This reference provides the dimensional and weight data for 10 inch Schedule 80 pipe, also identified as DN250. Use the table to check the outside diameter, inside diameter, wall thickness, and mass per unit length when preparing piping layouts, material takeoffs, support studies, or fabrication documents.
Schedule information describes the pipe wall category, while the nominal size is used for identification rather than as a direct measurement of the outside or inside diameter. For related drafting work, compare this page with the site’s pipe dimensions reference, pipe schedule guide, and pipe fittings resources before coordinating connected components.
Schedule 80 Pipe 10 Inch (DN250) is a heavy wall steel pipe commonly used in industrial piping systems that require higher strength and thicker pipe walls than lighter schedules. This pipe size is based on ANSI/ASME B36.10 and is widely used in process piping, utility systems, water treatment plants, and mechanical services. For this size, the standard data shows an outside diameter of 273.1 mm, an inside diameter of 242.82 mm, a wall thickness of 15.09 mm, and a pipe weight of 95.98 kg/m.

What Is Schedule 80 Pipe?
Schedule 80 refers to a pipe wall thickness classification. For the same nominal pipe size, a Schedule 80 pipe has a thicker wall and a smaller inside diameter than lower schedule pipes. This makes it a practical choice for systems that need additional pipe strength, durability, and long-term service performance.
Why 10 Inch DN250 Pipe Dimensions Matter
Knowing the exact dimensions of a 10 inch Schedule 80 pipe is important for piping design, fabrication, and installation. The outside diameter helps with flange matching, clamps, and supports. The inside diameter affects flow area and system capacity. The wall thickness is important for strength and service conditions, while the pipe weight per meter is useful for transport, lifting plans, and structural support calculations.
Common Uses of Schedule 80 Pipe 10 Inch (DN250)
This pipe size is often used in industrial and commercial piping systems such as:
- Water treatment and utility piping
- Process and plant piping systems
- Oil and gas applications
- Pump stations and mechanical services
- Heavy-duty industrial pipe networks

| NPS | DN | OD (mm) | ID (mm) | Wall Thickness (mm) | Weight (kg/m) |

| 10 inch | 250 | 273.1 | 242.82 | 15.09 | 95.98 |
Additional Information for Engineers and Buyers
Before selecting this pipe size, it is also important to review the material grade, end type, design pressure, corrosion allowance, operating temperature, and project code requirements. While Schedule 80 defines the dimensional wall category, the final pipe selection should always match the actual service condition and engineering specification.
Note: NPS means nominal pipe size in inches, while DN means diameter nominal in millimeters. These are standard reference sizes used for pipe identification.
How to Use the 10 Inch Schedule 80 Pipe Data
The listed outside diameter is the primary dimensional reference for components that fit around the pipe, including clamps, supports, sleeves, and connections requiring an external fit. The inside diameter is more relevant to flow-area checks and internal clearance. Because schedule changes the wall category, pipes with the same nominal size can have different internal dimensions.
Use the wall thickness when reviewing fabrication details, corrosion allowances, inspection requirements, and compatibility with the project specification. The listed pipe weight supports preliminary material estimates, handling plans, and support-load reviews. Any design check should also account for the pipe’s material, contents, insulation, fittings, valves, thermal effects, and applicable project requirements.
Coordination With Fittings, Flanges, and CAD Files
Nominal size and schedule should be checked together when selecting mating components. Flange, fitting, gasket, and valve information may be presented in separate reference tables, so confirm that the component dimensions and rating match the piping specification rather than relying on nominal size alone. The downloadable DWG file can support layout and drafting workflows, but the drawing should be reviewed against the project’s approved dimensional and material requirements before fabrication.
For broader coordination, useful next references include pipe flange dimensions, fitting dimensions, piping terminology, and CAD and DWG resources.
Selection Checks Before Purchasing
- Confirm the material grade and applicable pipe specification.
- Check the required end type and connection details.
- Review design pressure, operating temperature, and corrosion allowance.
- Verify code, inspection, coating, and project documentation requirements.
- Coordinate the pipe weight with lifting, transport, and support planning.
Frequently Asked Questions
What does Schedule 80 mean for this pipe?
Schedule 80 identifies a relatively heavy wall category for the stated nominal pipe size. Compared with a lighter schedule of the same nominal size, it generally has a thicker wall and a smaller internal opening. The applicable table provides the dimensions for this specific pipe entry.
Is 10 inch pipe the same as DN250 pipe?
In this reference, 10 inch is the nominal pipe size and DN250 is its metric nominal designation. These identification systems do not mean that every listed pipe dimension equals the nominal label, so use the published outside diameter, inside diameter, and wall thickness for technical coordination.
Which dimension should be used for a pipe support or clamp?
For components that fit around the pipe, start with the published outside diameter. Check the support or clamp manufacturer’s requirements, tolerances, coating assumptions, and load rating before finalizing the detail.
Does pipe weight include the contained fluid?
The reference separates the pipe weight from the listed pipe weight including water. For an actual system load, verify the contents, insulation, fittings, valves, and other attached items used in the engineering calculation.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference for this pipe entry. Review it against the authoritative project specification, approved drawings, material requirements, and connected-component dimensions before using it for fabrication or construction.
