This reference page explains the dimensional data for Schedule 5S Pipe 3/8 Inch (DN10) and places the tabulated values in a practical piping-design context. Use the table for dimensional checks, then review the schedule, material, fittings, and service requirements before preparing a final design or purchase specification.
For related work, readers may also want to compare other pipe schedules, review NPS and DN terminology, and check matching stainless steel fittings and flanges. The downloadable DWG reference can support preliminary routing, spool coordination, and drafting workflows, but connection details should be verified against the applicable component data.
Schedule 5S Pipe 3/8 Inch (DN10 mm) is a stainless steel pipe size commonly used in small-bore piping systems where corrosion resistance and lighter wall thickness are required. This pipe size is typically referenced under ANSI/ASME B36.19, which is the standard used for stainless steel pipe dimensions.
For this size, the pipe has an outside diameter (OD) of 17.1 mm, an inside diameter (ID) of 15.9 mm, and a wall thickness of 1.2 mm. The listed pipe weight is 0 kg/m, while the weight including water is 0.22 kg/m.
Schedule 5S Pipe 3/8 Inch (DN10 mm) Dimension Table
| Pipe Size | NPS | DN | Outside Diameter (OD) | Inside Diameter (ID) | Wall Thickness | Weight |
|---|---|---|---|---|---|---|
| Schedule 5S Pipe | 3/8 Inch | DN10 | 17.1 mm | 15.9 mm | 1.2 mm | 0 kg/m |
What Is Schedule 5S Pipe?
Schedule 5S is a thin-wall stainless steel pipe schedule listed in ASME B36.19. The āSā designation is commonly used for stainless steel pipe schedules. Compared with heavier schedules, Schedule 5S provides a lighter wall thickness and lower pipe weight, which can help reduce handling effort, support load, and fabrication requirements in suitable applications.
However, pipe schedule selection should always be reviewed against design pressure, temperature, corrosion allowance, project code, and service conditions before final use.

Why DN10 Pipe Dimensions Matter
Many users search for DN10 pipe dimensions to verify piping layout, support spacing, fabrication requirements, and compatibility with fittings or connected equipment. For this pipe size, accurate dimensions are important for spool coordination, line routing, and installation planning.
Knowing the correct 3/8 inch Schedule 5S pipe dimensions also helps engineers, designers, estimators, buyers, and students compare this size with other schedules when reviewing wall thickness, internal flow area, and total pipe weight.
NPS 3/8 and DN10 Explained
NPS stands for Nominal Pipe Size in inches, while DN stands for Diameter Nominal in metric designation. For this pipe size:
- NPS 3/8 = inch-based nominal pipe size
- DN10 = 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 17.1 mm.
Reference for Schedule 5S Pipe 3/8 Inch
This page provides a quick dimensional reference for engineers, piping designers, students, fabricators, and procurement teams looking for Schedule 5S Pipe 3/8 Inch (DN10 mm) data in a clear format.
Reference Standard: ANSI/ASME B36.19 stainless steel pipe dimensions.
How to Read This Schedule 5S Pipe Reference
The dimensional table separates nominal identification from physical pipe geometry. NPS 3/8 and DN10 identify the nominal size, while outside diameter, inside diameter, and wall thickness describe the pipe itself. This distinction is important when checking clearances, fitting interfaces, instrument connections, and available internal flow space.
The listed pipe weight and weight including water should be treated as reference values from the local table. When estimating supports, lifting requirements, or operating loads, confirm which weight basis applies and account for the actual project configuration, contents, insulation, valves, and attachments where applicable.
Schedule 5S Selection and Design Checks
Schedule designation alone does not establish whether a pipe is appropriate for a particular service. Before specifying or fabricating this size, review the design pressure, temperature, corrosion allowance, material requirements, joining method, and governing project code. The dimensional standard helps establish pipe geometry; it does not replace the engineering checks required for the complete piping system.
These checks are especially useful when comparing Schedule 5S with another stainless steel schedule. A change in wall thickness can affect internal clearance, mass, fabrication details, connection compatibility, and design verification. Confirm the selected schedule at interfaces with fittings, valves, flanges, tubing, and equipment nozzles rather than relying on nominal size alone.
Using the DWG Reference
The available DWG file can be useful for preliminary CAD layout and coordination. Before incorporating it into a fabrication package, verify the drawing units, layer conventions, connection details, tolerances, and project-specific drafting requirements. The dimensional table remains the local reference for the values presented on this page.

Frequently Asked Questions
What does Schedule 5S mean?
Schedule 5S identifies a thin-wall stainless steel pipe schedule referenced in the dimensional standard cited on this page. The schedule describes dimensional characteristics; service suitability still requires a separate engineering review.
Are NPS 3/8 and DN10 the actual pipe diameters?
No. NPS 3/8 and DN10 are nominal designations. The actual outside diameter, inside diameter, and wall thickness should be taken from the applicable dimensional table.
Why should the outside diameter be checked when the nominal size is known?
Outside diameter affects fit-up, routing clearance, clamps, supports, fittings, and equipment connections. Nominal designations are useful for identification, but they do not replace the dimensional values used for coordination.
Can the listed weight be used directly for support design?
Use the listed value as a reference for the pipe data, then confirm the applicable weight basis and include other system loads. Support design should consider the complete installed piping arrangement and project requirements.
What should be checked before using Schedule 5S Pipe 3/8 Inch?
Review pressure, temperature, corrosion allowance, material compatibility, project code, joining method, fittings, and connected equipment. The final selection should be verified by the responsible engineer or design authority.
What is the DWG file used for?
The DWG reference can assist with preliminary CAD layout, line routing, and coordination. Check its units and project drafting requirements before using it in fabrication or construction documentation.
