Schedule XS Pipe 24 Inch (DN600) is a reference for engineers, drafters, fabricators, estimators, and construction teams working with large-diameter steel piping. In addition to the source dimensions, this page explains how outside diameter, inside diameter, wall thickness, and unit weight affect common project decisions.
Use the dimensional data for preliminary layout, material takeoff, CAD coordination, and fabrication review. Always confirm the applicable material specification, manufacturing tolerance, end preparation, corrosion allowance, design conditions, and project requirements before releasing drawings or purchasing pipe.
Schedule XS Pipe 24 Inch (DN600) is a large steel pipe size used in industrial piping systems, utility lines, water transmission projects, plant construction, and heavy fabrication work. This page provides a practical reference for the main dimensions and weight of 24 inch XS pipe based on ANSI/ASME B36.10.
For piping engineers, CAD designers, estimators, fabrication teams, and site supervisors, accurate pipe size data is important for layout work, material takeoff, support design, transport planning, and installation checks. This guide presents the essential dimensions in a cleaner format that adds more value than a simple size table.

What Does Schedule XS Mean?
Schedule XS stands for Extra Strong. It is a pipe wall designation used in steel pipe standards. The selected schedule affects the wall thickness, which directly affects the inside diameter, pipe weight, fabrication requirements, and support loading.
For a large size such as 24 inch DN600 pipe, wall thickness matters even more because it has a strong effect on lifting weight, handling, structural loading, and installation planning in real projects.
Why 24 Inch DN600 Pipe Dimensions Matter
Knowing the exact dimensions of 24 inch Schedule XS pipe is useful for several engineering and construction tasks:
- Fabrication: OD and wall thickness are needed for cutting, beveling, welding, and fit-up work.
- Support Design: Pipe weight per meter helps engineers check support spacing and structural loads.
- Flow Review: ID is useful for estimating internal flow area and hydraulic performance.
- Transport and Lifting: Large pipe sections require reliable weight data for safe handling.
- Schedule Comparison: Engineers often compare XS with STD, Sch 40, Sch 60, or Sch 80 during design review.
Typical Applications of 24 Inch Schedule XS Pipe
This pipe size may be used in:
- Industrial process piping
- Water transmission systems
- Power and utility projects
- Large plant piping works
- Infrastructure construction
- Custom steel fabrication and spool projects
Engineering Notes
NPS means Nominal Pipe Size, while DN means Diameter Nominal. Although this pipe is called 24 inch, the actual outside diameter is 610 mm according to the standard. The inside diameter changes with the pipe schedule because wall thickness changes from one schedule to another.
That means if you compare the same 24 inch pipe in a different schedule, the OD usually stays the same, while the ID, wall thickness, and pipe weight will change.
Reference
The dimension data on this page is based on ANSI/ASME B36.10, which is widely used for carbon steel pipe dimensions in industrial applications.
How to Use This 24 Inch XS Pipe Reference
The listed outside diameter is the primary interface dimension for many layout and connection checks. It is relevant when coordinating pipe with fittings, flanges, clamps, supports, sleeves, and other components. The inside diameter is more useful for reviewing the available flow passage and checking clearances through the pipe bore.
Wall thickness connects these dimensions: for the same nominal pipe size, a heavier schedule generally leaves less internal passage while adding steel mass. This is why schedule selection should be kept consistent across piping layouts, spool drawings, bills of material, and procurement documents.
Drafting and Fabrication Considerations
- Use the outside diameter when checking physical envelope dimensions and support interfaces.
- Use the inside diameter when reviewing bore alignment, internal clearance, and preliminary flow calculations.
- Use the listed weight for estimating handling and support loads, while confirming the complete design load with project engineering.
- Check the pipe schedule and nominal designation together; a nominal size is not necessarily the measured outside diameter.
- For CAD work, review the downloadable DWG and confirm drawing units, tolerances, weld details, and connection standards before incorporating it into a project model.

FAQ
What does XS mean in pipe sizing?
XS means Extra Strong. It identifies a heavier pipe wall designation and is associated with the wall thickness, internal diameter, and unit weight shown in the reference data.
Is 24 inch the same as the measured outside diameter?
No. The 24 inch description is a nominal pipe size designation. The actual outside diameter is the standardized dimensional value listed on this page.
Why are both OD and ID important?
Outside diameter is important for physical fit, supports, sleeves, and connections. Inside diameter is important for bore clearance and preliminary flow-area review. Both should be checked when coordinating a piping system.
Can the listed weight be used for support design?
The listed pipe weight is useful for preliminary load review and material planning. Final support design should also consider the pipe contents, insulation, valves, fittings, testing condition, environmental loads, support arrangement, and the governing project criteria.
Can the DWG be used directly for fabrication?
The DWG is a useful drafting reference, but it should be checked against the project specification, material documentation, connection details, tolerances, and the approved fabrication procedure before use.
