Aluminum Pipe Tube Size Chart

Aluminum pipes and tubes are defined by their Nominal Pipe Size (NPS) and a non-dimensional number indicating wall thickness, called the Schedule (SCH). The most common schedules for aluminum pipes are SCH40 and SCH80, representing standard and heavy wall thicknesses, respectively.

These pipes are widely used across industries for structural frames, machinery components, bus pipes, marine piping, railings, cylinders, and conductive tubes. This page provides a complete reference for aluminum pipe sizes, schedule dimensions, and wall thickness to help engineers and designers select the correct pipe for their projects.

Aluminum Pipe Standard Sizes (NPS Pipe Size System)

Aluminum pipes are defined by their Nominal Pipe Size (NPS), which is a standard system indicating the pipe's approximate diameter. The NPS determines the pipe's outer diameter (OD), while the wall thickness is determined separately by the schedule number (SCH).

The table below provides a reference for the most common NPS sizes and their corresponding outer diameters in both millimeters and inches.

Aluminum Pipe Schedule Chart (SCH10 / SCH40 / SCH80)

The schedule number (SCH) defines the wall thickness of a pipe while the outer diameter is determined by the NPS. Common schedules for aluminum pipes include:

SCH40 Aluminum Pipe Dimensions

SCH40 is the most commonly used pipe schedule for aluminum tubes, representing a moderate wall thickness suitable for general industrial applications and medium-pressure piping systems.

SCH80 Aluminum Pipe Dimensions

SCH80 represents a thicker wall for aluminum pipes, suitable for high-pressure or load-bearing applications, including pipelines and specialized industrial equipment piping systems.

Aluminum Pipe Weight Chart

The following table provides approximate weight per foot for aluminum pipes in SCH40 and SCH80 schedules. Engineers can reference this for design calculations and material selection.

If you need additional aluminum pipe sizes, custom tube dimensions or project-specific specifications, our engineering team can help evaluate the most suitable SCH40 or SCH80 pipe options.
