Difference Between Code 61 And 62 Flanges

Do you ever find yourself wondering what the differences are between code 61 and 62 flanges? If so, you’re not alone! In this blog post, we’ll take a look at the differences between the two types of flanges, their applications and which type of flange is best suited for your project.

We’ll also discuss the benefits and drawbacks of each type of flange. By the end of this article, you’ll have a better understanding of the differences between code 61 and 62 flanges and be able to choose the right type of flange for your project.

The key differences between code 61 and code 62 flanges

The key differences between code 61 and code 62 flanges

The difference between Code 61 and Code 62 flanges may seem insignificant, but in fact, there are several key differences between the two. Code 61 flanges are designed for higher pressure applications, with a maximum working pressure of 1500 psi. On the other hand, Code 62 flanges have a lower working pressure, with a maximum of 750 psi.

On the other hand, Code 62 flanges have a lower working pressure, with a maximum of 750 psi. Furthermore, Code 61 flanges are designed with a thicker wall than Code 62 flanges. This difference in wall thickness translates to greater strength and durability for Code 61 flanges.

Lastly, Code 61 flanges are designed for use with thicker pipe joints than Code 62 flanges. All of these differences between the two flange types should be taken into consideration when selecting the right type of flange for a given application.

The connection type for code 61 and code 62 flanges

The connection type for code 61 and code 62 flanges

The difference between code 61 and code 62 flanges is the connection type. Code 61 flanges use a slip-on connection, meaning that the flange simply slides over the pipe. On the other hand, code 62 flanges require a welded connection, meaning that the flange needs to be welded to the pipe.

This makes code 62 flanges stronger and more durable than code 61 flanges.

The pressure rating for code 61 and code 62 flanges

The pressure rating for code 61 and code 62 flanges

When it comes to flange pressure ratings, understanding the difference between code 61 and code 62 flanges is essential. Code 61 flanges are rated for a maximum operating pressure of 1500 PSI while Code 62 flanges are rated for a maximum operating pressure of 2500 PSI. This means that when it comes to flange pressure ratings, Code 62 flanges are much higher and can handle greater pressure loads than Code 61 flanges.

This means that when it comes to flange pressure ratings, Code 62 flanges are much higher and can handle greater pressure loads than Code 61 flanges. Furthermore, Code 62 flanges are designed to have a higher burst pressure rating, allowing them to withstand sudden pressure increases without failing. This makes them ideal for applications that require high-pressure ratings and burst pressure ratings.

The material specifications for code 61 and code 62 flanges

The material specifications for code 61 and code 62 flanges

The difference between code 61 and code 62 flanges is in the material they are made of. Code 61 flanges are made of carbon steel, whereas Code 62 flanges are made of stainless steel. Carbon steel is a much more affordable material than stainless steel, so Code 61 flanges are generally the more cost-effective option.

Carbon steel is a much more affordable material than stainless steel, so Code 61 flanges are generally the more cost-effective option. However, stainless steel is much more resistant to corrosion and rust, so Code 62 flanges are the better choice for more demanding applications. Both types of flanges are widely used in the oil and gas industry, but Code 62 flanges are better suited for more corrosive environments.

The applications for code 61 and code 62 flanges

The applications for code 61 and code 62 flanges

When it comes to piping systems, the choice of flange is an important factor in ensuring a successful installation. Code 61 and Code 62 flanges are two commonly used types of flanges for these applications. While they share some similarities, there are some key differences between the two that should be taken into consideration.

While they share some similarities, there are some key differences between the two that should be taken into consideration. Code 61 flanges are used for moderate pressure applications, while Code 62 flanges are designed to handle high-pressure systems. Additionally, Code 61 flanges have a higher temperature rating than Code 62 flanges, making them better suited for applications with higher temperatures.

Furthermore, Code 61 flanges have a larger bore size than Code 62 flanges, allowing for a greater flow of fluid. These differences should be taken into account when selecting the right flange for any application.


Final Touch

In conclusion, the main difference between Code 61 and Code 62 flanges is the size of their hub and bolt circle. Code 61 flanges are typically smaller, with a hub diameter of 45 inches and a bolt circle diameter of

75 inches, while Code 62 flanges have a larger hub diameter of 31 inches and a bolt circle diameter of

25 inches. Additionally, Code 61 flanges are most commonly used in low pressure and low temperature applications, while Code 62 flanges are suitable for higher pressure and higher temperature applications.
