This reference is designed for engineers, drafters, fabricators, estimators, and buyers checking the dimensional identity of 2 inch Schedule 5S stainless steel pipe. It brings together the NPS and DN designations, dimensional terms, listed weights, and practical coordination considerations in one place.
Use the source table for the controlling local values, then review the explanatory notes below when comparing schedules, preparing drawings, coordinating fittings, or checking whether a selected pipe meets the project design basis.
Schedule 5S Pipe 2 Inch (DN50 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 60.3 mm, an inside diameter (ID) of 57 mm, and a wall thickness of 1.65 mm. The listed pipe weight is 2.39 kg/m, while the weight including water is 4.94 kg/m.

| Schedule 5S Pipe | 2 Inch | DN50 | 60.3 mm | 57 mm | 1.65 mm | 2.39 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 DN50 Pipe Dimensions Matter
Many users search for DN50 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 2 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 2 and DN50 Explained
NPS stands for Nominal Pipe Size in inches, while DN stands for Diameter Nominal in metric designation. For this pipe size:
- NPS 2 = inch-based nominal pipe size
- DN50 = 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 60.3 mm.
Reference for Schedule 5S Pipe 2 Inch
This page provides a quick dimensional reference for engineers, piping designers, students, fabricators, and procurement teams looking for Schedule 5S Pipe 2 Inch (DN50 mm) data in a clear format.
Reference Standard: ANSI/ASME B36.19 stainless steel pipe dimensions.
How to Read the Schedule 5S Pipe Data
The dimension table separates nominal identification from the physical dimensions needed for drafting and coordination. NPS 2 and DN50 identify the nominal pipe size, while OD, ID, and wall thickness describe the pipe geometry used in layouts, sections, and connection details.
For CAD work, the outside diameter is especially important when checking clearances, clamps, guides, penetrations, and support details. The inside diameter is the relevant listed dimension for representing the internal passage and reviewing flow-area assumptions. These dimensions should not be inferred from the nominal size alone.
Pipe Weight and Water-Filled Weight
The listed pipe weight describes the pipe itself. The separate water-filled value represents the pipe together with the stated internal water condition. Keeping these values distinct helps prevent mistakes when preparing support reactions, transport estimates, lifting plans, or preliminary load checks.
Actual project calculations may also require consideration of insulation, coatings, valves, fittings, flanges, supports, contents, and operating conditions. Those items are not automatically included in the pipe weight shown in the source table.
Schedule Selection and Design Review
Schedule 5S identifies a stainless steel pipe wall designation; it does not by itself confirm that the pipe is acceptable for a particular service. Final selection should be checked against the governing design code, pressure and temperature requirements, corrosion allowance, material specification, joining method, inspection requirements, and project documentation.
When comparing this page with a pipe schedule comparison or another stainless steel pipe dimensions reference, confirm that the comparison uses the same nominal size, material family, dimensional standard, and measurement basis. A thinner wall can affect fabrication, threading or joining details, handling, and design verification.
Drafting and Procurement Checklist
- Show both the nominal designation and the applicable dimensional description on drawings and material requisitions.
- Use the listed OD when coordinating supports, penetrations, insulation space, and connected components.
- Check that fittings, flanges, valves, and other components are compatible with the selected pipe size and material requirements.
- Use the downloadable DWG as a drafting aid, then verify project-specific tolerances, connection details, and revision control before issuing fabrication documents.
- Confirm whether the specified weight basis includes only pipe or also contents and attached components.

Frequently Asked Questions
What is the OD of 2 inch Schedule 5S pipe?
The source data lists an outside diameter of 60.3 mm. OD is the external dimension used for many layout, clearance, and support checks.
What are the ID and wall thickness?
The listed inside diameter is 57 mm, and the listed wall thickness is 1.65 mm. Use the dimensional table as the controlling reference for this page.
What do NPS 2 and DN50 mean?
NPS 2 is the inch-based nominal pipe designation, while DN50 is the metric nominal designation. Neither designation should be treated as the actual outside diameter.
What is the listed pipe weight?
The listed pipe weight is 2.39 kg/m. The source also gives a separate weight including water of 4.94 kg/m; these values have different load-use contexts.
Does Schedule 5S confirm pressure suitability?
No. The schedule and dimensions identify the pipe geometry, but pressure and service suitability require review of the applicable design code, material requirements, temperature, corrosion allowance, joining details, and project conditions.
Can the downloadable DWG be used directly for fabrication?
The DWG is a useful drafting reference, but fabrication documents should be checked against the project specification, current revisions, connection details, tolerances, and required design approvals before issue.
