Schedule 5S Pipe 30 Inch (DN750 mm) Dimensions and Weight
Schedule 5S Pipe 30 Inch (DN750 mm) is a stainless steel pipe size commonly referenced for large-diameter piping systems where light wall thickness and corrosion resistance are important. This pipe size is listed under ANSI/ASME B36.19, which is the standard generally used for stainless steel pipe dimensions.
For this size, the pipe has an outside diameter (OD) of 762 mm, an inside diameter (ID) of 749.3 mm, and a wall thickness of 6.35 mm. The listed pipe weight is 118.34 kg/m, and the weight including water is 559.07 kg/m.
Schedule 5S Pipe 30 Inch (DN750 mm) Dimension Table
| Pipe Size | NPS | DN | Outside Diameter (OD) | Inside Diameter (ID) | Wall Thickness | Weight |
|---|---|---|---|---|---|---|
| Schedule 5S Pipe | 30 Inch | DN750 | 762 mm | 749.3 mm | 6.35 mm | 118.34 kg/m |
What Is Schedule 5S Pipe?
Schedule 5S is a thin-wall stainless steel pipe schedule. The āSā designation is typically used for stainless steel pipe schedules in ASME B36.19. Compared with heavier schedules, Schedule 5S provides a lighter pipe wall, which can help reduce total material weight and make handling, support design, and installation easier in suitable applications.
This does not mean Schedule 5S is suitable for every service. Pipe schedule selection should always depend on design pressure, temperature, corrosion allowance, service conditions, fabrication method, and project specification.

Where Schedule 5S Pipe 30 Inch Is Commonly Used
Large-diameter Schedule 5S stainless steel pipe may be used in systems where corrosion resistance and lower wall weight are beneficial. Typical applications can include:
- Water treatment and utility piping
- Food and beverage process lines
- Chemical and industrial piping systems
- Low-pressure stainless steel distribution lines
- Projects that require large OD stainless steel pipe with lighter wall thickness
Why DN750 Schedule 5S Pipe Dimensions Matter
Users often search for DN750 pipe dimensions to confirm compatibility with supports, fittings, insulation space, rolling, transport clearance, and layout requirements. For large pipe sizes such as 30 inch, dimension accuracy is especially important because even small design errors can affect fabrication, spool fit-up, and installation planning.
Checking the correct 30 inch Schedule 5S pipe dimensions also helps engineers, draftsmen, estimators, and buyers compare this size with other schedules when evaluating weight, flow area, and structural support requirements.
NPS and DN Explanation
NPS means Nominal Pipe Size in inch-based pipe systems, while DN means Diameter Nominal in metric designation. In this page:
- NPS 30 = nominal pipe size in inches
- DN750 = nominal metric designation
Although DN is a metric designation, the actual outside diameter must still be checked from the standard dimension table. For this pipe, the OD is 762 mm.

How to Read the 30 Inch Schedule 5S Pipe Data
The pipe size is identified using both NPS and DN. These are nominal designations rather than direct measurements of the pipe bore. For physical coordination, use the listed outside diameter, inside diameter, and wall thickness when checking clearances, connections, supports, insulation, and drawing geometry.
The outside diameter is especially important for layout and fit-up because it controls the external envelope of the pipe. The inside diameter is useful when reviewing flow space and internal clearance. Wall thickness supports fabrication and design checks, but it should not be used by itself to establish allowable pressure or service suitability.
Using the Weight Values in Design and Planning
The listed pipe weight can support preliminary material takeoffs, handling reviews, transportation planning, and support-load discussions. The separate water-included value represents the reference condition shown in the source table. Actual operating loads may also include fluid properties, insulation, lining, valves, fittings, temporary contents, and other attached components, so final support and structural checks require the complete system definition.
Schedule 5S, Fittings, and Drawing Coordination
When matching this pipe with fittings or flanges, compare the relevant outside diameter, wall condition, facing details, pressure class, material requirements, and joining method. Nominal size alone does not confirm interchangeability. A drafting review should also verify that connected components use compatible dimensional references.
For broader reference work, this page can be read alongside the site’s resources on pipe schedules, stainless steel pipe dimensions, NPS and DN terminology, pipe fittings, flanges, and piping support design. The available DWG download can help with preliminary drawing coordination, but project-specific geometry and connection details should be checked before fabrication.
Important Verification Before Specification
- Confirm that the selected schedule satisfies the project’s pressure, temperature, corrosion, and service requirements.
- Check material grade, specification, testing, joining, and fabrication requirements separately from dimensional data.
- Verify connected fittings, flanges, valves, gaskets, and supports against the applicable project documents.
- Use the listed dimensions for reference and coordination, not as a substitute for engineering design verification.
Frequently Asked Questions
What is the outside diameter of 30 inch Schedule 5S pipe?
The source table lists an outside diameter of 762 mm for this pipe size.
What is the wall thickness of Schedule 5S pipe in this reference?
The listed wall thickness is 6.35 mm. Confirm the applicable standard and project requirements before using it for fabrication or design.
What is the difference between NPS 30 and DN750?
NPS 30 is the inch-based nominal pipe designation, while DN750 is the metric nominal designation used to identify the same referenced pipe size. Neither designation should be treated as the measured inside diameter.
What does the water-included weight mean?
It is the combined reference weight shown in the source data for the pipe and water condition. Actual operating or support loads may differ when other contents, insulation, fittings, or attached equipment are included.
Can Schedule 5S be used for any low-pressure stainless steel line?
No. Schedule selection depends on pressure, temperature, corrosion allowance, service conditions, fabrication, and project specifications. Engineering verification is required before selecting the pipe for a specific system.
Is a CAD file available for this pipe?
The page includes a DWG download for the referenced pipe size. Review the drawing against the project model, connected components, and current fabrication requirements before relying on it for construction.
