SANS/ SABS 1123 Flanges

Understanding your choice of SANS/ SABS 1123 flanges options

SANS (South African National Standard) and SABS (South African Bureau of Standards) are standards organizations based in South Africa that develop and maintain technical standards for various industries, including the manufacturing of flanges.
SANS/SABS 1123 is a standard for flanges that specifies various dimensions, materials, and pressure ratings for flanges used in piping systems.
When choosing SANS/SABS 1123 flanges, it’s important to consider factors such as the type of fluid or gas being transported, the pressure and temperature of the system, and the compatibility of the flange material with the pipe material.

What are SANS/ SABS 1123 flanges?

SANS/ SABS 1123 flanges are a type of standardized flange used in South Africa for connecting pipes and equipment in industries where reliability, safety, and durability are essential.

What are the different types of SANS/ SABS 1123 flanges?

Flanges come in many different types and styles, but some common types of SANS/ SABS 1123 flanges include:

Types of SANS/ SABS 1123 flanges

It’s critical to be aware of the various flange types available to you if you’re in the market for some. A standard known as SANS/ SABS 1123 details the five primary types of flanges that are required in South Africa.
Welding Neck Flange
A welding neck flange is a type of flange that has a long, tapered hub that is welded to the pipe. This flange is designed to be used with butt-welded pipe connections and is known for its strength and durability. The long neck on this flange provides a smooth transition from the pipe to the flange and helps to reduce turbulence and erosion in the pipeline.
Slip-On FF Flange
A slip-on FF (flat face) flange is a type of flange that slips over the end of the pipe and is then welded in place. This flange is easy to install and is often used in applications where the piping system needs to be disassembled and reassembled frequently. The flat face on this flange provides a smooth surface for the gasket to seal against.
Threaded Screwed Flange
A threaded screwed flange is a type of flange that has threads on the inside diameter of the flange. This flange is screwed onto the pipe and is used in applications where it is necessary to disassemble and reassemble the piping system frequently. The threads on this flange provide a secure connection between the pipe and the flange.
Slip-On Bossed Flange
A slip-on bossed flange is a type of flange that has a raised section, or boss, that extends from the flange face. This flange is used in applications where the piping system needs to be easily disassembled and reassembled. The raised boss on this flange provides additional support to the pipe and helps to prevent it from slipping out of the flange.
Blind Flange
A blind flange is a type of flange that is used to close the end of a piping system. This flange is often used when a piping system needs to be tested or when a section of the pipeline needs to be isolated. The blind flange is designed to be bolted onto the end of the pipe and has no opening or bore.
Each type of SANS/ SABS 1123 flange has its own unique characteristics and is best suited for certain applications. When selecting a flange, it’s important to consider factors such as the type of piping system, the pressure and temperature of the system, and the frequency with which the system needs to be disassembled and reassembled. By understanding the different types of flanges available, you can make an informed decision about which one is the best fit for your project.

Advantages and disadvantages of SANS/ SABS 1123 flanges

Flanges are an essential component in piping systems used to connect pipes, valves, and other equipment. The SANS/ SABS 1123 flange is a South African standard used in a wide range of industries. While these flanges have their advantages, they also come with some disadvantages. In this post, we will discuss both the advantages and disadvantages of SANS/ SABS 1123 flanges.

SANS/ SABS 1123 flanges have both advantages and disadvantages. They are durable, cost-effective, and easy to install, making them an ideal choice for many industries. However, they are limited in availability, restricted in use, heavier, susceptible to corrosion, and lack flexibility. Companies should consider these factors before choosing SANS/ SABS 1123 flanges for their piping systems.

Flange Face Finish

Flange face finish is a crucial factor in ensuring proper sealing between flange connections. There are several types of flange face finishes available, each with its unique characteristics and benefits.
Types of Flange Face Finish
One type of flange face finish is the serrated finish. This finish is created by machining a series of grooves into the flange face, providing better grip and improved sealing when compressed. Serrated finishes are commonly used in applications where the flange connection may be subject to vibration or movement.
Another type of flange face finish is the stock finish. This is the default finish provided by the manufacturer, and it typically has a smooth surface. While it may not offer the same grip as a serrated finish, a stock finish is suitable for many standard applications.

Spiral serrated finishes feature a spiral pattern of grooves that helps to distribute stress evenly across the flange face. This can help to prevent damage and distortion, which can lead to leaks or other issues.

Concentric serrated finishes are similar to spiral serrated finishes but feature a series of concentric rings around the flange face. This pattern can provide enhanced sealing and grip compared to other types of serrated finishes.

Finally, a smooth finish is another option for flange face finish. Smooth finishes are often used in applications where the flange connection is not subject to significant movement or vibration. While it may not offer the same grip as a serrated finish, a smooth finish can still provide a reliable seal in many standard applications.

For example:

Machining of gasket faces of flanges to a smooth finish of Ra = 3.2 – 6.3 micrometer (= 125 – 250 microinches AARH)

• AARH stands for Arithmetic Average Roughness Height. It is used to measure the roughness (rather smoothness) of surfaces. 125 AARH means 125 micro inches will be the average height of the ups and downs of the surface.
• 63 AARH is specified for Ring Type Joints.
• 125-250 AARH (it is called smooth finish) is specified for Spiral Wound Gaskets.
• 250-500 AARH (it is called stock finish) is specified for soft gaskets such as NON Asbestos, Graphite sheets, Elastomers etc. If we use smooth finish for soft gaskets enough “biting effect” will not occur and hence the joint may develop leak.
• Sometimes AARH is referred also as Ra which stands for Roughness Average and means the same.

Selecting the appropriate flange face finish is essential to ensuring a proper seal between flange connections. Whether you choose a serrated finish, stock finish, spiral serrated, concentric serrated, or smooth finish, it is important to consider the specific application and potential stresses that the flange connection may face. By selecting the right finish for the job, you can help to prevent leaks and other issues that can lead to costly downtime and repairs.
