Applications of ASME B36.10M Sch 5 Pipe
SCH5 is one of the pipe wall thickness grades, indicating a thinner wall and is suitable for low-pressure and low-temperature environments. SCH5 pipes are commonly used in the following fields:
- Low-pressure fluid transportation: Such as water, air, steam, etc.
- Chemical industry: For transporting corrosive media, usually made of stainless steel.
- Food and pharmaceutical industries: Used in sanitary piping systems.
- Construction and decoration: For lightweight structures or decorative purposes.
- HVAC systems: Used in low-pressure pipes in heating, ventilation, and air conditioning systems.
ASME B36.10M SCH5 pipes are thin-walled, economical pipes suitable for low-pressure and low-temperature environments. Correct selection and use of SCH5 pipes can significantly reduce project costs, but attention should be paid to their application range and installation requirements.

FAQ
- SCH5 pipes are suitable for low-pressure environments, and their pressure-bearing capacity depends on the pipe diameter, material, and operating temperature. Calculations should be based on standards like ASME B31.3.
- It is not recommended. SCH5 pipes have a thin wall, and their strength and pressure capacity significantly decrease at high temperatures. It is better to choose pipes with higher wall thickness grades, such as SCH40 or SCH80.
- Common materials include carbon steel (e.g., ASTM A106), stainless steel (e.g., ASTM A312), and alloy steel (e.g., ASTM A335).
Installation precautions include:
- Avoid excessive mechanical stress.
- Use proper supports and fixing devices.
- Control heat input during welding to prevent deformation.
The main differences are in wall thickness and pressure capacity:
- SCH5 has a thinner wall and is suitable for low-pressure environments.
- SCH40 has a thicker wall and is suitable for medium to high-pressure environments.
Corrosion resistance depends on the material:
- Carbon steel SCH5 pipes need corrosion protection (e.g., painting or galvanizing).
- Stainless steel SCH5 pipes have better corrosion resistance.
When selecting, consider:
- Operating pressure and temperature.
- Nature of the medium (e.g., corrosive).
- Installation environment and budget.
