Understanding 24 Inch Schedule 20 Pipe
24 inch Schedule 20 pipe is a standard steel pipe size used as a reference in utility systems, plant design, water lines, process piping studies, and CAD drafting. With an outside diameter of 610 mm and a wall thickness of 9.53 mm, this pipe size is useful where large flow capacity is needed while keeping the wall thinner than heavier schedules.
What Does Schedule 20 Mean?
Schedule 20 refers to the wall thickness series of the pipe. For NPS 24, Schedule 20 gives a wall thickness of 9.53 mm. The schedule affects the inside diameter, total weight, fabrication requirements, and compatibility with fittings, supports, and layout clearances.
Why These Pipe Dimensions Matter
Accurate pipe dimension data is important for piping layouts, spool drawings, support design, structural load review, and material takeoff. Knowing that this pipe weighs 141.12 kg/m helps with transport estimates, lifting plans, and support loading. If the pipe is filled with water, the total weight increases to 415.24 kg/m, which is also useful for operating load calculations.
Common Uses of DN600 Schedule 20 Pipe
DN600 Schedule 20 pipe may be referenced in industrial utility systems, water transfer lines, plant layout studies, process piping documentation, and engineering design work. It is also commonly used by piping designers, CAD users, estimators, and procurement teams who need fast access to standard steel pipe dimensions.
Difference Between NPS 24 and DN600
NPS 24 is the inch-based nominal pipe size designation, while DN600 is the metric nominal diameter reference. Both refer to the same pipe size category on this page. The actual standard outside diameter for this size is 610 mm.

Conclusion
Schedule 20 Pipe 24 Inch (DN600) is an important large-diameter steel pipe reference for piping design, drafting, estimation, and fabrication work. With its 610 mm outside diameter, 9.53 mm wall thickness, and 141.12 kg/m pipe weight, it provides useful dimensional data for engineers and designers who need fast and accurate pipe information.
Note: NPS = Nominal Pipe Size, DN = Diameter Nominal. Dimensions and weights shown here are based on ASME B36.10 steel pipe data.
How to Read This Pipe Reference
The table separates the pipe’s nominal designations from its physical dimensions. NPS 24 and DN600 identify the same nominal pipe size category, while the listed outside diameter is the dimension normally coordinated with layouts, clamps, supports, sleeves, and other external clearances.
The listed inside diameter is useful as a dimensional reference for flow-area studies and connection coordination. It should not be treated as a complete hydraulic design result because flow calculations also depend on the fluid, operating conditions, internal roughness, fittings, valves, and the overall piping system.
Using the Weight Information
The dry pipe weight can support preliminary estimating, lifting discussions, transport planning, and support-load review. The water-filled figure provides a separate reference for a pipe containing water; it should not automatically be treated as the complete operating load for every service. Insulation, coatings, valves, fittings, supports, contents, test conditions, and project-specific load combinations may also need to be considered.
Drafting and CAD Coordination
For CAD work, use the listed outside diameter for the pipe envelope and the listed wall thickness when an accurate section representation is required. The downloadable DWG can help with drafting workflows, but the final model should be checked against the approved project specification and the dimensions required by connected fittings, flanges, valves, and equipment.
Checks Before Design Use
- Confirm that the selected pipe standard and material match the project requirements.
- Check whether the connected components use compatible nominal size and dimensional references.
- Review pressure, temperature, corrosion, fabrication, and inspection requirements separately from the dimensional table.
- Use the appropriate empty, operating, test, and other project load cases for support or structural review.
- Compare adjacent size references when developing a layout or evaluating a routing alternative.
Frequently Asked Questions
What is the nominal size of this Schedule 20 pipe?
This page covers NPS 24, also identified as DN600. These are nominal designations; they should not be interpreted as the exact measured inside or outside diameter.
What does Schedule 20 identify?
Schedule 20 identifies the wall-thickness series for the pipe size shown. The applicable wall thickness, inside diameter, outside diameter, and weight are listed in the reference content on this page.
Can the listed weight be used for support design?
It can be used as an initial pipe-weight reference, but support design requires the project load cases and any additional loads from contents, insulation, fittings, valves, testing, thermal effects, and other specified conditions.
Is the water-filled weight the total operating load?
It is a reference for the pipe filled with water. Actual operating or design load review may require additional items and project-specific conditions, so the value should be checked before final engineering use.
Where can I use the downloadable DWG?
The DWG may assist with preliminary layouts, drafting, and coordination. Verify the drawing against the approved dimensions, connected components, and project design documents before issuing fabrication or construction information.
