Schedule 160 Pipe 4 Inch Data Table
| Pipe Size | DN | OD (mm) | Wall Thickness (mm) | ID (mm) | Weight (kg/m) |
|---|---|---|---|---|---|

What Does Schedule 160 Mean?
Schedule 160 refers to an extra heavy wall thickness series used for steel pipe under ASME B36.10. For the same nominal pipe size, the outside diameter remains fixed while the wall thickness increases according to the schedule. A much thicker wall reduces the inside diameter and significantly increases pipe weight.
Typical Uses of 4 Inch Schedule 160 Pipe
NPS 4 Schedule 160 pipe is commonly referenced for very heavy-duty industrial piping systems where extremely high wall thickness is required. It may be used in process piping, plant utility systems, support design, fabrication work, and engineering applications where pipe strength and wall thickness are more critical than maximum flow area.
Why Pipe Weight Matters
Pipe weight per meter is essential for transport planning, crane lifting studies, support design, structural loading, fabrication estimates, and installation planning. For a 4 inch Schedule 160 pipe, the extra heavy wall thickness results in much higher installed weight than lighter schedules, so accurate weight data is important for engineering and construction work.
4 Inch Schedule 160 Pipe Calculation Notes
The listed weight is based on standard steel pipe dimensions 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.
