Schedule 5S Pipe 6 Inch (DN150 mm) is a stainless steel pipe size commonly used in industrial piping systems where corrosion resistance and lighter wall thickness are required. This pipe size is typically referenced under ANSI/ASME B36.19, which is the standard used for stainless steel pipe dimensions.
For this size, the pipe has an outside diameter (OD) of 168.3 mm, an inside diameter (ID) of 162.76 mm, and a wall thickness of 2.77 mm. The listed pipe weight is 11.31 kg/m, while the weight including water is 32.1 kg/m.

What Is Schedule 5S Pipe?
Schedule 5S is a thin-wall stainless steel pipe schedule listed in ASME B36.19. The “S” designation is commonly used for stainless steel pipe schedules. Compared with heavier schedules, Schedule 5S provides a lighter wall thickness and lower pipe weight, which can help reduce handling effort, support load, and fabrication requirements in suitable applications.
However, pipe schedule selection should always be reviewed against design pressure, temperature, corrosion allowance, project code, and service conditions before final use.

Why DN150 Pipe Dimensions Matter
Many users search for DN150 pipe dimensions to verify piping layout, support spacing, fabrication requirements, transport limits, and compatibility with fittings or connected equipment. For this pipe size, accurate dimensions are important for spool coordination, structural checks, and installation planning.
Knowing the correct 6 inch Schedule 5S pipe dimensions also helps engineers, designers, estimators, buyers, and students compare this size with other schedules when reviewing wall thickness, internal flow area, and total pipe weight.
NPS 6 and DN150 Explained
NPS stands for Nominal Pipe Size in inches, while DN stands for Diameter Nominal in metric designation. For this pipe size:
- NPS 6 = inch-based nominal pipe size
- DN150 = metric nominal designation
Although DN is shown in metric form, the actual outside diameter should always be checked from the dimensional standard. For this size, the OD is 168.3 mm.

How to Read the 6 Inch Schedule 5S Data
The outside diameter is the principal envelope dimension used when checking clearances, supports, clamps, sleeves, and connections to other piping components. The inside diameter describes the available passage through the pipe and is relevant to flow-area comparisons and equipment-interface checks.
Wall thickness is the radial material thickness between the outside and inside surfaces. It should not be treated as a complete design-pressure qualification by itself. Design review must also consider the material specification, temperature, corrosion allowance, joining method, applicable design code, and service conditions.
Pipe Weight and Weight Including Water
The listed pipe weight represents the pipe itself, while the value identified as weight including water represents the pipe together with its stated internal water load. These values serve different purposes: pipe-only weight is useful for handling and support estimates, while the water-loaded value is more relevant to filled-pipe support, temporary conditions, and installation planning.
Actual support design should account for the complete system, including fittings, valves, insulation, contents, support spacing, operating conditions, and any project-specific load combinations. Do not use the tabulated weight as a substitute for an engineered support check.
Using the DWG Reference
The downloadable DWG can support drafting and preliminary coordination work. Before issuing a drawing or fabrication document, confirm units, layer conventions, connection details, tolerances, and project requirements against the governing dimensional reference and the approved component data.
This page also provides useful cross-reference opportunities to related PipeSTD resources on pipe dimensions, schedule comparisons, flange dimensions, fitting dimensions, and piping terminology. Linking those subjects helps readers move from a dimensional lookup to a more complete piping design workflow.
Frequently Asked Questions
What does Schedule 5S mean?
Schedule 5S identifies a thin-wall stainless steel pipe schedule. The “S” designation distinguishes stainless steel pipe schedule references from common carbon-steel schedule designations.
Are NPS 6 and DN150 the same pipe size?
NPS 6 and DN150 are nominal designations used to identify the same general pipe size in inch-based and metric terminology. Always verify the actual outside diameter from the applicable dimensional reference rather than treating the nominal designation as the measured diameter.
What is the difference between pipe weight and weight including water?
Pipe weight refers to the pipe itself. Weight including water adds the internal water load, so the two values should be used for different handling, support, and operating-condition checks.
Can the listed dimensions be used for final pipe design?
The dimensions are useful for reference, layout, estimating, and coordination. Final selection requires review of pressure, temperature, corrosion allowance, material requirements, code rules, joining details, and the actual service conditions.
What should be checked before using the DWG file?
Check the drawing units, revision status, dimensional source, connection details, and project drafting requirements. Confirm the component data before using the file for fabrication or issued-for-construction documentation.
