Small Diameter: Starting from around 16 inches (406.4 mm) and going up to larger sizes, such as 48 inches (1219.2 mm).

Large Diameter: LSAW pipes are commonly manufactured in larger diameters, such as 60 inches (1524 mm), 72 inches (1828.8 mm), or even larger sizes based on project requirements.

2. Wall Thickness: The wall thickness of LSAW steel pipes can also vary depending on the intended application and industry standards. LSAW pipes are available in a range of wall thicknesses to meet specific project requirements. Typical wall thicknesses for LSAW pipes may range from a few millimeters to several inches, depending on the diameter and intended use of the pipe.

3. Length: LSAW steel pipes are typically manufactured in standard lengths to facilitate handling, transportation, and installation. Common lengths for LSAW pipes can range from 6 meters to 18 meters, with the possibility of custom lengths based on project specifications.

4. Standard Specifications: LSAW steel pipes are manufactured to meet various international standards and specifications, such as API 5L (for oil and gas pipelines), ASTM A252 (for piling), ASTM A53 (for structural applications), and others. These standards define the size range, dimensions, tolerances, and other requirements for LSAW pipes to ensure quality and performance.

It's important to note that the size range of LSAW steel pipes can be customized based on specific project requirements and industry standards. Manufacturers have the capability to produce LSAW pipes in different sizes and specifications to meet the needs of a wide range of applications in industries such as oil and gas, construction, water transportation, and more.
