This reference page brings together the key dimensional and weight information for 10 inch Schedule 5 pipe, also identified as DN250. Use the source table for checking outside diameter, inside diameter, wall thickness, and unit weight during piping layout, fabrication, procurement, and drafting work.
For related design work, compare this reference with the site’s resources on pipe schedules, NPS and DN terminology, pipe fittings and flanges, and CAD/DWG piping details. Dimensional reference data should still be checked against the project specification, material requirements, joining method, and applicable engineering calculations before fabrication or installation.
Schedule 5 Pipe 10 Inch (DN250) is a steel pipe size commonly used in industrial piping systems that require good flow capacity with a relatively light wall thickness. This pipe size is often used in utility piping, water systems, low-pressure industrial service, and general steel pipe fabrication work.
This dimension data is based on ANSI/ASME B36.10, which is the standard commonly used for carbon steel pipe dimensions.

What Is 10 Inch Schedule 5 Pipe?
A 10 inch Schedule 5 pipe is a steel pipe with a nominal size of 10 inches and a relatively thin wall thickness compared with heavier schedules. For this size, the outside diameter is fixed at 273.1 mm, while the inside diameter is 266.2 mm based on a wall thickness of 3.4 mm.
Schedule 5 pipe is often selected when a project needs good flow capacity, reduced pipe weight, and easier handling compared with thicker wall pipes. It is commonly referenced in steel piping design, drafting, fabrication, and material takeoff work.
Where Is Schedule 5 Pipe 10 Inch Used?
This pipe size is commonly used in applications that need good flow capacity with relatively light wall thickness. Typical uses include:
- Water transfer and distribution systems
- Utility and low-pressure industrial piping
- Process and service lines
- Pipe spool fabrication and layout work
- General steel piping projects
Why Pipe Dimensions Matter
Accurate 10 inch Schedule 5 pipe dimensions are important for piping layout, fabrication, transport planning, support design, and installation work. Engineers and designers often check OD, ID, wall thickness, and weight before selecting supports, fittings, welding details, and handling methods.
The outside diameter is important for matching supports, clamps, and pipe accessories. The inside diameter helps estimate internal flow area and system capacity. The wall thickness affects mechanical strength and specification compliance, while the pipe weight per meter is useful for lifting plans, transport, and structural loading calculations.
10 Inch Schedule 5 Pipe Weight Information
The nominal weight of this pipe size is 22.61 kg/m. When filled with water, the combined weight becomes approximately 78.23 kg/m. This information is useful for pipe support design, structural coordination, and lifting preparation in piping systems.
Difference Between NPS 10 and DN250
NPS 10 is the inch-based nominal pipe size, while DN250 is the metric designation used in international drawings and specifications. Both terms refer to the same nominal pipe size, and users may search by either inch size or DN format depending on project standards.

Conclusion
Schedule 5 Pipe 10 Inch (DN250) has an outside diameter of 273.1 mm, an inside diameter of 266.2 mm, a wall thickness of 3.4 mm, and a weight of 22.61 kg/m. It is a useful steel pipe reference size for design, drafting, fabrication, and procurement work.
This page provides a quick reference for engineers, drafters, fabricators, and buyers who need reliable 10 inch Schedule 5 pipe dimensions and DN250 pipe dimensions in one place.
How to Use This 10 Inch Schedule 5 Pipe Reference
The table is most useful when several dimensions must be coordinated at once. The outside diameter supports checks for clamps, supports, sleeves, fittings, and clearances. The inside diameter is relevant to flow-area estimates and hydraulic coordination. Wall thickness is used when checking fabrication details and compatibility with the specified pipe material and service.
The listed pipe weight can support preliminary material takeoffs, handling studies, and support-load coordination. The water-filled value is useful when considering the additional operating load from the contents. Final support and structural decisions should account for the complete piping arrangement, including fittings, valves, insulation, attachments, test conditions, and project-specific design requirements where applicable.
Drafting and Procurement Checks
- Use the outside diameter when coordinating pipe supports, clamps, sleeves, and connection geometry.
- Use both NPS 10 and DN250 when searching drawings, catalogs, specifications, and supplier documentation.
- Confirm that the selected fittings and flanges match the pipe size, wall designation, connection type, and project standard.
- Check the pipe material and applicable product requirements separately; a schedule designation does not by itself define every requirement for a piping system.
- Use the downloadable DWG as a drafting resource, then verify dimensions against the authoritative table before releasing fabrication documents.
Useful related internal references include pipe dimension tables by schedule, carbon steel pipe standards, flange dimension references, pipe support design guidance, and the site’s DWG pipe detail library. These topics help connect the dimensional data to real drafting and coordination tasks without replacing project-specific engineering review.
Frequently Asked Questions
What is the nominal size of Schedule 5 pipe in this reference?
The pipe is identified as NPS 10 and DN250. These are inch-based and metric nominal designations for the same pipe size.
What dimensions should be checked before selecting fittings or supports?
Check the outside diameter, inside diameter, wall thickness, and pipe schedule. The outside diameter is particularly important for external supports and accessories, while the inside diameter helps with internal flow coordination.
Does Schedule 5 alone establish the pipe’s pressure rating?
No. A schedule designation describes a dimensional wall category, but a complete design check also depends on factors such as material, temperature, service conditions, corrosion considerations, joining details, and the governing project requirements.
Why are both pipe weight and water-filled weight shown?
The pipe-only weight supports handling and material planning. The water-filled value helps with preliminary coordination of operating loads and support requirements when the line contains water.
Which standard is identified for these dimensions?
The source content identifies ANSI/ASME B36.10 as the dimensional standard used for this carbon steel pipe reference. Always confirm the project specification and procurement documentation before ordering.
