Contrary to all the flange types seen above, blind flanges do not have a center hole, and are used to blind or seal a pipeline, a valve/pressure vessel and block the flow of the fluid.
Blind flanges have to withstand remarkable mechanical stress due to the system pressure and the required bolting forces. Blind flanges allow easy access to the pipeline, as they can be easily unbolted to let the operator execute activities inside the terminal end of the pipe (this is also the reason why the blind flange type is used as a manhole for pressure vessels, at times). It is maybe interesting to observe that, while this flanges type is easier to manufacture, they are sold at a premium average cost per kilogram compared to the other flange types.

Frequently Asked Questions

Most frequent questions and answers

What is slip-on flanges?

Slip-on flanges, also known as SO flanges, are a type of pipe flange that is designed to be slipped over the end of a pipe and then welded in place. They are typically used in low-pressure piping systems and are a cost-effective alternative to other types of flanges such as weld neck flanges or threaded flanges. Slip-on flanges are typically used in applications where a smooth bore is required, as the inside of the flange is smooth and does not have any raised or recessed areas. They are also easy to install, as they do not require any special tools or equipment.

Do slip-on flanges have a raised face?

A raised or flat face is frequently included with slip-on pipe flanges. Slip-on pipe flanges under 400# are often required to have a raised face, which is typically 1/16″ high.

How are slip-on flanges made?

Slip-on flanges are typically made using one of two methods: forging or casting.

  1. Forging: Slip-on flanges can be forged from a piece of metal, such as carbon steel or stainless steel. The metal is heated to a high temperature and then shaped into the desired shape using a press or hammer. This method results in a flange that is strong and durable.

  2. Casting: Slip-on flanges can also be cast from a molten metal, such as aluminum or bronze. The molten metal is poured into a mold and then allowed to cool and solidify. This method results in a flange that has a consistent and uniform shape, but may not be as strong as a forged flange.

Both methods have their own advantages and disadvantages, it’s up to the manufacturers or the application which method to use. Slip-on flanges can also be machined, this is usually done when the flange is to be used in a specific application and when the flange needs to have a specific feature that can’t be obtained by the forging or casting method.

After the flange is made, it will go through a process of machining, polishing, and cleaning to make sure it meets the standards and specifications.

What is the hub of a slip-on flange?

To support more pressure, a slip-on hub flange incorporates a separate component called a “hub.” The slip-on flange with the hub is frequently used for pipes with greater pressures and/or bigger diameters than the slip-on flange without the hub.

How do slip-on flanges work?

Slip-on flanges work by being slipped over the end of a pipe or fitting and then being attached by welding or bolting. They are used to connect two sections of pipe or a pipe to a fitting, such as a valve or pump. The flange has a circular shape with a central hub that is the same size as the pipe, and an outer circumference that is slightly larger than the pipe. It is then attached to the pipe or fitting to create a strong and sealed connection, while also providing a surface for attaching other components such as gaskets. The proper installation is essential to ensure compatibility with the pipe or fitting and to prevent leaks.

What are the common materials used for slip-on flanges?

Slip-on flanges can be made from a variety of materials, including carbon steel, stainless steel, alloy steel, aluminum, and bronze. The choice of material will depend on the application and the required strength and corrosion resistance.

What are the advantages of using slip-on flanges?

Slip-on flanges are easy to install, do not require any special tools or equipment, and are a cost-effective solution for low-pressure systems. They also have a smooth bore, which is ideal for applications where a smooth inside surface is required.

What are the disadvantages of using slip-on flanges?

Slip-on flanges are not suitable for high-pressure systems as they may not have the strength and durability of other types of flanges. They also require the pipe or fitting to be perfectly prepared and cleaned before installation to ensure a proper seal.

How are slip-on flanges installed?

Slip-on flanges are installed by slipping the flange over the end of the pipe or fitting and then welding or bolting it in place. The pipe or fitting must be properly prepared and cleaned before installation to ensure a proper seal.

How are slip-on flanges maintained?

Slip-on flanges must be inspected regularly for signs of wear, corrosion, or leaks. Any damaged or worn parts should be replaced immediately. The flanges should also be kept clean and free of debris to ensure proper operation.
