ASA flanges are a popular choice in the world of piping. But what are they? And why are they so popular?

ASA flanges are some of the most popular types of flanges used in business. They’re strong and durable, making them perfect for high-pressure applications. 

In this guide, we’ll answer those questions and more. We’ll also provide a comprehensive overview of ASA flanges, including their specs, features, and benefits. By the end of this guide, you’ll know everything you need to know about ASA flanges! So let’s get started.

1. What Is an ASA Flange

An ASA flange is a type of flange that is made from aluminum and has an aluminum alloy body. It is a popular choice for high-pressure applications, thanks to its strength and durability. ASA flanges are available in a variety of sizes, and they have several features and benefits that make them a popular choice for businesses. It also comes in different class such as ASA 150 flange and ASA 300 flange.

ASA flanges are named for the American Standards Association, which standardized them in 1938. ASA flanges can also be referred to as ANSI flanges since they are based on a standard that was created by the American National Standards Institute (ANSI).

The most popular type of ASA vacuum flange is made from aluminum alloy 300. This material is strong andcorrosion-resistant, which makes it perfect for high-pressure applications.

2. Uses of ASA Flange

There are many different applications for ASA flanges. Some of the most common uses include:

Pipe Connections

Pipe connections are one of the most common uses for ASA flanges. The flange allows for a secure connection between two pipes, which can then be used to transport fluids or gases. This is a very common application in industries like construction and manufacturing.

Manifold Assemblies

A manifold assembly is a device that allows multiple pipes to be connected to a single source. This can be useful in applications where there is a need to regulate the flow of fluid or gas through multiple pipes.

Valve and Pump Attachments

When a valve or pump is attached to a pipe, it needs to be secured in place. This is often done using an ASA flange. This allows the valve or dry scroll vacuum pumps to be easily removed when needed, without having to disconnect the entire pipe.

Instrumentation Fittings

They are often used in conjunction with valves, pumps, and other instruments to allow for easy installation and removal. Additionally, they can help to protect the instruments from damage.

Therefore, we can say that there are many different uses for ASA vacuum flanges. They are used in a wide variety of applications, from fluid and gas transportation to instrumentation fittings.

3. How Do I Identify an ASA Flange

An ASA flange is a type of flange that is used in the piping and plumbing industries. It is important to be able to identify an ASA flange, as it is a common type of flange. Here are some ways to identify an ASA flange:

Look for the Letter “A” on the Flange

One way to identify an ASA flange is to look for the letter “A” on the flange. The letter “A” is stamped on the flange to indicate that it is an ASA flange.

Check To See if the Flange Has Three Holes

Another way to identify an ASA flange is to check to see if the flange has three holes. ASA flanges have three holes, while other types of flanges may have fewer or more holes.

Notice the Thickness of the Flange

The thickness of the ASA flange is another indication that you are dealing with an ASA flange. The wall thickness of an ASA flange will usually be between 0.15 inches and 0.25 inches thick, while other flange types may have a different wall thickness range.

Check the Size of the Flange

The size of the flange is another way to identify an ASA flange. For example, if you are looking for a specific size of an ASA flange, such as one that is 14 inches in width and 18 inches in height, then it will be easy to identify when compared to other types of flanges.

Look at Its Color

ASA flanges are also easy to identify by their color. ASA flanges are typically a light gray color, which makes them easily distinguishable from other types of flanges.

By using any of these methods, you should be able to determine whether or not you are dealing with an ASA flange. If you have any questions about identifying a specific type of flange, please contact Oflange for assistance.

4. Dimensions of an ASA Flange

An ASA flange is a type of flange that is used in the piping industry. It is made of aluminum and is designed to be used with a steel pipe.

The dimensions of an ASA flange are as follows:

Flange Diameter	4 inches
Flange Thickness	0.25 inches
Bolt Circle Diameter	5.125 inches
Number of Bolts	8

The purpose of the dimensions is to make it compatible with standard pipe sizes and ASA fittings. The dimensions are also designed to provide a strong, reliable connection between the two components.

It is important to note that the hole size may vary depending on the application, and should be checked before the purchase.

5. ASA Flange Sizes

ASA flange sizes can vary greatly, depending on the application. In general, the sizes range from 1/2 inch to 24 inches. However, there are some exceptions. For instance, the largest ASA flange size is 36 inches.

ASA flange sizes are determined by the pipe size and the pressure rating. Generally, the pipe size will be a multiple of 2 inches. So, a 6-inch pipe will have an ASA flange size of 12 inches. The pressure rating will also affect the size of the ASA flange. A higher pressure rating will require a larger ASA flange.

ASA flanges are used in many industries. Some of the more common applications include oil and gas; power generation; water treatment; petrochemical processing; transportation infrastructure, etc. As you can see, there is no single application that requires ASA flange sizes to be specified to a particular size or pressure rating.

6. ASA Flange Standard

ASA Flange Standard is an American Society of Mechanical Engineers (ASME) standard that covers the design and manufacture of flanges made from wrought materials such as carbon steel, stainless steel, and alloys.

This standard is important because it helps ensure that flanges are manufactured to a high quality and are safe to use. The standard was first published in 1937 and has been updated many times since then.

ASA flange standard is one of the most widely used standards for welding pipe flanges and ASA fitting. It covers a wide range of applications, from low-pressure systems to high-pressure systems up to 15,000 psi (103 bar).

The standard also includes provisions for studding and bolting flanges together. The American Society of the Association (ASA) has developed a flange standard that is now commonly used in the United States.

This standard is known as ASA B16.5 and it covers various aspects of flanges, such as their dimensions, tolerances, and markings. Flanges that meet the ASA B16.5 standard are typically made from forged steel, although other materials may also be used.

To comply with the standard, flanges must meet certain dimensional requirements, including thickness, diameter, and hole spacing. They must also conform to certain tolerances about their size and shape.

Flanges that meet the ASA B16.5 standard are typically marked with the manufacturer’s name or logo, as well as the pressure rating for which they are designed. They may also include other information such as a material grade or certification mark.

7. ASA Flange Cost

When it comes to ASA flanges, there is no one-size-fits-all answer to the question of how much they cost. The price of an ASA flange can vary depending on several factors, such as the size and type of flange, the material it is made from, and the manufacturer.

That said, some general trends can give you a rough idea of what to expect. For smaller flanges (up to 24 inches), the cost is generally in the range of $50 to $150. Larger flanges tend to be more expensive, with prices ranging from $200 to $1,000 or more.

The most expensive ASA flanges are typically made from specialty materials such as titanium orInconel, while the cheapest flanges are often made from cast iron. It is important to keep in mind that these prices are just a general guideline.
