Small Tongue And Groove Flanges Manufacturer, Suppliers & Exporter Mumbai, India


Fitwel Industries LLP is a leading independent manufacture, supplier and exporter in Mumbai India. We have extensive experience in supplying small tongue and groove flanges in all standard in which the common world standards include ASAI/ ANSI/ ASME, BS10, PN/ DIN and JIS/ KS Flanges are stocked or available in the following range of sizes and materials for the petrochemical, oil, gas and allied industries. Tongue and Groove Flange can be forged or plate be assembled and disassembled easily with Pipes. In the Tongue & Groove Flange Asme B16.5 Class 300, both the Tongue face as well as the Groove faces of must be matched to each other.

One of the flange faces has been produced with a raised ring also referred to as Tongue, machined onto the flange face by the Tongue & Groove Flange Manufacturer in India. Tongue & Groove Flange Jis 16k facings have been standardized in both large and small types. The Tongue & Groove Flange Din En 1092-1 are different from male and female flanges in terms of the inside diameters. To elaborate, the inside diameters of the Tongue & Groove Flange Awwa C207 Class D do not extend into the flange base, thus the gasket has been retained on its inner and outer diameter. The Tongue & Groove Flange Jis 5k are commonly found on pump covers and Valve Bonnets.

Tongue & Groove Flange Asme B16.5 joints also have an added advantage i.e. they are self-aligning and have a tendancy to act as a reservoir for the adhesive. The scarf joint in the Tongue & Groove Flange Jis 10k keeps the axis of loading in line or aligned with the joint. Hence, the Tongue & Groove Flange Class 600 does not require any major machining operation.

Built to align with the Tongue and Groove ears, one side of these Tongue groove flanges has a raised ring, which is referred to as a Tongue that is machined onto the face of the flange whereas the mating flange will have a corresponding depression or known as a Groove machined in its nose. Both large as well as small kinds of tongue and groove facings are standardized, which in turn vary from male and female type of flange in terms of the internal diameter of the tongue and groove ones. The internal diameters of the tongue and groove facing do not reach into the base of the flange, thus the gasket is held on its inner and outer diameter. Commonly a Carbon steel grooved flange is found on Valve Bonnets or on pump coverings. A benefit of having ANSI B16.5 Tongue and groove flange connections is that they tend to be self-aligned, thus, serving as an elastic buffer. The scarf joint of this kind of Stainless steel grooved flange is what holds the loading point in line with the joint, which is why it does not require an intensive machining process. Specific flange faces such as the RTJ, Tongue and Groove, and Female and Male are not to be bolted. This is because the touch surfaces do not overlap along with the absence of a gasket which has one type on one hand and another type on the other. Typically these flanges are recommended to be used in a low pressured, yet non-critical applications, in order to attach other Groove and Tongue components such as the Groove flange adapter. Groove and Tongue flanges are used to connect other Groove and Tongue components in low pressure, non-critical applications.

What is a Flange face?

Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. ASME B16.5 and B16.47 define various types of flange facings, including the raised face, the large male and female facings which have identical dimensions to provide a relatively large contact area.

Other flange facings covered by these standards include the large and small tongue-and-groove facings, and the ring joint facing specifically for ring joint type metal gaskets.


Raised Face (RF)

The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types.

The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint. Diameter and height are in ASME B16.5 defined, by pressure class and diameter. Pressure rating of the flange determines the height of the raised face.

The typical flange face finish for ASME B16.5 RF flanges is 125 to 250 µin Ra (3 to 6 µm Ra).

Raised Face flange

Raised Face height

For the height measures H and B of all described dimensions of flanges on this website, with exception of the Lap Joint flange, it is important to understand and remember the following:

In pressure classes 150 and 300, the height of raised face is approximately 1.6 mm (1/16 inch). In these two pressure classes, almost all suppliers of flanges, show in their catalog or brochure, the H and B dimensions including the raised face height. ((Fig. 1))

Slip On Flanges

In pressure classes 400, 600, 900, 1500 and 2500, the height of raised face is approximately 6.4 mm (1/4 inch). In these pressure classes, most suppliers show the H and B dimensions excluding the raised face height. (Fig. 2)


Flat Face (FF)

The Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.

Flat face flanges are never to be bolted to a raised face flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

Slip On Flanges

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.


Slip On Flanges

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

Tongue and Groove (T&G)

The Tongue and Groove faces of this flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into it's face.

Tongue-and-groove facings are standardized in both large and small types. They differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. These are commonly found on pump covers and Valve Bonnets.

Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.

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.
