Schedule 10, referred to as SCH 10, is a standard for measuring the wall thickness of steel pipes. SCH 10 is more common in medium and low pressure fluid piping systems.
Schedule 10 Pipe(sch 10)
The pipe wall thickness specified in SCH10 is not a specific value, but a series of pipe wall thicknesses. The specific wall thickness varies according to the change in nominal pipe diameter.
For example:
- 1/2-inch pipe: OD 0.840-inch, wall thickness 0.065-inch
- 2-inch pipe: OD 2.375-inch, wall thickness 0.083-inch
- 6-inch pipe: OD 6.625-inch, wall thickness 0.134-inch
But they all follow the ASME B36.10/B36.19 standards, which define the size standards for carbon steel pipes and stainless steel pipes.

Sch 10 Wall Thickness Selection
Before you choose SCH10, please note the following points
- Pressure bearing capacity: SCH10 has a relatively thin wall thickness, and its pressure resistance is relatively weak, generally not exceeding 0.6MPa (about 87psi), and can only be used in low-pressure environments.
- Fluid requirements: If the fluid is corrosive, stainless steel or alloy materials are preferred.
- Temperature: SCH is not suitable for working in extreme temperatures and is usually used in normal temperature environments.
FAQs
What is the difference between SCH10 and SCH10S?
SCH10S is specifically for stainless steel pipes; SCH10 is suitable for carbon steel and stainless steel, but the wall thickness calculation standards for both are the same
Does SCH10 pipe require special treatment under low temperature conditions?
When used in an environment below -29℃, carbon steel SCH10 needs to undergo Charpy impact test
