1. What Is an API Flange?
A flange is a type of fitting that is used to connect two pieces of pipe. It is a disk-shaped piece of metal that is bolted to the ends of the pipes. The flange provides a place for the bolts to secure the pipes together.
API flanges (American Petroleum Institute) are specifically designed for use with API pipes. These pipes are designed with very competitive lead times and API flange forgings to handle oil and explosive gases.
In API vs ANSI flanges, the full line API flange standard testing requirements are much more tolerant compared to the ANSI and Wellhead flange chart. So for the petroleum industry, ASME vs API, API flange dimensions are a clear choice.
They are made from higher quality steel than standard flanges and they have a greater tolerance for alignment error. This makes them ideal for use in oil and gas pipelines.
Connection
API flange pressure temperature ratings can be used in conjunction with the API flange bolt torque chart to create a stronger connection than using a standard API flange pressure rating.
This means that they are less likely to break or leak over time and will last longer than other types of pipes.
Tolerance
API flanges have a greater tolerance for alignment error so you don’t need to be as precise when connecting them to other API flange sizes. This makes them easier to use and reduces the chances of errors occurring during installation.
Resistance
The API flange material is made from higher quality steel than standard API flange pressure rating charts so they are more resistant to wear and tear. They will last longer under repeated use without corroding or breaking.
2. Uses of API Flange
API flange weights are used in a variety of applications across many industries. Some of the most common uses of API flange torque specs include:
- Petrochemical plants
- Pipelines
- Refineries
- Power plants
- Marine applications
API flange ratings are highly versatile and can be used in a variety of applications depending on the requirements of the project. They are often chosen for their high quality and performance, as well as their durability.
When it comes to choosing the right API flange specification for your project, be sure to consult with a reliable manufacturer who can help you find the best option for your needs. Contact us at Oflange for more details!
3. Different Types of API Flange
API flange is a type of API flange dimensions chart that is specifically used in the oil and gas industry. It is a standardized flange that has been developed by the American Petroleum Institute. There are several different types of API flange, which include:
Blind Flange
A blind flange is a type of flange that does not have a bore. This means that it does not have an opening through which fluid or other material can flow.
Instead, the blind flange is used to close off an opening in a pipeline or other system. It is installed by welding it into place, and then the weld is ground down so that the flange is flush with the surface around it.
Blind flanges are commonly used in pipelines and other systems where it is necessary to seal off an opening.
They are also used in conjunction with other flanges to create more complex assemblies. Blind flanges are made from a variety of materials, including steel, stainless steel, and aluminum.
Lap Joint Flange
Lap Joint Flanges are similar to Slip-on Flanges, except that they have a lap joint feature that allows them to be joined to another flange.
The lap joint is generally a male-female joint, where the male flange has a protrusion that snaps into the female flange. The lap joint flange is commonly used in pipelines and other industrial applications.
Socket Weld Flange
Socket weld flanges are used to join pipes together. The API flange bolt pattern is placed on the end of one pipe, and the other pipe is inserted into the hole in the center of the flange. A socket weld is then performed, which joins the two pipes together.
Threaded Flange
A threaded flange is a type of API flange ruler that has screw-like protrusions on the outside diameter of the flange.
This design allows for a more secure connection between two pieces of pipe, as the screws can tighten down to create a stronger seal.
These flanges are often used in industrial settings, where a reliable seal is essential for safety and performance reasons.

4. How Do You Install API Flange?
Installing an API flange requires a few simple steps. Here are those:
Gather the Correct Tools
First, make sure that you have the correct tools for the job. You’ll need a pipe wrench, a screwdriver, and a socket wrench.
Read the Manufacturer’s Manual
Before working with API welding neck flanges, it is important to use the same pressure rating system for all the specialized or custom parts respective of their pressure classes.
The best way to do this is by referring to the API flange dimensions pdf, API flange chart download, and API flange calculator included in the instruction manual provided by the manufacturer.
Clean the Pipe Thoroughly
Once you have the proper tools, you can begin the installation process for custom products with the same dimensions. Remove the old flange and clean the pipe thoroughly.
Pipe Wrench Installation
You can install the API flange bolt chart using one of two methods. The first method is to use a pipe wrench and socket wrench to remove the old flange and install the new flange.
This method works well for small pipes with simple designs. However, if you have a larger pipe or complex design, it may be difficult to get the flange sealed up.
Socket Wrench Installation
The second method is to use a screwdriver and socket wrench. This method works well for large pipes or complex designs but can be difficult on smaller pipes. You will need both tools, as well as some patience and time!
Install the Flange and Seal It
Apply a layer of sealant to the API 6A pipe and install the new flange. Tighten the screws and bolts until they are snug. Finally, test the flange for leaks.
You may need help with installing an API flange slide rule for sale depending on the type of pipe you have.

9. API Flange Chart
The API flange chart contains information about flanges that are available in a variety of sizes, ranging from 1/2 inch to 72 inches. It can be made from a variety of materials, including carbon steel, stainless steel, and alloy steel.
10. API Flange Dimensions
API flange dimensions are standardized and specified in ANSI/ASME B16.5. The dimensions of an API flange are determined by the size of the pipe it is mating with, and the number of bolts required to securely fasten the flange to the pipe.
Bolt Pattern
The bolt pattern on an API flange, or the number and spacing of bolts around the circumference of the flange, is also standardized.
This bolt pattern is what determines the size of the flange. For example, a 2-bolt flange will have a smaller diameter than a 6-bolt flange.
Flange Size
The most common API Flange Sizes are
- 2 inches
- 3 inches
- 4 inches
- 6 inches
- 8 inches
- 10 inches
- 12 inches
The bolt hole sizes for these flanges also follow a standardized size, which is determined by the diameter of the flange.
For example, the bolt hole size for a 12-inch API flange will be approximately 11/16 inches.
Flange Thickness
The thickness of an API flange is also standardized by the API Flange Standard. The most common thicknesses are 0.25 inches, 0.375 inches, and 0.50 inches. However, thicker and thinner flanges are available upon request.
