Schedule 10 Pipe 2 Inch Data Table
| Pipe Size | DN | OD (mm) | Wall Thickness (mm) | ID (mm) | Weight (kg/m) |

What Does Schedule 10 Mean?
Schedule 10 refers to 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 schedule. A thicker wall generally increases pipe weight and reduces the inside diameter.
Typical Uses of 2 Inch Schedule 10 Pipe
NPS 2 Schedule 10 pipe is commonly used in utility systems, water lines, low-pressure process piping, drainage applications, and general fabrication work where a lighter wall thickness is suitable. It is also a practical reference size for material takeoff, support planning, and piping layout.
Why Pipe Weight Matters
Pipe weight per meter is important for transport planning, support design, structural loading, fabrication estimates, and lifting calculations. Even in smaller piping systems, installed weight can affect support spacing, handling methods, and project cost.
2 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 grade, and supplier standard.

How to Read the 2 Inch Schedule 10 Pipe Data
The pipe designation combines a nominal size with a schedule. NPS 2 identifies the nominal pipe size, while DN50 is the corresponding metric designation used on many international drawings and equipment documents. Neither label should be treated as a direct measurement of the pipe’s outside or inside diameter.
For this entry, the outside diameter is the fixed dimensional reference used to identify the pipe size. The wall thickness describes the material between the outside and inside surfaces, and the listed inside diameter is the resulting clear internal dimension. These values are especially useful when checking clearances, preparing CAD details, coordinating fittings, or reviewing a piping layout.
Schedule, Weight, and Design Coordination
Schedule is a wall-thickness series rather than a complete description of a pipe’s pressure capability. A design check may also require the material specification, manufacturing method, temperature, service conditions, joining method, corrosion allowance, and governing design code. The schedule designation alone should not be used to approve a piping system.
The listed mass per meter supports material takeoffs, transport estimates, support-load checks, lifting plans, and fabrication planning. When a line is filled, the water-filled value provides a separate coordination reference. Actual supplied mass can vary with manufacturing tolerances and product requirements, so procurement and final engineering checks should use the applicable project documentation.

Additional Questions About 2 Inch Schedule 10 Pipe
Is NPS 2 the same as a measured 2 inch outside diameter?
No. NPS is a nominal pipe-size designation. The actual outside diameter is the dimensional value shown in the reference data.
Does Schedule 10 by itself define the pipe material?
No. Schedule identifies a wall-thickness series. The material grade, manufacturing requirements, and applicable product specification must be confirmed separately.
Why are both dry and water-filled weights useful?
The dry pipe weight assists with material and handling estimates, while the water-filled figure helps coordinate installed loading when the line contains water.
Can the listed dimensions be used to select a pressure-rated system?
Dimensions are an important starting point, but pressure-system selection requires a complete engineering review of service conditions, materials, joining details, code requirements, and project specifications.
