Ring Type Joint Flanges & RTJF Flange Manufacturers, Suppliers & Exporter in Mumbai, India


Fitwel Industries LLP is ISO certified organization, which has as extensive & wide range of stock of Ring Type Joint Flange. It can be assembled and disassembled easily with Pipes. The Ring Type Joint Flanges are typically used in high-pressure class 600 and high-temperature services above 800°F. RTJ Flange has grooves cut into their faces which steel ring gaskets. The RTJ flange seal when tightened bolts compress the gasket between the flanges into the grooves, deforming the gasket to make intimate contact inside the grooves, creating a metal to metal seal. An ANSI B16.5 RTJ flange may have a raised face with a ring groove machined into it. This raised face does not serve as any part of the sealing means.

We are one of the pioneer manufacturer, supplier & exporter of high-quality Ring Type Joint Flange ANSI B16.5 Ring Type Joint Fanges, RTJ Flanges, Stainless Steel Ring Type Joint Flanges, Carbon Steel RTJ Flanges, Ring Type Joint, Ring Joint Flanges, Class 150 LBS Ring Type Joint Flanges, BS-4504 RTJ Flanges in Mumbai, Pune, India. We supply our manufactured final products to various Industrial uses in petrochemical, oil, gas and allied industries.

RTJ flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other. In this case, the compressed gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension. As the two Ring Type Joint flange 150 lbs are bolted together and further tightened, the applied bolting force on the flange tends to deform the gaskets inside the flange groove. This is known to create a very tight metal to metal seal. To make this happen, the material of the ring joint gasket has to be softer and more ductile as compared to the material of the Ring Type Joint Flange Raised Face. We also offer these products at custom-made sizes and shapes to our respected clienteles. We Export Ring Type Joint Flanges in Qatar, Kingdom Of Bahrain, Saudi Arabia, Indonesia, United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, Australia, etc.

What is Ring type joint flange?

A ring joint type (RTJ) Flanges 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).
A Ring type joint flange (RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened. This compression results in a leak-proof, close-fitting seal on the pipe or connection.

What is the difference between RF and FF flange?

RF is raised face flange, which can be used under the pressure of PN1. 6~PN10MPA. FF is flat face flange, which has lower sealability than RF, its pressure is 1.6~2.0MPA (standard: GB9113), and other joint faces like RTJ, FM have higher pressure. The gaskets for RF and FF can be used for each other.

Ring-Type Joint (RTJ)

The Ring Type Joint flanges are typically used in high pressure (Class 600 and higher rating) and/or high temperature services above 800°F (427°C). They have grooves cut into their faces which steel ring gaskets. The flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or Coining) the gasket to make intimate contact inside the grooves, creating a metal to metal seal.

An RTJ flange may have a raised face with a ring groove machined into it. This raised face does not serve as any part of the sealing means. For RTJ flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other. In this case the compressed gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension.

Ring Type Joint gaskets

Ring Type Joint gaskets are metallic sealing rings, suitable for high-pressure and high-temperature applications. They are always applied to special, accompanying flanges which ensure good, reliable sealing with the correct choice of profiles and material.

Ring Type Joint gaskets are designed to seal by "initial line contact" or wedging action between the mating flange and the gasket. By applying pressure on the seal interface through bolt force, the "softer" metal of the gasket flows into the microfine structure of the harder flange material, and creating a very tight and efficient seal.


Slip On Flanges

Most applied type is style R ring that is manufactured in accordance with ASME B16.20 used with ASME B16.5 flanges, class 150 to 2500. Style 'R' ring type joints are manufactured in both oval and octagonal configurations.

The Octagonal ring has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section.

Style R ring type joints are designed to seal pressure up to 6,250 psi in accordance with ASME B16.5 pressure ratings and up to 5,000 psi.

The RX type is suitable for pressures up to 700 bar. This RTJ is capable of sealing itself. The outer sealing surfaces make the first contact with the flanges. A higher system pressure causes a higher surface pressure. Type RX is interchangeable with the standard R-models.

The BX type is suitable for very high pressures up to 1500 bar. This ring joint is not interchangeable with other types, and is only suited for API type BX flanges and grooves.

The sealing surfaces on the ring joint grooves must be smoothly finished to 63 Microinches and be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a wedging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges.


Choice of Material

The table below indicates the most commonly used materials for ring type joints.

  • Soft iron
  • Carbon steel
  • SS (Stainless steel)
  • Nickel alloys
  • Duplex steel
  • Aluminum
  • Titanium
  • Copper
  • Monel
  • Hastelloy
  • Inconel
  • Incoloy

General flange faces such as the RTJ, TandG and the FandM shall never be bolted together. The reason for this is that the contact surfaces do not match and there is no gasket that has one type on one side and another type on the other side.


Slip On Flanges

Male-and-Female (M&F)

With this type the flanges also must be matched. One flange face has an area that extends beyond the normal flange face (Male). The other flange or mating flange has a matching depression (Female) machined into it's face.

The female face is 3/16-inch deep, the male face is1/4-inch high, and both are smooth finished. The outer diameter of the female face acts to locate and retain the gasket. In principle 2 versions are available; the Small M&F Flanges and the Large M&F Flanges. Custom male and female facings are commonly found on the Heat Exchanger shell to channel and cover flanges.

Advantages and Disadvantages of T&G and M&F flange faces

Advantages

Better sealing properties, more precise location and exact compression af sealing material, utilization of other, more suitable sealing and spezialized sealing material (O-rings).


Disadvantages

Commercial availabillity and cost. Normal raised faced is far more common and ready available both regarding Valves, flanges and sealing material. Another complexity is that some rigid rules must be applied to the piping design. Do you order Valves to be female end both sides, or on one side maybe, in which case do you point all male ends in the flow direction, or what. Same applies to any flanged joint / vessel connection of course.


Join or match an RTJ flange with a RF flange

  • Several times I have been asked: may I join or match an RTJ flange with a RF flange?. My answer of course: that is not allowed. Today April 29, 2012, the question was asked again. I will try to explain why a connection between an RF and RTJ flange is not acceptable.
  • RTJ flanges have grooves in their sealing faces, while RF flanges do not. If you want to make a connection between the two flanges, you can only apply a flat gasket. This flat gasket wil be make full contact with de sealing surface of the RF flange, but not with the sealing surface of the RTJ flange. Due to the groove in the flange RTJ a certain portion of the gasket is not utilized, and therefore it is not possible to make a properly sealed flange connection. Further, the RTJ flange will be damage the gasket, especially if a spiral wound or metal jacketed gasket is applied.
    My advice is: never make an RF-RTJ flange connection. Maybe do you have not direct a spill, but when an accident happens, the insurance experts know where they can find you.
    Consider injuries or fatalities, a wrong flange connection is't worth it.
