Schedule 10 Pipe 34 Inch Data Table
| Pipe Size | DN | OD (mm) | Wall Thickness (mm) | ID (mm) | Weight (kg/m) |
|---|---|---|---|---|---|
| 34 inch | 850 | 864 | 7.92 | 848.16 | 167.21 |
What Does Schedule 10 Mean?
Schedule 10 indicates the wall thickness series of the pipe. For the same nominal pipe size, the outside diameter remains fixed, while the wall thickness changes depending on the pipe schedule. A thicker wall generally increases pipe weight and reduces the inside diameter.
Typical Uses of 34 Inch Schedule 10 Pipe
NPS 34 Schedule 10 pipe is commonly used where large flow capacity is required with relatively lighter wall thickness than heavier schedules. It may be used in water transfer systems, low-pressure process lines, utility piping, drainage-related applications, plant layout work, and general piping design references.
Why Pipe Weight Is Important
Pipe weight per meter is useful for transport planning, support design, structural loading, fabrication estimates, and lifting calculations. In large-diameter piping systems, total line weight can significantly affect installation methods and support spacing.
34 Inch Schedule 10 Pipe Calculation Notes
The listed weight is based on standard steel pipe dimension data using the outside diameter and wall thickness of the pipe. Actual product weight may vary slightly depending on manufacturing tolerance, material specification, and supplier standard.
