Characteristics Of Stainless Steel RTJ Flange

Stainless Steel RTJ Flanges are employed in cryogenic and high-wear and tear situations. The material is extremely resistant to oxidation and abrasion. Because of its high mechanical qualities, ASME B16.5 RTJ Flange is employed in boilers and large exhaust systems. The flanges are available in ASTM A182 and A240 sizes. By design, these are forged, cast, or high temperature applications, as well as high pressure service implementations. These flanges are also ANSI, ASME, BS, and EN compliant.

Machining ASME B16.5 RTJ Flange Grooves

The Ring Type Joint Flange is often regarded as the most economical flange in industrial piping systems. Internal pressures are used by the ring and groove structure to improve the sealing ability of the interconnecting flanges. The greater the piping system's working force, the better the sealing efficiency. They are particularly useful for difficult services including high pressures, extreme heat, cyclic loads and temperatures, among other things.

Check Difference Between RTJ Flange Vs RF Flange, Advantages & Disadvantages Of ASTM A182 F304 Ring Type Joint Flanges

How Does A Carbon Steel Ring Type Joint Flange Work?

They have slots in their faces that are filled with steel ring gaskets. When the bolts are pressed, the gasket between the flanges is compressed into the grooves. It thenwarps the gasket to make close connection inside the grooves, resulting in a metal to metal barrier.
A raised surface with a ring groove can be cut into a Carbon Steel RTJ Flange. This elevated face is not an element of the sealing mechanism. The elevated faces of the linked and compressed RTJ flanges may come into touch with each other.

What Type Of Gasket Goes With An Ring Type Joint Flange

A Carbon Steel Ring Type Joint Flange can withstand high pressure and high temperatures. The RTJ Gaskets come in R, RX, and BX forms, as well as octagonal profiles. R solid pieces (oval and octagonal) to suit conventional ring joint flanges having trapezoidal grooves.

For wellhead values above 700 bar, models RX and BX with complicated bevelled edge sections are available.

Ring Type Joint Advantages
Ring Type Joint Advantages
  • SS RTJ Flanges is one of the efficient flanges used for high-temperature pressure piping systems.
  • Ring and groove layout use inner pressures to increase the sealing capacity of the connecting flanges.
  • ASTM A105 RTJ flanges also are appropriate for cyclic stresses and corrosive fluids.
RTJ Flange Disadvantages
RTJ Flange Disadvantages
  • main disadvantage of a ring-type joint flanges is the price because of its complicated configuration and particular machining control for each the metal ring gasket and the ring-joint groove.
  • This may additionally name for sufficient space which limits the application of CS RTJ flanges in crowded installations.

Difference Between

  • RTJ : A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular).
  • Raised Face flange (RF) is easy to recognize as the gasket surface area is positioned above the bolting line of the flange.

Connection Of RTJ Type Flange


A RTJ flanges is a machined steel ring with a deep groove reduce into its face. This groove rests a steel ring which receives compressed when the connecting bolt of the flanges are tightened. This compression outcomes in a leak-proof, close-fittings seal on the pipe or connection.
