This reference page is designed for engineers, drafters, fabricators, estimators, and purchasing teams checking a compact stainless steel pipe size. Use the dimensional table for quick verification, then review the schedule explanation and calculation notes before transferring the information into a drawing, material takeoff, or fabrication document.
For related reference work, compare this entry with the site’s broader pipe schedules, stainless steel pipe dimensions, pipe weight, fittings, and flange dimensions resources. The downloadable DWG can also support drafting workflows, but the drawing should be checked against the project specification and the applicable purchasing requirements.

Schedule 10S Pipe 3/8 Inch Data Table
| Pipe Size | DN | OD (mm) | Wall Thickness (mm) | ID (mm) | Weight (kg/m) |
|---|---|---|---|---|---|
| 3/8 inch | 10 | 17.1 | 1.65 | 13.8 | 0.63 |
What Does Schedule 10S Mean?
Schedule 10S is a stainless steel pipe schedule covered by ASME B36.19. For the same nominal pipe size, the outside diameter remains fixed while the wall thickness changes with the schedule. The “S” designation is commonly used for stainless steel pipe schedules.
Typical Uses of 3/8 Inch Schedule 10S Pipe
NPS 3/8 Schedule 10S pipe is commonly used in stainless steel piping systems for industrial plants, utility services, food and beverage facilities, small-bore service lines, and fabrication work where corrosion resistance and dimensional accuracy are important.
Why Pipe Weight Matters
Pipe weight per meter is useful for transport planning, lifting studies, support design, structural loading, fabrication estimates, and installation planning. In stainless steel piping systems, accurate weight data helps improve material handling, support spacing, and total project cost estimation.
3/8 Inch Schedule 10S Pipe Calculation Notes
The listed weight is based on standard stainless steel pipe dimensions using the outside diameter and wall thickness of the pipe. Actual product weight may vary slightly depending on manufacturing tolerance, material grade, and supplier standard.

Conclusion
Schedule 10S pipe 3/8 inch (DN10) has an outside diameter of 17.1 mm, wall thickness of 1.65 mm, inside diameter of 13.8 mm, and a weight of 0.63 kg/m. It is a useful reference for piping design, drafting, estimating, and stainless steel fabrication work.
How to Use This Pipe Reference
NPS and DN are nominal designations rather than direct measurements of the outside or inside diameter. For dimensional checks, use the listed outside diameter, wall thickness, and inside diameter instead of treating the nominal size as a measured dimension.
The outside diameter is especially useful when checking clearances, fitting interfaces, clamps, and drawing geometry. The inside diameter is more relevant to bore representation and flow-area checks. Wall thickness supports fabrication review and material takeoff work, but it should not be used by itself to determine allowable pressure or service suitability.
Schedule and Design-Verification Notes
Schedule 10S identifies the stainless steel schedule designation associated with the referenced dimensional standard. A schedule entry provides dimensional information; it does not, on its own, establish the pipe’s pressure rating, corrosion performance, weld procedure, or suitability for a particular service.
Before using this data for procurement or design approval, confirm the material grade, product specification, manufacturing requirements, tolerances, joining method, operating conditions, and project code requirements. Any pressure, structural, thermal, or process-system decision should be verified by the responsible engineer.
Using the Weight Data
The listed pipe weight is useful for estimating, handling, support calculations, and preliminary load assessments. The water-filled value can help with a loaded-pipe review, while actual installed loads may also include fittings, valves, insulation, lining, supports, and contents other than water. Confirm the supplier’s certified product data when accurate shipment or final support loads are required.
Drafting and CAD Checklist
- Confirm that the drawing identifies the nominal size and Schedule 10S designation.
- Use the stated outside diameter and wall thickness when checking model or section geometry.
- Coordinate the pipe representation with connected fittings, valves, and flanges.
- Keep the DWG reference aligned with the project’s units, layer conventions, and revision controls.
- Verify all dimensions against the approved project specification before issuing fabrication or construction documents.

Additional Questions About 3/8 Inch Schedule 10S Pipe
Are NPS 3/8 and DN10 the same reference size?
On this page, NPS 3/8 and DN10 identify the same nominal pipe size. The actual dimensional checks should be made using the listed outside diameter, wall thickness, and inside diameter.
Does Schedule 10S alone define the pipe pressure rating?
No. Schedule 10S describes the referenced dimensional schedule. Pressure capability also depends on factors such as material specification, design conditions, temperature, joining details, manufacturing requirements, and the governing project code.
Can the listed weight be used as the final installed pipe load?
It is a reference weight per meter. A final installed-load assessment should also account for contents, fittings, valves, insulation, supports, and applicable product tolerances.
Why should the DWG be checked before use?
A CAD file is a drafting aid and should be coordinated with the dimensional table, project units, connected components, and approved design documents before it is used for fabrication or construction.
