This reference page is intended for engineers, designers, drafters, fabricators, estimators, and procurement teams checking Schedule 10S pipe 8 inch (DN200) dimensions. Use the table below as a quick dimensional reference, then confirm the project specification, material grade, manufacturing requirements, and applicable design code before ordering or using the pipe in a system.
The page also supports practical drafting and layout work by bringing the nominal size, outside diameter, wall thickness, inside diameter, and unit weight together in one place. The downloadable DWG file can be useful when preparing piping arrangements or checking how this pipe size relates to connected fittings and components.

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 8 Inch Schedule 10S Pipe
NPS 8 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.
8 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
NPS 8 and DN200 identify the same nominal pipe size in inch-based and metric terminology. These labels are nominal designations, so they should not be treated as a direct statement of the measured inside diameter. For layout and connection work, the listed outside diameter is especially important because fittings, flanges, supports, and other components must be coordinated with the pipe system.
The schedule identifies the wall-thickness selection for this stainless steel pipe size. It is not a material grade, corrosion allowance, pressure rating, or complete purchasing specification. Material selection and service suitability require the applicable project documents and engineering review.
Using the Dimensions in Design and Drafting
The outside diameter and wall thickness help establish the listed inside diameter, while the weight value supports material takeoffs, handling plans, support checks, and general estimating. Designers should distinguish between the pipe’s own unit weight and the additional loads from contents, insulation, valves, fittings, supports, thermal effects, and other system components.
For CAD work, compare the downloaded drawing with the project model, connection details, and the manufacturer’s supplied product information. A reference drawing is useful for geometry and coordination, but it does not replace a certified dimensional document or an approved fabrication drawing.
Related Pipe Reference Topics
Readers working with this entry may also need the site’s related references for pipe dimensions, pipe schedules, stainless steel pipe, flange dimensions, pipe fittings, and piping CAD/DWG resources. These topics provide useful next steps when coordinating a complete piping assembly rather than reviewing the pipe barrel alone.
Additional Questions About 8 Inch Schedule 10S Pipe
Is Schedule 10S a material grade?
No. Schedule 10S identifies a stainless steel pipe schedule and its associated dimensional selection. The material grade, product specification, and service requirements must be checked separately.
Can the listed dimensions be used to select fittings?
They can support preliminary coordination, but fittings, flanges, valves, and other components should be selected against their applicable dimensional standards and the approved project specification. Confirm compatibility before fabrication or installation.
Does the listed pipe weight include the contents of the pipe?
The page distinguishes the pipe weight from the listed weight for pipe filled with water. Other operating loads, such as insulation, fittings, supports, and process contents, require separate consideration.
Is the downloadable DWG a substitute for a fabrication drawing?
No. The DWG is a drafting and reference resource. Review it against the project model, connection details, supplier documentation, and approved fabrication requirements before issuing construction documents.
Why might delivered pipe weight differ from the reference value?
Actual product weight can vary with manufacturing tolerances, material grade, surface condition, length, and supplier practice. Use certified supplier documentation for purchasing, shipping, and final weight control.
