This reference provides the dimensional data and practical context for Schedule 5S Pipe 4 Inch (DN100). Use the table to check the outside diameter, inside diameter, wall thickness, and listed weight when preparing piping layouts, material takeoffs, or fabrication documents.
For related sizing work, compare this page with the pipe schedules reference, review compatible pipe fittings, and check pipe flange dimensions before developing a complete piping arrangement. The downloadable CAD and DWG resources can also support drafting workflows.
Schedule 5S Pipe 4 Inch (DN100 mm) is a stainless steel pipe size commonly used in industrial 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 114.3 mm, an inside diameter (ID) of 110.08 mm, and a wall thickness of 2.11 mm. The listed pipe weight is 5.84 kg/m, while the weight including water is 15.35 kg/m.
Schedule 5S Pipe 4 Inch (DN100 mm) Dimension Table
| Pipe Size | NPS | DN | Outside Diameter (OD) | Inside Diameter (ID) | Wall Thickness | Weight |
|---|---|---|---|---|---|---|
| Schedule 5S Pipe | 4 Inch | DN100 | 114.3 mm | 110.08 mm | 2.11 mm | 5.84 kg/m |
What Is Schedule 5S Pipe?
Schedule 5S is a thin-wall stainless steel pipe schedule listed in ASME B36.19. The “S” 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 DN100 Pipe Dimensions Matter
Many users search for DN100 pipe dimensions to verify piping layout, support spacing, fabrication requirements, transport limits, and compatibility with fittings or connected equipment. For this pipe size, accurate dimensions are important for spool coordination, structural checks, and installation planning.
Knowing the correct 4 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 4 and DN100 Explained
NPS stands for Nominal Pipe Size in inches, while DN stands for Diameter Nominal in metric designation. For this pipe size:
- NPS 4 = inch-based nominal pipe size
- DN100 = 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 114.3 mm.

This page provides a quick dimensional reference for engineers, piping designers, students, fabricators, and procurement teams looking for Schedule 5S Pipe 4 Inch (DN100 mm) data in a clear format.
Reference Standard: ANSI/ASME B36.19 stainless steel pipe dimensions.
How to Use This Schedule 5S Pipe Reference
The dimensional table is useful for checking whether a pipe section will coordinate with a layout, fitting, flange, valve, or connected equipment. The outside diameter is especially important for external clearances, supports, clamps, and connection compatibility. The inside diameter helps describe the available flow passage, while the wall thickness identifies the metal thickness used in the listed dimensional reference.
The listed pipe weight describes the pipe itself. The separate water-inclusive value represents the listed weight when the pipe is filled with water, so the two values should not be treated as interchangeable in support, lifting, shipping, or installation checks.
Schedule Selection and Design Review
Schedule 5S identifies a stainless steel pipe dimensional series; it is not, by itself, a complete design approval or pressure rating. Final selection requires review of the applicable design code, material specification, operating pressure and temperature, corrosion or erosion conditions, joining method, and project requirements. A qualified engineer should verify suitability for the intended service.
Drafting and Procurement Checks
- Use the dimensional standard and the source table when checking the pipe envelope in a drawing.
- Confirm that connected fittings, flanges, valves, and equipment use compatible nominal size and outside-diameter requirements.
- Keep pipe-only weight separate from fluid-filled weight when estimating supports, handling, or transport loads.
- Confirm material grade, finish, length, end preparation, inspection requirements, and applicable purchase specifications separately from the dimensional schedule.
For a broader comparison, use the stainless steel pipe dimensions guide and compare other schedules without assuming that a thicker or thinner wall is suitable for a particular service.
Frequently Asked Questions
What does Schedule 5S mean?
Schedule 5S is a thin-wall stainless steel pipe schedule associated with the stainless steel pipe dimensional reference identified on this page. The “S” designation distinguishes stainless steel schedule usage from general carbon steel schedule references.
Are NPS 4 and DN100 the same designation?
NPS 4 is the inch-based nominal pipe designation, while DN100 is the metric nominal designation used for the same nominal size. The actual outside diameter should be checked from the applicable dimensional reference rather than inferred from the nominal designation alone.
What is the difference between pipe weight and weight including water?
Pipe weight refers to the listed mass of the empty pipe. Weight including water accounts for the pipe with its internal passage filled, making it relevant to certain support, handling, and installation checks.
Can Schedule 5S be selected from dimensions alone?
No. Dimensions establish the pipe geometry, but selection also requires review of pressure, temperature, corrosion allowance, material requirements, service conditions, and the governing project code.
Where can the DWG file be used?
The downloadable DWG resource can be used as a drafting reference for piping layouts and coordination. Its geometry should be checked against the project specification and connected-component requirements before issuing fabrication or construction drawings.
