Use this reference to verify the dimensional terminology and reported unit weight for 30 inch Schedule 10S pipe before preparing drawings, material takeoffs, support studies, or fabrication documents. The table below separates nominal size, outside diameter, wall thickness, inside diameter, and weight so each value can be used for its proper engineering purpose.
For drafting and coordination, keep the NPS designation, DN designation, and measured diameter fields distinct. Nominal size identifies the pipe size convention; it should not be treated as a direct measurement of the pipe outside diameter.
Schedule 10S pipe 30 inch (DN750) is a large-diameter stainless steel pipe size commonly used in piping design, fabrication, drafting, and engineering reference work. This page provides the standard dimensions, wall thickness, inside diameter, and weight per meter for NPS 30 Schedule 10S pipe based on ASME B36.19.

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 30 Inch Schedule 10S Pipe
NPS 30 Schedule 10S pipe is commonly referenced in large stainless steel piping systems used in industrial plants, water-related systems, utility services, food and process facilities, 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 large-diameter stainless steel piping systems, total line weight can significantly affect handling and support requirements.
30 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.

Conclusion
Schedule 10S pipe 30 inch (DN750) has an outside diameter of 762 mm, wall thickness of 7.92 mm, inside diameter of 746.16 mm, and a weight of 147.29 kg/m. It is a useful reference for piping design, drafting, estimating, and stainless steel fabrication work.
How to Use the 30 Inch Schedule 10S Reference
The outside diameter is the primary envelope dimension for layout, connection alignment, clearances, and coordination with fittings or flanges. The wall thickness is used when checking the pipe section represented in a drawing or material schedule, while the inside diameter is more relevant to bore clearance and flow-area calculations.
Use the reported pipe weight for preliminary handling, transport, support, and structural-loading discussions. The water-filled figure is a separate planning value and should not be confused with the pipe’s empty weight. Final support reactions, lifting arrangements, pressure design, and code compliance still require project-specific engineering review and the applicable material and fabrication requirements.
Related Pipe Reference Topics
This page works well alongside internal references for pipe schedules, stainless steel pipe dimensions, pipe weight calculations, flange dimensions, piping terminology, and CAD/DWG pipe resources. Linking those topics from this page helps readers move from a single size lookup to the broader dimensional and drafting information needed for a piping model or material takeoff.
Drafting and Procurement Check
When transferring this information into a drawing or purchase document, identify the nominal size, schedule, stainless steel designation, dimensional standard, and required product specification separately. Confirm the supplier’s published tolerances and actual product data before using the reference values for fabrication, lifting, or final design decisions.
Additional Questions About Schedule 10S Pipe
Is the nominal size the same as the outside diameter?
No. The nominal size is a standardized designation, while the outside diameter is the dimensional value used for physical layout and coordination.
Can the listed pipe weight be used as the final lifting weight?
It can support preliminary planning, but final lifting calculations should account for actual supplied pipe, fittings, attachments, coatings, contents, and the approved handling method.
Does Schedule 10S by itself establish the allowable pressure?
No. Pressure suitability depends on the applicable design code, material specification, temperature, corrosion allowance, manufacturing requirements, joints, and project conditions. Schedule information should not be used as a standalone pressure-design approval.
Why should the CAD/DWG reference be checked against the table?
The table provides a dimensional lookup, while a drawing resource may support drafting and model coordination. Verify that the drawing uses the same nominal size, schedule, dimensional standard, and units before incorporating it into project documents.
