Stainless steel pipe is widely used in various applications due to its durability, strength and corrosion resistance. When selecting stainless steel pipes, an important factor to consider is the specification of the pipe material, that is, the wall thickness. Two common gauges of stainless steel pipe are sch 10 and sch 40. In this article, we will explore the difference between sch 10 and sch 40 stainless steel pipe along with their properties and applications.
sch 10 stainless steel pipe
Sch 10 stainless steel pipe is a stainless steel pipe with a wall thickness of 0.109 inches. It is typically used in applications requiring low voltage and non-critical applications. Some of the most important properties of sch 10 stainless steel pipe include:
- Wall Thickness: Compared to other wall thicknesses, this stainless steel tubing has a relatively thin wall thickness, making it suitable for low pressure applications.
- Pressure Rating: Rated up to 175 psi, which makes it suitable for non-critical applications.
- Aesthetic Appeal: Has a polished finish and is often used in decorative applications such as architecture or interior design.
Sch 10 stainless steel pipe is commonly used in applications such as water supply lines, drainage systems, and decorative applications.
Sch 40 Stainless Steel Pipe
Sch 40 Stainless Steel Pipe is a type of stainless steel pipe with a wall thickness of 0.154 inches. It is commonly used in applications requiring high voltage and critical applications. Some of the most important properties of sch 40 stainless steel pipe include:
- Wall Thickness: The wall thickness is relatively thick compared to other steel pipes, so it is suitable for high pressure applications.
- Pressure Rating: Rated up to 1,000 psi, which makes it suitable for critical applications.
- Durability: Very durable and unbreakable, suitable for industrial applications.
Sch 40 stainless steel tubing is commonly used in applications such as chemical processing, oil and gas production, and industrial equipment.
Comparison of sch 10 and sch 40 stainless steel pipe
The main difference between sch 10 and sch 40 stainless steel tubing is their wall thickness and pressure rating. Compared with sch 40 stainless steel pipe, this sch 10 stainless steel pipe has thinner wall thickness and lower pressure rating. This makes sch 10 stainless steel tubing suitable for low pressure and non-critical applications and sch 40 stainless steel tubing for high pressure and critical applications.
Another difference between sch 10 and sch 40 stainless steel pipe is their cost. Sch 40 stainless steel pipe is generally more expensive than sch 10 stainless steel pipe because of its thicker wall and higher pressure rating.
When selecting stainless steel tubing, it is important to consider the specific requirements of the application. For non-critical applications requiring low pressure, sch 10 stainless steel tubing may be a suitable choice. For critical applications requiring high pressure, sch 40 stainless steel tubing may be required.
What other factors need to be considered when selecting stainless steel pipe?
In addition to schedule, there are several other factors to consider when selecting stainless steel pipe. Here are some of the most important factors to consider:
- Material grades: There are different grades of stainless steel pipe, each with its own unique properties and applications. The most common grades of stainless steel used for piping are 304, 316, and 317, which offer varying levels of corrosion resistance, strength, and heat resistance.
- Diameter and Length: The diameter and length of the tubing will depend on the specific application. Larger diameter pipes are generally used for high volume applications, while smaller diameter pipes are used for small volume applications. The length of the pipe will depend on the distance between the two points the pipe needs to connect.
- Wall Thickness: The wall thickness of the pipe depends on the pressure and temperature requirements of the application. Thick-walled pipes can withstand higher pressures and temperatures, while thin-walled pipes are suitable for lower pressures and temperatures.
- End Connections: The end connections of the pipe will depend on how the pipe needs to be connected to other components in the system. Common end connections include threaded, flanged and welded connections.
- Corrosion Resistance: The level of corrosion resistance required will depend on the specific application. For applications involving exposure to corrosive substances, such as the chemical processing industry, a high level of corrosion resistance is necessary.
- Cost: The cost of the pipe will depend on the material grade, diameter, length, wall thickness and end connections. It is important to consider cost when selecting tubing as it can vary widely depending on the specific requirements of the application.
In conclusion
Sch 10 and sch 40 stainless steel tubing are two common types of stainless steel tubing used in a wide variety of applications. By understanding the differences between sch 10 and sch 40 stainless steel pipe, their properties and applications, you can choose the proper pipe type for your specific needs. Whether you need thin wall low pressure pipe like sch 10 or heavy wall high pressure pipe like sch 40, there is a stainless steel pipe table for your application.
