ASME B16.5 Ring Type Joint Flanges

A ring type joint flange seals against pressure with a metal ring compressed into matching grooves on two flange faces, instead of relying on a flat gasket alone. NeoImpex machines rtj flanges to ASME B16.5 across pressure classes 150 through 2500, with octagonal and oval groove profiles for oil and gas, petrochemical, and high-pressure piping lines. Buyers specify a ring joint flange wherever bolt load alone can't guarantee a leak-tight seal at elevated pressure and temperature. Standard gasket flanges start to weep long before an RTJ joint does.

What Are Ring Type Joint Flanges (RTJ)?

An RTJ flange carries a machined groove on its face instead of a flat sealing surface. A solid metal ring, usually oval or octagonal in cross-section sits in that groove and deforms slightly under bolt load, biting into both flange faces to form the seal. Because the ring carries the sealing load, not the bolts, the joint stays tight through thermal cycling that would loosen a soft-gasket connection.

Benefits of Ring Joint Flanges

  • - Holds a seal through repeated pressure and temperature swings without gasket extrusion
  • - Metal-to-metal ring contact reduces gouging on the flange face compared to compressed gaskets
  • - Performs consistently at class 900 and above, where flat gaskets start to fail
  • - Rings are replaceable on their own no need to re-machine or re-face the flange

What Is an RTJ Flange Used For?

RTJ flanges connect wellhead and Christmas tree assemblies on upstream oil and gas sites, high-pressure steam headers, subsea piping runs, and refinery units handling sour, H₂S-bearing service. Anywhere a single gasket failure means a shutdown, RTJ construction is the default spec.

What are B16.5 Ring Type Joint Flanges?

B16.5 Ring Type Joint (RTJ) Flanges are used in high pressure and high temperature applications. They have a specially designed groove on their face that accommodates a metal ring gasket, which provides a secure & leak-free seal.

What are the benefits of the ASME B16.5 RTJ Flanges?

The benefits of ASME B16.5 RTJ Flanges include their ability to provide a reliable and leak-free seal, even under extreme pressure and temperature conditions. The metal ring gasket ensures a tight seal, reducing the risk of leakage & preventing damage to equipment & the environment. Additionally, RTJ flanges are highly durable & can withstand harsh operating conditions.

What is RTJ Flanges used for?

RTJ Flanges are used in various industries, including oil and gas, chemical processing, and power generation. They are commonly used in pipelines, valves, and other high-pressure equipment that requires a secure & leak-free seal. RTJ flanges are ideal for applications where the operating conditions are extreme & traditional flanges may not provide a reliable seal.
