This reference provides the listed dimensions and weight for Schedule 80S Pipe 3/8 Inch (DN10), along with practical guidance for reading the data in piping layouts, material take-offs, and procurement documents. Use the dimensional values below to coordinate pipe with compatible fittings, flanges, supports, and connection details.
Because NPS and DN are nominal designations, they should be read together with the listed outside diameter, inside diameter, and wall thickness. For broader terminology, compare this page with the pipe dimensions reference and the pipe schedule guide.

What Is Schedule 80S Pipe?
Schedule 80S is a stainless steel pipe schedule designation commonly used under ASME B36.19. In piping design and fabrication, the schedule identifies the wall thickness series for a given nominal pipe size. This helps engineers, buyers, and fabricators confirm dimensional compatibility, estimate pipe weight, and coordinate with fittings, flanges, and supports.
Common Uses of 3/8 Inch Schedule 80S Pipe
3/8 inch Schedule 80S pipe is commonly used in stainless steel piping systems that require good corrosion resistance, dependable wall thickness, and reliable service performance. This size is often selected for smaller process lines, utility piping, and installations where standard dimensions are needed for design, fabrication, procurement, and maintenance work.
- Process piping systems in chemical and industrial plants
- Utility and service piping for water, air, and general process lines
- Cooling water and auxiliary piping in plant facilities
- Marine and offshore piping where stainless steel is preferred
- Food and beverage plants requiring corrosion-resistant piping materials
- Pharmaceutical facilities using stainless steel process lines
- Instrument and small-bore piping systems in industrial service
- Pipeline modification and replacement work where standard pipe dimensions are required
In practical engineering work, this pipe size may be checked when reviewing flow area, piping layout, support spacing, transport weight, and installation requirements. Final pipe selection should always be verified against project pressure, temperature, fluid type, and material specifications.
Why OD, ID, Thickness, and Weight Matter
Exact OD, ID, wall thickness, and weight values are important for support design, material take-off, welding preparation, transport planning, and installation work. Weight data is also useful for estimating handling loads, while inside diameter affects flow calculations and service capacity review.
NPS 3/8 and DN10 Explained
NPS means nominal pipe size in inch units, while DN means diameter nominal in metric units. The current page identifies this pipe as NPS 3/8 and DN10, which is the standard naming format widely used in piping drawings, isometrics, and procurement specifications.
Conclusion
Schedule 80S Pipe 3/8 Inch (DN10) is listed on the current page with 17.1 mm OD, 10.7 mm ID, 3.2 mm wall thickness, and 1.1 kg/m weight. It is a useful stainless steel pipe reference for piping engineers, designers, and buyers who need standard dimensional and weight data for project planning and material selection.
How to Use This Schedule 80S Pipe Data
The table is most useful when several project tasks depend on the same pipe reference. The outside diameter supports layout coordination and connection checks, while the inside diameter helps establish the available flow passage for engineering review. Wall thickness is relevant to fabrication, welding preparation, and dimensional identification. The listed weight can support material take-offs, handling plans, and preliminary support-load coordination.
Schedule 80S identifies a stainless steel wall-thickness series; it is not, by itself, a complete design qualification or pressure rating. Final selection requires review of the applicable material specification, fluid, operating temperature, pressure, joining method, corrosion requirements, and project design rules. Confirm compatibility before ordering pipe, fittings, valves, or accessories.
Coordination With Fittings, Flanges, and Drawings
When this pipe is used in a model or piping isometric, keep the NPS designation, DN designation, schedule, and material description consistent across the line list, bill of materials, and fabrication documents. Also check that connected components are identified for the same nominal size and compatible dimensional standard. Related references include the pipe fittings guide and pipe flange reference.
The downloadable DWG can be useful for drafting and layout coordination. Treat CAD geometry as a reference and verify dimensions against the authoritative project data before fabrication, especially where tolerances, weld details, end preparation, or component interfaces are critical. See the site’s pipe CAD and DWG resources for related drawing references.
Frequently Asked Questions
What does 3/8 inch mean in this pipe designation?
3/8 inch is the NPS designation shown for this pipe. It is a nominal size label rather than a direct statement of the measured outside diameter.
What is the DN designation for Schedule 80S Pipe 3/8 Inch?
The corresponding metric designation listed on this page is DN10. NPS and DN are used together to identify the nominal pipe size in drawings, specifications, and purchasing documents.
Does Schedule 80S define the pipe material grade?
No. Schedule 80S identifies a stainless steel dimensional schedule, but the material grade and other procurement requirements must be stated and verified separately in the project specification.
Can the listed pipe weight be used for support design?
The listed weight is useful for preliminary material, handling, and support-load coordination. Final support design should also account for contents, insulation, valves, fittings, operating conditions, and the applicable engineering requirements.
Is a DWG file available for this pipe?
Yes. The page includes a downloadable DWG reference for Schedule 80S Pipe 3/8 Inch (DN10). Confirm the drawing against the page data and project requirements before using it for fabrication.
