to variations in engineering requirements, technical norms, and historical - cultural backgrounds, there are significant differences in their dimensional and model standards. These disparities impact not only production and manufacturing but also procurement, design, and installation. Thus, in - depth research on these regional standards is vital for the growth of related industries in the global market.
