Stainless steel tubes are a critical component in various industries, from construction to food processing, due to their durability and resistance to corrosion. Among the various types of stainless steel pipes, Schedule 40 is one of the most commonly used. This article will delve into the dimensions, specifications, applications, advantages, and disadvantages of stainless steel tube Schedule 40.
Schedule 40 refers to a specific wall thickness of pipes. The schedule number indicates the pipe's ability to withstand pressure; higher numbers indicate thicker walls. For stainless steel pipes, Schedule 40 is a popular choice because it balances strength and weight.
- Material Composition: Typically made from stainless steel grades like 304 or 316, which provide excellent resistance to corrosion.
- Wall Thickness: The wall thickness varies with the diameter of the pipe. For example:
- A 1-inch diameter Schedule 40 pipe has a wall thickness of approximately 0.133 inches (3.38 mm).
- A 2-inch diameter pipe has a wall thickness of about 0.154 inches (3.91 mm).
- Pressure Rating: Schedule 40 pipes can handle pressures up to about 1,000 psi, making them suitable for various applications.
The dimensions of stainless steel tubes under Schedule 40 can be summarized in the following table:
Nominal Pipe Size (NPS) | Outside Diameter (OD) | Wall Thickness | Inside Diameter (ID) |
---|---|---|---|
1/8 inch | 0.405 inches (10.3 mm) | 0.068 inches (1.73 mm) | 0.269 inches (6.83 mm) |
1/4 inch | 0.540 inches (13.7 mm) | 0.088 inches (2.24 mm) | 0.364 inches (9.25 mm) |
1/2 inch | 0.840 inches (21.3 mm) | 0.109 inches (2.77 mm) | 0.622 inches (15.8 mm) |
1 inch | 1.315 inches (33.4 mm) | 0.133 inches (3.38 mm) | 1.049 inches (26.7 mm) |
2 inch | 2.375 inches (60.3 mm) | 0.154 inches (3.91 mm) | 2.067 inches (52.5 mm) |
3 inch | 3.500 inches (88.9 mm) | 0.216 inches (5.49 mm) | 3.068 inches (77.9 mm) |
4 inch | 4.500 inches (114.3 mm) | 0.237 inches (6.02 mm) | 4.026 inches (102.6 mm) |

The versatility of Schedule 40 stainless steel tubes allows them to be used in various applications:
- Oil and Gas Industry: Transporting oil and gas under high pressure.
- Chemical Processing: Used in pipelines for transporting chemicals safely.
- Food and Beverage Industry: Ideal for sanitary applications due to their corrosion resistance.
- Construction: Used for structural support in buildings and other constructions.
- HVAC Systems: Employed in heating and cooling systems due to their durability.
Stainless steel is known for its ability to resist rust and corrosion, making it ideal for harsh environments.
The thicker walls provide strength, allowing them to withstand high pressures without deformation.
Suitable for various applications across multiple industries.
Stainless steel has a long lifespan, reducing the need for frequent replacements.
Generally more expensive than other materials like PVC or carbon steel.
Heavier than other types of pipes, which can complicate installation.
Prone to thermal expansion and contraction, which may require additional considerations during installation.
In summary, stainless steel tube Schedule 40 is a highly durable and versatile option for various industrial applications due to its strength and resistance to corrosion and pressure.
Schedule 80 pipes have thicker walls than Schedule 40 pipes, which allows them to handle higher pressures but also makes them heavier.
Yes, Schedule 40 stainless steel pipes are commonly used in plumbing systems due to their durability and resistance to corrosion.
The most common grades are *304* and *316*, with *316* offering better corrosion resistance in marine environments.
The weight can be calculated using the formula:
Weight=Length×Weight per foot
Where weight per foot varies based on the pipe size.
The maximum allowable pressure can vary based on the pipe size but typically ranges up to about *1,000 psi* for most sizes.
