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.

Ring Joint Flange

Ring Joint Flanges (RTJ) is used when a metal-to-metal seal between the mating flanges is required (which is a condition for high-pressure and high-temperature applications, i.e. above 700/800 C°). A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular).

We manufacture Galvanized RTJ FLANGE, Stainless steel (SS) RTJ FLANGE, Carbon steel (CS) RTJ FLANGE, MS RTJ FLANGE, Alloy RTJ FLANGE, Nicked RTJ FLANGE, Duplex stainless steel (DSS) RTJ FLANGE, Super Duplex stainless Steel (SDSS) RTJ FLANGE and Brass RTJ FLANGE.

We manufacture RTJ FLANGE as per ASME B16.5, ASME B16.47, DIN, etc.
We are manufacturers and suppliers of RTJ FLANGE since the year 1971.


Frequently Asked Questions

Most frequent questions and answers

What is a ring joint flange?

A ring joint flange (RTJ flange) is a type of flange that is used in high-pressure and high-temperature applications, such as the oil and gas industry. The RTJ flange is designed to provide a tight, leak-proof seal between two pipes or between a pipe and a piece of equipment. The flange consists of two parts: a grooved flange, which is attached to the pipe or equipment, and a ring gasket, which is inserted into the grooves of the flange and then compressed between the flange and its mating surface to create a seal. The ring gasket is typically made of a soft metal such as copper or aluminum, and the flange is typically made of a harder metal such as steel. RTJ flanges are typically used in situations where high pressures and temperatures are expected, such as in the oil and gas industry. They are also used in high-pressure applications such as refineries, petrochemical plants, and power generation plants. The ring-joint gasket design is highly resistant to high pressure, high temperature, and vibration. The ring joint gasket can be made of metal and non-metal materials, such as Oval ring joint gasket, Octagonal ring joint gasket, and RX ring joint gasket.

How does a ring joint gasket function?

A ring joint gasket is a type of mechanical seal that is used in high-pressure and high-temperature applications, such as in pipelines, valves, and flanges. The gasket is typically made of metal and is designed to fit into a groove on the flange, creating a tight seal when the flange is tightened. The gasket’s shape, typically an octagonal or circular cross section, and its material properties such as its hardness and elasticity, allow it to maintain its shape and seal integrity despite high pressure and temperature fluctuations.


What are the different types of ring joint flanges?

The most common types of ring joint flanges are RTJ flanges, also known as raised face ring joint flanges, and RX flanges, also known as full face ring joint flanges. RTJ flanges have a raised face, while RX flanges have a flat face.

What is the difference between RTJ and RX flanges?

The main difference between RTJ and RX flanges is their face design. RTJ flanges have a raised face, while RX flanges have a flat face. RTJ flanges are more common and are used in most high-pressure and high-temperature applications, while RX flanges are typically used in extremely high-pressure applications.

What are the most common materials used for ring joint flanges?

The most common materials used for ring joint flanges are carbon steel, stainless steel, and alloy steel. The choice of material will depend on the specific application and the operating conditions, such as pressure and temperature.

How are ring joint flanges installed?

Ring joint flanges are typically installed by first properly aligning the flanges, then placing the ring joint gasket in the groove on the flange, and finally tightening the bolts to create a tight seal. It is important to use the correct torque and tightening sequence to ensure a proper sea
