Ring Type Joint Flanges

Understanding your choice of ring type joint flanges options

The right RTJ flange option depends on operating conditions, fluid characteristics, and system design. Here are some of the considerations you should keep in mind when selecting your RTJ flange option:

Operating Temperature and Pressure: Consider the operating temperature and pressure of the system to determine the appropriate material and design of the RTJ flange.

• Fluid Characteristics: Consider the fluid’s transport characteristics, such as its corrosive and abrasive properties, to select the appropriate RTJ flange option to withstand the fluid’s effects.
• System Design: Consider the system’s design, including the flange size and connection type, to ensure the RTJ flange option selected is compatible with the system.

What are ring type joint flanges?

A ring-type joint flange is a machined metal ring with a deep groove on its surface. A metal RTJ gasket is located in the groove and is used to seal the flange pair. When the attachment bolts of the RTJ flange are tightened, the gasket is compressed, and the flange pair forms a leak-proof seal.

Characteristics of RTJ flanges

Ring joint flanges are very different from other flanges used in the pipe and tube industry. the main features of RTJ flanges are following:
Use of steel gaskets rather than flat composite gaskets
Unlike conventional flanges, RTJ flanges use a steel gasket as the sealing element rather than a flat composite gasket. This design provides better sealing performance and longer service life. The steel gasket sits on a machined recess that ensures a tight fit on the sealing surface, thus preventing media leakage.
Sealing by deformation of soft metal gaskets
Sealing of RTJ flanges is achieved by deformation of the soft metal gasket. When the flange is tightened, the soft metal gasket flows into the microstructure of the hard flange material, thus creating a reliable seal. This type of seal is more reliable than conventional flat composite gaskets and can withstand higher pressures and temperatures.
Superior Metal-to-Metal Sealing Performance
RTJ flanges offer superior metal-to-metal sealing performance. Due to the tight fit between the steel gasket and the hard flange material, RTJ flanges can operate in high temperature, high pressure and corrosive media environments without leakage problems.
Raised face provides additional load
Raised surfaces may be present in RTJ flanges, but do not contain pressure. When tightening RTJ flanges, if the raised faces are in contact with each other, additional load is transferred to these faces, providing joint integrity during over-tightening, vibration and movement.
Easy to assemble and disassemble
RTJ flanges are very easy to assemble and disassemble, which makes them ideal for use in maintenance and replacement piping systems. Only simple tools and skills are required to perform assembly and disassembly operations.

Sealing principle of RTJ flange

When a metal-to-metal seal between mating flanges is required (which is the condition for high-pressure and high-temperature applications, i.e., above 700/800C°), ring joint flanges (RTJ) is used.
Ring joint flanges have circular recesses to accommodate ring joint gaskets (oval or rectangular). When two ring joint flanges are bolted and then tightened, the applied bolt force deforms the gasket in the groove, creating a very tight metal-to-metal seal. In order to achieve this, the material of the ring joint gasket must be softer (more ductile) than the material of the flange.
RTJ flanges can be sealed by RTJ gaskets of different types (R, RX, BX) and profiles (e.g., octagonal/elliptical for R type).
The most common RTJ gasket is the R type with an octagonal cross-section, as it ensures a very strong seal (an oval cross-section is the older type). However, the “flat groove” design accepts both types of RTJ gaskets with octagonal or elliptical cross-sections.

Types of Ring Type Joint Flanges

There are four basic types of RTJ flange that you will need to choose from, and these are:

• R Oval RTJ Flange
• R Octagonal RTJ Flange
• RX RTJ Flange
• BX RTJ Flange

In the following sections, we will describe each flange type in more detail.

R Oval RTJ Flange

The R Oval RTJ flange is characterized by its oval shape, which provides a good seal between the flanges. This type of flange is commonly used in low-pressure applications and is suitable for use with both flat-faced and raised-face flanges. The R Oval RTJ flange is manufactured by ASME B16.20 standards and is available in a range of sizes and materials.

R Octagonal RTJ Flange

The R Octagonal RTJ flange is characterized by its octagonal shape, which provides a better seal than the R Oval RTJ flange. This type of flange is commonly used in medium-pressure applications and is suitable for use with both flat-faced and raised-face flanges. The R Octagonal RTJ flange is also manufactured by ASME B16.20 standards and is available in a range of sizes and materials.

RX RTJ Flange

The RX RTJ flange is characterized by its hexagonal shape and is designed for high-pressure applications. The RX flange provides a greater sealing surface than the R Oval or R Octagonal RTJ flange and is suitable for use with raised-face flanges. The RX RTJ flange is also manufactured by ASME B16.20 standards and is available in a range of sizes and materials.

BX RTJ Flange

The BX RTJ flange is characterized by its trapezoidal shape and is designed for ultra-high-pressure applications. The BX flange provides the greatest sealing surface of all the RTJ flange types and is suitable for raised-face flanges. The BX RTJ flange is also manufactured by ASME B16.20 standards and is available in a range of sizes and materials.

Dimensions of Ring type joint flanges

RTJ flange sizes are typically specified in design standards. For example, when the design specification is ASME B16.5, a table of RTJ flange sizes for each pressure class is provided for flanges up to 24 inches. For RTJ flanges over 24 inches in size, the RTJ flange dimensions can be found in ASME B16.47.
Therefore, RTJ flange sizes are fixed for standard flanges and do not vary by manufacturer. However, custom RTJ flanges can be manufactured, and the buyer will need to specify the flange size.

Manufacturing process of Ring type joint flanges

Ring type joint 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 type joint 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.

Inspection and measurement of Ring type joint flanges

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

Material
The first thing to inspect in a ring type joint 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 type joint 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 type joint 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.

The first step to purchasing the correct ring type joint 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 Ring type joint flange Size and Pressure Class
Once you have identified the material and ring type joint flange type, the next step is to determine the size and pressure class of the ring type joint flange. ring type joint 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.
