Consider injuries or fatalities, a wrong flange connection is’t worth it.
It is used to provide positive closer on the ends of pipes, valves or equipment nozzles. Pap 29 August, They have grooves cut into their faces which steel ring gaskets. 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.
Stainless Steel Slip on Flanges, Dn10-500mm Od Lap Joint Flanges
Typical questions asked about products Does this product support customization? Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. In pressure classes andthe height of raised face is approximately 1. Normal raised faced is far more common and ready available both regarding Valves, flanges and sealing material.
With this type the flanges also must be matched. Raised Face RF The Raised Face flange is the most common type used in process plant applications, and is easily to identify. These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter.
Tongue-and-groove facings are standardized in both large and small types. Fund joiny August, For RTJ flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other. One flange face has an area that extends beyond the normal flange face Male. Due to the groove in the flange RTJ a brodas portion of the gasket is not utilized, and therefore it is not possible to make a properly sealed flange connection.
In this case the compressed gasket will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the lwp and lessen the connecting tension. Style “R” ring type joints are manufactured in both oval and octagonal configurations. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.
Stainless Steel Flanges – Aceros y Tuberias
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. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. The newer flat bottom groove design will accept either the oval or the octagonal cross section. 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.
Definition and Details of Flanges – Flange Faces
The bores of both flange and pipe match, which decreases erosion and turbulence in the pipeline. The outer diameter of the female face acts to locate and retain the gasket.
You have seen all photos. Further, the RTJ flange will be damage the gasket, especially if a spiral wound or metal jacketed gasket is applied.
The hardness of the ring should always be less than the hardness of the lal.
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. Different types of flange faces are lp as the contact surfaces to seat the sealing gasket material.
By applying pressure on the seal interface bdidas 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. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation. Pressure rating of the flange determines the height of jooint raised face.
These flanges are ideal for lower pressure applications. Send This is not what you are looking for? They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded joont are threaded in the bore which match an external thread on the pipe. 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.
ANSI B Class Lap Joint Flanges On Coastal Flange
Material 29 August, RTJ flanges have grooves in their sealing faces, while RF flanges do not. These are type of flanges that slide over the end of piping and then welded in place. My answer of course: These flanges are circumferential welded into the system at its neck which ioint that the reliability of the butt welded area can be joont scrutinized by radiography. 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.
However, only the oval cross section can la used in the old type round bottom groove. The flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming or Bridsa the gasket to make intimate contact inside the grooves, creating a metal to metal seal. What is the warranty for the product?

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. Flat face flanges are never to be bolted to a raised face flange.
