Understanding your choice of ring spacer or spade flanges options
Choosing the right ring spacer or spade flange is critical to ensuring the proper operation of your piping system. With so many options available, deciding which type of ring spacer or spade flange is best for your needs can be overwhelming. Jihua will guide you through the different types of ring spacers or spades flanges and help you understand your options.
What are ring spacers or spades flanges?
Ring spacer flanges, also known as isolation flanges or spacer rings, are used to separate sections of piping or equipment that need to be insulated or have different types of fluids flowing through them. They consist of a combination of a ring-shaped spacer and a flange that fits between two pipes or equipment. The ring-shaped spacer is used to increase the distance between the two flanges, providing the necessary space to accommodate insulation material or other components.
Spade flanges, also known as line blind flanges, are used to temporarily shut off the flow of fluid in a piping system. They consist of a combination of a spade and a flange that fits between two pipes or equipment. The spade is used to block the flow of fluid when inserted into the flange.
Types of Ring Spacer / Spade Flanges
There are three types of ring spacers or spades flanges:
- Flat face ring spacer or spade flange (FF): similar to a flat face flange, the surface of the disc is flat (suited for flat face gaskets, for low-pressure applications).
- Raised face ring spacer or spade flange (RF): likewise raised face flanges, there is an additional thickness on the surface of the disc. This type fits semi-metallic gaskets, as the spiral wound type.
- Ring joint face ring spacer or spade flange (RTJ): a groove is inscribed on the surface of the disc. This type is used in conjunction with ring joint gaskets.
Standard for Ring Spacer / Spade Flanges
The most commonly used standards are ASME B16.48 (similar to the API 590) which covers Spade and Spacers for pipes up to nominal bore of 600mm depending on the pressure class. This standard refers to B16.5 which provides the dimensions for the mating flanges.

Manufacturing process of Ring Spacer / Spade Flanges
Ring Spacer / Spade 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 ring spacer or spade 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 ring spacer or spade 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 Ring Spacer / Spade Flanges
The marking of ring spacer or spade 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.
Ring Spacer / Spade Flanges are typically marked by industry standards, such as ASME B16.5 or ASME B16.48. 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

Inspection and measurement of Ring Spacer / Spade Flanges
There are several factors that need to be considered when inspecting and measuring ring spacer or spade flanges, including:
Material
The first thing to inspect in a ring spacer or spade 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 ring spacer or spade 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 ring spacer or spade 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.
Application of Ring Spacer / Spade Flanges
Ring Spacer / Spade Flanges are widely used in various industries, including oil and gas, chemical, petrochemical, power generation, water treatment, and HVAC. The following are some common applications for annular gaskets or spade flanges:
- Pipeline maintenance: ring spacer or spade flanges are used to separate sections of piping in a pipeline system during maintenance or repair. By installing a ring spacer or spade flange, the section of piping can be isolated and taken out of service without having to shut down the entire system.
- Pressure management: In high-pressure piping systems, ring spacer or spade flanges are used to reduce the overall pressure of the system. By placing a ring spacer or spade flange between two flanges, the distance between the flanges is increased, which reduces the pressure in the piping system.
- Temperature management: ring spacer or spade flanges can also be used to manage the temperature of a piping system. By placing a ring spacer or spade flange between two flanges, the distance between the flanges is increased, which can help to reduce the temperature of the system by allowing for greater heat dissipation.
- Alignment correction: In some cases, piping systems may become misaligned due to thermal expansion or other factors. ring spacer or spade flanges can be used to correct this misalignment by providing a means to adjust the position of the piping.
How to purchase the correct ring spacer or spade flanges?
Are you in the market for ring spacer or spade 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 ring spacer or spade flanges to ensure that you make the right decision.
Determine the Material Needed
The first step to purchasing the correct ring spacer or spade 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.
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 Ring Spacer / Spade Flange Size and Pressure Class
