This reference page is intended for engineers, designers, estimators, fabricators, and drafters who need a concise dimensional check for 24 inch Schedule 40 pipe. It brings together the NPS and DN designations, section dimensions, tabulated weight, and a downloadable DWG reference so the information can be applied consistently across layouts, takeoffs, and fabrication documents.
Use the dimensional data with related pipe dimensions and schedules references when comparing adjacent sizes. For complete layout work, also coordinate the pipe with applicable pipe fittings, flanges, supports, insulation, and equipment connection details rather than treating the pipe table as a complete design specification.
Schedule 40 pipe 24 inch (DN600) is a standard large-diameter steel pipe size commonly used in piping design, fabrication, drafting, and engineering estimation work. This page provides the standard dimensions and weight data for NPS 24 Schedule 40 pipe based on ANSI / ASME B36.10, including outside diameter, inside diameter, wall thickness, and weight per meter.
This size is commonly used in industrial piping systems, water transmission lines, utility networks, and fabrication projects where accurate dimensional data is important for layout, support design, material takeoff, and installation planning.

What Is 24 Inch Schedule 40 Pipe Used For?
24 inch Schedule 40 pipe is commonly used in medium to large industrial and utility piping systems where a standardized steel pipe size is required. Engineers, designers, and fabricators often use this size in:
- Water transmission and distribution systems
- Cooling water piping
- Industrial utility lines
- Process piping systems
- Plant layout and pipe rack coordination
- Fabrication and spool drawing preparation
Because this is a large pipe size, accurate dimensions and weight data are important for support design, lifting studies, transport planning, and material estimation.
Why These Dimensions Matter in Engineering
In piping and mechanical design, standard pipe dimensions are important for more than simple identification. The outside diameter is used for supports, clamps, insulation sizing, and equipment connection layouts. The inside diameter affects internal flow area and hydraulic calculations. The wall thickness is important for fabrication, welding preparation, and pipe strength, while the pipe weight per meter is essential for support load calculations and installation planning.
Using the correct DN600 Schedule 40 pipe dimensions helps reduce drafting errors, procurement mistakes, and field fit-up problems during construction and fabrication work.
24 Inch DN600 Schedule 40 Pipe for CAD and Drafting Work
For CAD, BIM, and piping drafting work, this size is commonly listed as NPS 24 or DN600. The standard OD of 610 mm is especially useful for routing clearance, support detailing, and nozzle or equipment connection references in both 2D drawings and 3D models.
This page can be used as a quick reference for 24 inch Schedule 40 pipe dimensions, DN600 pipe dimensions, and Schedule 40 steel pipe weight per meter during design, drafting, and estimation work.

How to Use This Pipe Reference
The nominal designation identifies the pipe size used in drawings, specifications, and procurement documents, while the DN designation provides the corresponding metric reference. The outside diameter is the primary envelope dimension for routing, supports, clamps, clearances, and connection coordination. The inside diameter is more relevant to flow-area and hydraulic checks.
Schedule is a dimensional designation associated with the pipe wall. It should not be treated as a substitute for material grade, pressure design, corrosion allowance, temperature limits, or the project piping specification. Those requirements must be checked separately against the governing design basis and procurement documents.
Weight and load coordination
The tabulated pipe weight is useful for material estimates, lifting plans, transport planning, and preliminary support-load work. A completed support calculation may also need to consider the contained fluid, insulation, coatings, valves, fittings, temporary loads, and project-specific load combinations. The listed water-filled value is a useful reference for a water-containing condition, but the applicable operating case should be confirmed for the project.
CAD, BIM, and drafting workflow
When preparing a 2D detail or 3D model, use the listed outside diameter and wall information to coordinate the pipe envelope and bore. Confirm connection details separately for fittings, flanges, valves, equipment nozzles, and branch components. The accompanying DWG can support drafting workflows, but imported geometry should still be checked against the project standard, units, layer conventions, and fabrication requirements.
For broader design work, this page can serve as a starting point before reviewing related pipe schedule tables, steel pipe weight references, and CAD/DWG pipe resources available elsewhere on the site.
Additional Questions About 24 Inch Schedule 40 Pipe
Are NPS and DN interchangeable in every document?
NPS 24 and DN600 identify the same nominal pipe size in this reference, but project documents may use one designation or both. Preserve the designation required by the applicable specification, drawing, or purchasing system.
Does Schedule 40 define the pipe material grade?
No. Schedule identifies a standardized wall designation; it does not by itself define the steel grade, manufacturing method, testing requirements, or service limits. Those items must come from the project specification and procurement documents.
Can the listed dimensions be used for pipe support design?
They provide important pipe geometry and weight inputs, but support design also requires the relevant contents, insulation, fittings, operating conditions, span, restraint arrangement, and project load criteria. Engineering verification is required before finalizing supports.
Why should the DWG be checked before use?
CAD files can inherit unit, layer, insertion-point, or compatibility settings from the drafting environment. Verify the imported geometry against the dimensional table and the conventions required by the project.
