What Does Schedule 140 Mean?
Schedule 140 refers to a very heavy wall thickness series used for steel pipe under ASME B36.10. For the same nominal pipe size, the outside diameter remains fixed while the wall thickness increases according to the schedule. A thicker wall reduces the inside diameter and significantly increases pipe weight.
Typical Uses of 24 Inch Schedule 140 Pipe
NPS 24 Schedule 140 pipe is commonly referenced for heavy-duty industrial piping systems where very high wall thickness is required. It may be used in process piping, plant utility systems, structural loading checks, fabrication work, and engineering applications where pipe strength and wall thickness are more critical than maximum flow area.
Why Pipe Weight Matters
Pipe weight per meter is essential for transport planning, crane lifting studies, support design, structural loading, fabrication estimates, and installation planning. For a 24 inch Schedule 140 pipe, the heavy wall thickness results in much higher installed weight than lighter schedules, so accurate weight data is important for engineering and construction work.
24 Inch Schedule 140 Pipe Calculation Notes
The listed weight is based on standard steel pipe dimensions using the outside diameter and wall thickness of the pipe. Actual product weight may vary slightly depending on manufacturing tolerance, material specification, and supplier standard.

How to Read This Schedule 140 Pipe Entry
Start with the nominal designations: NPS 24 and DN600 identify the same pipe size reference used in this entry. The outside diameter is the controlling envelope dimension for many layout, clearance, and fitting-connection checks, while the listed wall thickness is used to understand the pipe section and determine the stated inside diameter.
Schedule is not a material grade, pressure rating, or complete design specification. It identifies a wall-thickness series for the nominal pipe size. A fabrication or procurement document may also need material requirements, manufacturing requirements, end preparation, length, coating, and inspection details. Those requirements should be taken from the applicable project specification and verified by the responsible engineer.
Using the Dimensions in Drawings and Estimates
- Use the outside diameter when checking physical clearances, supports, clamps, insulation space, and connection geometry.
- Use the inside diameter when reviewing the available flow passage or preparing a hydraulic calculation that requires an internal dimension.
- Use the stated mass per meter for preliminary material takeoffs, handling studies, support loads, and transport planning.
- Keep empty-pipe and water-filled conditions distinct when preparing load cases; the source provides both values for this entry.
- When producing a CAD or DWG layout, verify that the selected fittings, flanges, valves, and connected components use compatible dimensional references.
Important Design Verification
The listed dimensions are useful reference data, but they do not by themselves establish allowable pressure, structural adequacy, corrosion life, flow capacity, or code compliance. Final selection should account for the governing piping code, material specification, operating conditions, loads, joining method, tolerances, and project requirements. Link this page to the site’s flange dimensions, pipe fittings, pipe support, and CAD/DWG reference resources to support those checks.
Additional Questions About 24 Inch Schedule 140 Pipe
Are NPS 24 and DN600 the same designation here?
Yes. In this reference, NPS 24 and DN600 identify the same nominal pipe size. The nominal designation should not be treated as the pipe’s measured inside diameter.
Can the schedule number be used as a pressure rating?
No. Schedule 140 describes a wall-thickness series. Pressure suitability also depends on material, temperature, design code, joining details, corrosion considerations, and other project requirements.
Which dimension should be used for a layout clearance?
Use the listed outside diameter when checking the pipe’s physical envelope. Add any required insulation, coating, access, or installation clearance separately according to the project requirements.
Why might delivered pipe weight differ from the reference value?
The source notes that actual product weight may vary because of manufacturing tolerance, material specification, and supplier practices. Use certified supplier data for purchasing, lifting, and final structural checks.
Where can this data be used in a drafting workflow?
It can support preliminary CAD or DWG layouts, pipe-routing studies, material takeoffs, fabrication references, and coordination checks. Confirm connected components and project-specific requirements before issuing a design for construction.
