Reducing Flanges

Understanding your choice of reducing flanges options

Your choice of reducing flanges can make or break your project. Some engineering applications require a specific type of reducing flange. In addition, in some applications, only a specific type of reducing flange will work: for example, a 4 in reducing flange. Replacing that reducing flange size with another size, such as a 3.5-inch reducing flange, can result in serious safety hazards for the project.
In this article, we will explain the differences between the various reducing flanges, and we will also discuss the various types of reducing flanges and their uses. Hopefully, this information will guide you in making an informed decision to find the right reducing flange.

What are reducing flanges?

Reducing flanges are a type of flange that connects pipes of different sizes. They have a larger diameter on one side and a smaller diameter on the other side, allowing them to fit pipes with different diameters. A reducing flange joint consists of a reducing flange and a standard flange and functions as a reducing fitting. As shown in Figure 1, the larger end of the reducing flange A, which is in contact with the standard flange B, is known as “the size from which the reduction is made”; the smaller end of the reducing flange A, which is welded to a pipe, is known as “the size to which the reduction is made.” The flow should be from the smaller size to the larger. If the flow direction were reversed, severe turbulence could occur.

Figure-1: A Reducing Flange Connection: Reducing WN Flange A and Standard WN Flange B.
As shown in Figure 1, the reducing flange is generally constructed in 3 sections: i – flange face, ii – flange thickness, and iii – flange hub. Its characteristics are obvious: the face dimensions, thickness, bolt dimensions, and outside diameter of the reducing flange are the same as those of the standard flange of the size from which the reduction is made. The hub dimensions and the bore diameter of the reducing flange are generally the same as those of the standard flange of the size to which the reduction is made.

Designation of reducing flanges

Reducing flanges are designated by NPS for each port. Two examples are given below:

• 8″ × 3″ SCH40 ASME B16.5 Class 300 weld neck flange, RF. Flange thickness, bolt dimensions, and raised face dimensions shall be supplied as per 8″ Class 300 weld neck flange. Hub diameter, weld end dimensions, bore diameter, and hub height shall be supplied to 3″ of Class 300 Weld Neck Flange.
• 8″ × 2″ Class 150 Reducing Flange, RF. Use standard 8″ Class 150 blind flange tapped to NPS 2 cone pipe thread in accordance with ASME B1.20.1.

Benefits of reducing flange

Here are some of the benefits of using reducing flanges in piping systems:

Improved Flow Control

Reducing flanges allow for better flow control in piping systems by reducing the diameter of the pipe. This helps to regulate the flow of fluids or gases and can prevent blockages and other issues.

Cost Savings

Reducing flanges can help to reduce the cost of piping systems by allowing pipes of different sizes to be connected without the need for expensive adapters or other fittings.

Easy Installation

Reducing flanges are easy to install and can be used in a variety of piping systems.

Types of Reducing Flanges

Reducing flanges manufactured to ASME B16.5 are available in Class 150 to 2500. The face of the reducing flange shall be the same as that of the mating standard flange. Reducing flanges come in different types, each with its own unique features and benefits. Here are some of the most common types of reducing flanges:

Weld Neck Reducing Flanges
Weld neck reducing flanges are the most popular type of reducing flanges due to their strength and durability. They have a long tapered hub that gradually merges into the pipe, making them ideal for high-pressure and high-temperature applications. Weld neck reducing flanges are also suitable for applications that require frequent disassembly and reassembly, as they are easy to align and weld.
Slip-On Reducing Flanges
Slip-on reducing flanges are a cost-effective alternative to weld neck reducing flanges, as they are easier to install and require less labor and time. They have a slightly larger diameter than the pipe, allowing them to slide over the pipe and connect to it by welding or bolting. Slip-on reducing flanges are ideal for low-pressure and low-temperature applications and can be used in systems that require frequent disassembly and reassembly.
Threaded Reducing Flanges
Threaded reducing flanges have a threaded hub that allows them to connect to pipes without welding or bolting. They are easy to install and disassemble and are suitable for low-pressure and low-temperature applications. Threaded reducing flanges are also ideal for frequent disassembly and reassembly applications.
Socket Weld Reducing Flanges
Socket weld reducing flanges are similar to slip-on reducing flanges but have a socket-weld connection instead of a slip-on connection. They are easy to install and disassemble and are suitable for low-pressure and low-temperature applications. Socket weld reducing flanges are also ideal for applications that require frequent disassembly and reassembly.

