This reference page helps engineers, designers, fabricators, estimators, and procurement teams interpret the dimensional data for Schedule 60 Pipe 8 Inch (DN200). Use the table for an initial check of outside diameter, inside diameter, wall thickness, and pipe weight, then confirm the complete project specification before fabrication or installation.
The page also clarifies how NPS and DN designations relate, why schedule selection affects piping layouts and support coordination, and where the downloadable DWG can assist with drafting workflows.
Schedule 60 Pipe 8 Inch (DN200 mm) is a carbon steel pipe size commonly used in heavy-duty piping systems where higher wall thickness and stronger mechanical performance are required. This pipe size is typically referenced under ANSI/ASME B36.10, which is the standard used for wrought steel pipe dimensions.
For this size, the pipe has an outside diameter (OD) of 219.1 mm, an inside diameter (ID) of 198.48 mm, and a wall thickness of 10.31 mm. The listed pipe weight is 53.09 kg/m, while the weight including water is 84.01 kg/m.
Schedule 60 Pipe 8 Inch (DN200 mm) Dimension Table
| Pipe Size | NPS | DN | Outside Diameter (OD) | Inside Diameter (ID) | Wall Thickness | Weight |
|---|---|---|---|---|---|---|
| Schedule 60 Pipe | 8 Inch | DN200 | 219.1 mm | 198.48 mm | 10.31 mm | 53.09 kg/m |
What Is Schedule 60 Pipe?
Schedule 60 pipe is a heavier wall steel pipe schedule used when a thicker pipe wall is needed compared with lighter schedules such as Schedule 40. In general, a thicker wall can provide improved strength, durability, and pressure-handling capability, depending on material grade, design temperature, and service conditions.
Pipe schedule selection should always be checked against project requirements such as design pressure, temperature, corrosion allowance, piping code, and fabrication method before final use.

Why DN200 Pipe Dimensions Matter
Many users search for DN200 pipe dimensions to verify pipe routing, support loads, fabrication details, transport limits, and compatibility with fittings or connected equipment. For an 8 inch pipe, accurate dimensional data is important for spool fabrication, structural checks, and installation planning.
Knowing the correct 8 inch Schedule 60 pipe dimensions also helps engineers, detailers, estimators, buyers, and students compare this pipe size with other schedules when reviewing wall thickness, internal flow area, and total pipe weight.
NPS 8 and DN200 Explained
NPS stands for Nominal Pipe Size in inches, while DN stands for Diameter Nominal in metric designation. For this pipe size:
- NPS 8 = inch-based nominal pipe size
- DN200 = metric nominal designation
Although DN is shown in metric form, the actual outside diameter should always be checked from the dimensional standard. For this size, the OD is 219.1 mm.
Reference for Schedule 60 Pipe 8 Inch

Reference Standard: ANSI/ASME B36.10 steel pipe dimensions.
How to Use This Schedule 60 Pipe Reference
Start with the dimension table when checking a piping layout, equipment connection, spool drawing, or material takeoff. The outside diameter is the key envelope dimension for clearances, clamps, supports, and connection coordination. The inside diameter is used when reviewing the available flow passage and compatibility with connected components. Wall thickness helps distinguish this schedule from lighter or heavier alternatives.
Pipe weight is important for support spacing studies, lifting plans, transportation, and structural load checks. The listed weight including water should be treated as a reference for a filled-pipe condition; actual operating loads can also depend on fluid density, insulation, valves, fittings, corrosion allowance, and other attached items.
Design and Drafting Checks
- Confirm that the selected schedule matches the governing piping code, design pressure, temperature, material grade, and corrosion requirements.
- Check the stated outside diameter before coordinating fittings, flanges, supports, sleeves, and equipment nozzles.
- Use the inside diameter when a project calculation requires a dimensional basis for flow or internal clearance.
- Account for pipe, contents, insulation, fittings, and support reactions separately when developing layout or structural checks.
- Verify manufacturer and project requirements before release for procurement, fabrication, or construction.

Frequently Asked Questions
What are the dimensions of 8 inch Schedule 60 pipe?
The listed dimensions are an outside diameter of 219.1 mm, an inside diameter of 198.48 mm, and a wall thickness of 10.31 mm. Refer to the table above as the local dimensional reference for this page.
What is the difference between NPS 8 and DN200?
NPS 8 is the inch-based nominal pipe designation, while DN200 is the metric nominal designation. These labels identify the nominal size; they should not be used as a substitute for checking the actual outside diameter.
How much does 8 inch Schedule 60 pipe weigh?
The listed pipe weight is 53.09 kg/m. The listed weight including water is 84.01 kg/m. Use project-specific loading conditions for final support and structural checks.
Is Schedule 60 pipe interchangeable with Schedule 40 pipe?
Not automatically. Schedule changes can affect wall thickness, inside diameter, weight, connection details, and design checks. Confirm dimensional compatibility and project requirements before substitution.
What standard is referenced for these steel pipe dimensions?
The source data references ANSI/ASME B36.10 for wrought steel pipe dimensions. Material, pressure, temperature, fabrication, and inspection requirements may come from other project documents and should also be verified.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference and should be reviewed against the table, project specification, connected components, and fabrication requirements before it is used for shop or construction deliverables.
