Dimensions and Sizes Schedule

The pipes conform to the Nominal Dimension standard ASME B36.10M, which specifies the nominal pipe size (NPS) or outside diameter and the schedule number indicating the average wall thickness.

However, certain pipe sizes may not be available under the ASTM A333 standard due to the impact of heavier wall thickness on material properties. Clients with specific requirements should adhere to supplementary specifications provided in ASTM A333.

This ensures that the pipes meet the necessary standards while accommodating variations in wall thickness that can affect performance characteristics.

Related Standards for Producing ASTM A333 Grade 6 Pipe