The welding neck reducing flange must be fitted with a hub, and the hub dimensions must be the same as those of the standard flange of the size to which the reduction is being made. Reducing flanges of the threaded, slip-on, or socket welding type may be supplied with or without a hub. The hub dimensions must be at least the same as those of the standard flange of the size to which the reduction is being made. The hub may be larger or omitted, as shown in the table below.

*Size A	*Size B
1″	1/2″
1-1/4″	1/2″
1-1/2″	1/2″
2″	1″
2-1/2″	1-1-4″
3″	1-1-4″
3-1/2“	1-1/2″
4″	1-1/2″
5″	1-1/2″
6″	2-1/2″
8″	3″
10″	3-1/2″
12″	3-1/2″
14″	3-1/2″
16″	4″
18″	4″
20″	4″
24″	4″

*Size A: Nominal pipe size of the larger end of a reducing flange; Size B: The smallest NPS for the smaller end of a reducing flange requiring a hub.
If the “smaller end” (reducing outlet) of the flange is smaller than those listed in the “Size B” column, the reducing flange can be supplied without a hub (made from a blind flange). Class 150 reducing flanges have no counterbore. Class 300 and higher pressure reducing flanges have a counterbore depth Q of 7 mm for tappings in NPS 2 and smaller and 9.50 mm for tappings in NPS 21∕2 and larger. The diameter Q of the counterbore is the same as that given in the threaded flange tables for the corresponding tapping.

Standard for Reducing flanges

The most common standards for reducing flanges are the American National Standards Institute (ANSI), the American Society of Mechanical Engineers (ASME), and the International Organization for Standardization (ISO).
ANSI Standard for Reducing Flanges
The ANSI Standard for reducing flanges is an industry-standard that defines the dimensions, materials, and pressure ratings of reducing flanges. ANSI B16.5 is the most commonly used standard for reducing flanges in the United States. The standard covers flanges from ½ inch to 24 inches in diameter.
ASME Standard for Reducing Flanges
The ASME Standard for reducing flanges is another widely used standard for reducing flanges. The ASME B16.47 is the standard for large diameter flanges while ASME B16.48 covers the dimensions for smaller reducing flanges. The ASME standard specifies dimensions and materials in metric and imperial units.
ISO Standard for Reducing Flanges
The ISO Standard for reducing flanges is an international standard that specifies the dimensions, materials, and pressure ratings of reducing flanges. The ISO 7005-1 standard covers the dimensions and pressure ratings of reducing flanges.

Dimensions of Reducing flanges

The dimensions of reducing flanges, including the flange size, pressure rating, bolt circle diameter, and the number and size of bolt holes.

• The diameter of a reducing flange is specified as the outside diameter of the flange. This diameter is typically larger than the diameter of the pipe being connected. The thickness of the flange is also specified, and it varies depending on the pressure rating of the flange.
• The bolt hole size is specified as the diameter of the bolt holes around the perimeter of the flange. The number of bolt holes and their spacing is also specified.
• The raised face dimensions are specified as the height of the raised face and the width of the contact surface. The raised face provides a surface for the gasket to seal against, and the contact surface’s width determines the gasket’s width that can be used.

Manufacturing process of Reducing flanges

Reducing flanges can be produced by forging, casting. We mainly produce flanges by forging, cutting and rolling processes. We will take you through the step-by-step process of manufacturing reducing flanges, from the materials used to the final product.

