Use this page as a quick reference when checking NPS 5 Schedule 10S pipe for piping layouts, fabrication drawings, material estimates, and engineering documentation. The table provides the dimensional and weight data for the stainless steel pipe size identified as 5 inch and DN125.
For broader design work, compare this entry with related pipe schedule references, stainless steel fittings, flange dimensions, and piping terminology resources. The downloadable DWG can also support drafting workflows, but project drawings should be checked against the applicable specifications and supplier information before fabrication.

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 āSā designation is commonly used for stainless steel pipe schedules.
Typical Uses of 5 Inch Schedule 10S Pipe
NPS 5 Schedule 10S pipe is commonly used in stainless steel piping systems for industrial plants, utility services, food and beverage facilities, water-related systems, 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.
5 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.

How to Read This Pipe Reference
The nominal size identifies the pipe designation used in piping systems; it is not a direct statement of the measured outside or inside diameter. For this entry, the table separates the nominal designations from the actual reference dimensions, including outside diameter, wall thickness, and inside diameter.
The outside diameter is especially useful when coordinating pipe with fittings, flanges, supports, clamps, and drawing geometry. Wall thickness helps distinguish this schedule from other options for the same nominal size, while the inside diameter is a useful dimensional reference for layout and checking available flow space. Final process, pressure, corrosion, and mechanical design decisions require the applicable project requirements and engineering verification.
Using the Weight Data
The dry pipe weight can support material takeoffs, handling plans, support-load estimates, and transportation discussions. The separate filled-with-water value is relevant when considering an operating or temporary load condition. For procurement and fabrication, treat the listed values as reference data because actual delivered pipe can vary with manufacturing tolerances, material grade, and supplier practices.
Drafting and CAD Coordination
The downloadable DWG is useful as a starting point for piping layouts and dimensional coordination. Before issuing a drawing, verify the drawing units, connection details, orientation, project layer conventions, and compatibility with the selected fittings and flanges. Related internal resources on pipe dimensions, schedules, fittings, flanges, and CAD references can help keep the surrounding model consistent.
Additional Questions About 5 Inch Schedule 10S Pipe
Are NPS 5 and DN125 used for the same pipe reference?
Yes. This page uses NPS 5, 5 inch, and DN125 to identify the same nominal pipe size. The dimensional values in the table should be used for the actual reference geometry.
Does the listed pipe weight include the water-filled condition?
No. The page distinguishes the pipe weight from the separate weight listed for pipe filled with water. Use the condition that matches the load case being reviewed, and confirm project assumptions before final support or lifting calculations.
Can the DWG be used directly for fabrication?
The DWG is a drafting reference rather than a substitute for an approved fabrication drawing. Check units, dimensions, material requirements, joining details, tolerances, and project specifications before using it for fabrication or procurement.
