Abstract With the increase in the global demand for ductile iron pipes, understanding regional standards for dimensions and models is crucial. This article explores the AWWA C - 151 (North America), ISO 2531 (Europe), and AS/NZS 2280 (Australia & New Zealand) standards. By comparing common dimensions, outer diameters, and wall thicknesses (including K9 and PN20 grades), it reveals key differences and their origins, offering valuable insights for relevant industries. 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. 2. North American Ductile Iron Pipe Dimensions and Models 2.1 Standard Overview North America predominantly adheres to the AWWA C - 151 Standard. This standard is tailored to the region's engineering needs and technical capabilities, ensuring the safe and reliable operation of ductile iron pipes under diverse working conditions. 2.2 Dimension Details The following table presents some common nominal dimensions (in inches), outer diameters, and wall thicknesses (for partial pressure ratings) as per the AWWA C - 151 Standard: Nominal Dimension (inches) Outer Diameter (inches) Wall Thickness (inches) 3 3.96 0.25 4 4.8 0.26 6 6.9 0.25 8 9.05 0.27 10 11.1 0.29 12 13.2 0.31 3.