Step 1: Material Selection
The first step in our manufacturing process is material selection. We use only the highest quality materials, including carbon steel, stainless steel, and alloy steel. Each material has its own unique properties and is selected based on the specific needs of the customer.
Step 2: Cutting
Once the materials are selected, they are cut to the desired size using a cutting machine. We use state-of-the-art cutting machines to ensure precision and accuracy in every cut.
Step 3: Heating
After the materials are cut, they are heated to the desired temperature. This helps to reduce any stresses in the material and makes it easier to shape the flange.
Step 4: Forming
The next step in our manufacturing process is forming the flange. We use a hydraulic press to shape the heated material into the desired shape. This ensures that each flange is formed with precision and accuracy.
Step 5: Solid solution
Make the structure and composition of the blank flange uniform, which is particularly important for raw materials. At high temperatures, atomic activity intensifies, σ Phase dissolution, the chemical composition tends to be uniform, and a uniform single-phase structure is obtained after rapid cooling.
Eliminate work hardening to facilitate continuous cold work. The distorted lattice is recovered through solution treatment, the elongated and broken grains are recrystallized, the internal stress is eliminated, the tensile strength of stainless-steel forgings decreases, and the elongation increases.
Restore the inherent corrosion resistance of the flange blank. Due to carbide precipitation and lattice defects caused by cold working, the corrosion resistance of the flange blank is reduced. The corrosion resistance of forgings recovered to the best state after solution treatment.
Step 6: Machining
Once the flange is formed, it undergoes machining to ensure that it is smooth and free from any imperfections. We use CNC machines to achieve the highest level of accuracy in our machining process.
Step 7: Inspection
Before the flange is considered complete, it undergoes a thorough inspection process to ensure that it meets industry standards. Our team of experts inspects each flange to ensure that it is free from any defects and meets the specifications of the customer.
Step 8: Coating
Once the inspection process is complete, the flange is coated to protect it from corrosion and other environmental factors. We offer a variety of coating options, including epoxy, zinc, and galvanized coatings.
Step 9: Packaging and Delivery
Finally, the flange is packaged and prepared for delivery to the customer. We take great care in packaging our products to ensure that they arrive at their destination in pristine condition.
At Jihua, we take great pride in our manufacturing process of reducing flanges. We are committed to producing high-quality flanges that meet the needs of our customers. Contact us today to learn more about our products and services.

Marking of Reducing flanges

The marking of reducing flanges is essential to their manufacture and use. The marking aims to provide information about the flange’s material, size, pressure rating, and other relevant details.
Reducing flanges are typically marked by industry standards, such as ASME B16.5 or EN 1092-1. These standards specify the required information that must be included on the flange, as well as the format and location of the markings.
The required information typically includes the following:

• Flange size
• Pressure rating
• Material specification
• Tag number
• Manufacturer’s name or trademark
• Heat number or lot number
• Date of manufacture

The standard also specifies the location of the marking on the flange. Typically, the marking is placed on the raised face of the flange near the bolt holes. In some cases, the marking may be located on the flange hub or the reducing reducing itself.

Packing of Reducing flanges

How to package reducing flanges? To pack the reducing flange, follow these steps:
When it comes to packaging reducing flanges, it’s important to ensure that they are properly protected and secured during transportation to prevent any damage. We will walk you through some of the key steps to follow when packaging reducing flanges.
Step 1: Clean and Inspect the Flanges
Before packaging the reducing flanges, it’s essential to clean them thoroughly to remove any dust, dirt, or debris that may have accumulated on them. You can use a cloth or brush to clean the flanges and inspect them to ensure they are free from any defects or damages.
Step 2: Choose the Right Packaging Material
The packaging material you choose should be sturdy and able to provide adequate protection to the flanges during transportation. Ideally, you should use a strong cardboard box or wooden crate that can withstand the weight and size of the reducing flanges.
Step 3: Secure the Flanges
Once you have the packaging material ready, you need to secure the flanges to prevent them from moving around or getting damaged during transit. You can use bubble wrap, foam, or any other suitable cushioning material to protect the reducing flanges from impact or shock.
Step 4: Label the Package
Labeling the package correctly is crucial to ensure that it reaches the intended destination without any confusion. You should clearly label the package with the recipient’s address, contact information, and any other necessary details.
Step 5: Arrange for Shipping
After the package is fully prepared and labeled, it’s time to arrange for shipping. You can use a reliable courier or shipping company to ensure that the package is delivered on time and in good condition.
Packaging reducing flanges requires careful planning and attention to detail. By following the above steps, you can ensure that your flanges are properly protected and arrive at their destination safely. Remember to use high-quality packaging materials, secure the reducing flanges properly, and label the package accurately to avoid any mishaps during transportation.

Inspection and measurement of Reducing flanges

There are several factors that need to be considered when inspecting and measuring reducing flanges, including:

Material
The first thing to inspect in a reducing flange is the material. The standard specifies that the flanges should be made from materials such as carbon steel, stainless steel, or alloy steel. The material should be free from any defects such as cracks, porosity, or inclusions that can affect the integrity of the flange.
Dimension
The next thing to inspect in a reducing flange is its dimension. The standard specifies the dimensions of the flanges based on their nominal size and pressure rating. The flanges should be inspected for their inside and outside diameter, thickness, and overall dimensions to ensure they meet the requirements of the standard.
Surface Finish
The surface finish of a flange is also important. The standard specifies that the flanges should have a smooth and even surface finish to ensure proper sealing of the gasket. Any roughness or irregularities on the surface of the flange can lead to leaks in the piping system.
Bolt Hole Alignment
The bolt holes in a flange should be aligned properly to ensure the bolts can be inserted and tightened correctly. The bolt holes should be inspected to ensure they are in the correct position and are not misaligned.
Bolt Hole Size
The size of the bolt holes is also important. The standard specifies the size of the bolt holes based on the nominal size and pressure rating of the flange. The bolt holes should be inspected to ensure they are the correct size and are not damaged.
Bolt Hole Thread
The threads in the bolt holes are important to ensure the bolts can be screwed in and tightened properly. The threads should be inspected to ensure they are clean and free from any damage or defects.

