Remark s of the Author The other flange or mating flange has a matching depression Female machined into it’s face. These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter.

Sometimes a seal weld is also used together with the threaded connection. Fundici 29 August, For Lxp flanges that seal with ring gaskets, the raised faces of the connected and tightened flanges may contact each other.

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. 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. 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 joont to metal seal.

Commercial availabillity and cost. You have seen all photos. RTJ flanges have grooves in their sealing faces, while RF flanges do not. RF Slip on Flange: Today April 29,the question was asked again. Style “R” ring type joints are manufactured in both oval and octagonal configurations. 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.


Do you order Valves to be female end both sides, or on one side maybe, in which case do bridsa point all male ends in the flow direction, or what.

Definition and Details of Flanges – Flange Faces

Another complexity is that some rigid rules must be applied to the piping design. The hardness of the ring should always be less than the hardness of the flanges.

Send This is not what you are looking for? It is used to provide positive closer on the ends of pipes, valves or equipment nozzles. 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.

However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. 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.

An RTJ flange may have a raised face with a ring groove machined into it. The reason for this is joinr 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.

Weld neck pipe flanges are often used for high pressure applications. Custom male and female facings are commonly found on the Heat Exchanger shell to channel and cover flanges. Ring Type Joint gaskets are metallic sealing rings, suitable for high-pressure and high-temperature applications. A blind bridxs is used to close ends of piping systems. The fabrication of this type of flange is similar to that of a slip-on flange.

ANSI B Class Lap Joint Flanges On Coastal Flange

If you want to make a connection between the two flanges, you can only apply a flat gasket. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe. What is the warranty for the product?


Definition and Details of Flanges – Flange Faces Flange faces Different types of flange faces are used as the contact surfaces to seat the sealing gasket material. This raised face does not serve as any part of the sealing means. Better sealing properties, more precise location and exact compression af sealing material, utilization of other, more suitable sealing and spezialized sealing material O-rings.

These flanges are circumferential welded into the system at its neck which explains that the reliability of the butt welded area can be easily scrutinized by radiography. It is the last photo. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.

Enter between 20 to 4, characters. Request a custom order and have something just for you! The newer flat bottom groove design will accept either the oval or the octagonal cross section. Tongue-and-groove facings are standardized in both large and small types. The bores of both flange and pipe match, which decreases erosion and turbulence in the pipeline. It is referred to joinf a raised face because the gasket surfaces are raised above the bolting circle face.

With this type the flanges also must be matched. These are commonly found on pump covers and Valve Bonnets. Home About US Quality. They are always applied to special, accompanying flanges which ensure good, reliable sealing with the correct choice of profiles and material.