To inspect and measure reducing flanges, you will need a set of calipers or a micrometer to accurately measure the dimensions of the flange. It is also a good idea to have a torque wrench on hand to ensure that the bolts are tightened to the correct torque specification.

Why use a reducing flange?

Figure 2: Two Standard Welding Neck Flanges with a Reducing Flange to achieve the reduction in the pipeline.
An additional reducer is used to reduce the pipework using two standard Welding Neck flanges, as shown in Figure 2. The total length of this configuration is 2L+H, which is much longer than the L+M of a reducing flange joint, as shown in Figure-1. This means that reducing flanges can effectively save space in tight situations. The reducing flange is most commonly used in installations with limited space.

How to purchase the correct reducing flanges?

Are you in the market for reducing flanges but don’t know where to start? Don’t worry, you’re not alone. With so many options available, it can be overwhelming to choose the right flanges for your project. We’ll go over some key factors to consider when purchasing reducing flanges to ensure that you make the right decision.
Determine the Material Needed
The first step to purchasing the correct reducing flanges is to determine the material you need. These flanges are available in a variety of materials, including carbon steel, stainless steel, and alloy steel. The choice of material will depend on the specific application and environmental conditions. If you’re unsure which material to choose, consult with a qualified engineer or supplier to help guide you in making the right decision.
Identify the Flange Face Type
Flange face types refer to the surface finish of a flange, and there are many different types of flange face finishes, including flat face (FF), raised face (RF), ring-type joint (RTJ), tongue and groove (T&G), male and female face (M&F). Each type of flange face has its unique characteristics and is suitable for different applications.

• Flat face (FF): This type of flange face has a flat, smooth surface that is perpendicular to the axis of the pipe. It is typically used for low-pressure applications and when the sealing is achieved by a gasket.
• Raised face (RF): This type of flange face has a raised ring on the surface that surrounds the bolt holes. The ring provides a surface for the gasket to rest on, which helps to create a better seal. It is commonly used in applications with moderate pressure.
• Ring joint face (RTJ): This type of flange face has a specially designed groove to accommodate a metallic ring gasket. The groove is cut into the surface of the flange, and the gasket sits in the groove to create a tight seal. This type of flange face is typically used in high-pressure applications.
• Tongue and groove face (T&G): This type of flange face has a raised tongue on one flange and a matching groove on the other flange. The tongue fits into the groove, creating a tight seal without the need for a gasket. This type of flange face is often used in applications where high pressure and temperature are involved.
• Male and Female Face (M&F): This type of flange face is similar to the tongue and groove face. However, it has a male and female end which creates a face to face contact between two flanges. This type of flange is mainly used for low pressure and low temperature applications.

To identify a specific flange face type, you need to provide me with more information, such as the flange’s application, dimensions, and material.
Determine the Reducing flange Size and Pressure Class
Once you have identified the material and reducing flange type, the next step is to determine the size and pressure class of the reducing flange. reducing flanges are available in various sizes and pressure ratings, and it’s crucial to select the correct size and pressure class to ensure that the flange can withstand the intended operating conditions. You should consult the system specifications and design to determine the appropriate size and pressure class.
Look for Quality and Certifications
It’s essential to ensure that the reducing flanges you purchase are of high quality and come with the necessary certifications. Look for suppliers that have a reputation for delivering high-quality products, and check for relevant certifications, such as ISO 9001, API, and CE, to ensure that the flanges meet industry standards.
Consider the Price
While the price should not be the only factor to consider when purchasing reducing flanges, it’s important to compare prices from different suppliers to ensure that you’re getting a fair price. However, remember that the cheapest option may not always be the best quality, so ensure that you’re not compromising on quality in pursuit of lower costs.
Purchasing the correct reducing flanges can be challenging, but by considering the factors outlined in this post, you can ensure that you make an informed decision that meets your project requirements. Remember to consult with experts and compare suppliers to ensure that you’re getting a high-quality product at a fair price.
