Probably the best welding flange available because of its high, heavy neck.

The blind flange is a blank disc with a bolt hole. These types of flanges are used with another type of flange to isolate the piping system or to terminate the piping as an end. Blind flanges are also used as a manhole cover in the vessel. Based on Flange facing Types , it can be further classified as. 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.

You can also choose from iron, plastic. As well as from casting. There are flange types pdf suppliers, mainly located in Asia.

The top supplying country or region is China, which supply 1 of flange types pdf respectively. Flange types pdf products are most popular in United States, Singapore, and Germany. STANDARD TYPES OF FLANGES.

The type of flange to be used for a piping application depends, mainly, on the required strength for the flanged joint. Let’s now dive in, showing the key types of flanges with pictures. Below are the types of flanges used in piping based on facing. Flat Face (FF) Flanges : These pipe flanges are used when the counter flanges are flat face.

Sometimes referred to as Counter Bore flanges , the Socket Weld types have a socket to insert pipe when space limitations make Weld Neck flanges difficult to use. RTJ flanges are considered to be the most efficient flanges for use in pipeline design. Rather than using a gasket between the connecting flanges, RTJ flanges have a deep groove in a ring shared around the face. Ring type gaskets must be used on this type of flange. This type of flange has hardly changed.

Thus, a comparison is done only for this sealing surfaces. Due to the change of the designation of the sealing surface mistakes may occur occasionally. Waveguide Flanges, General Information.

Flann is able to provide ‘free fit’ waveguide flanges for WG(WR650) to WG(WR3) for customers’ own manufacturing assemblies.

This is modified form of the protected type flange coupling. The rubber or leather bushes are used over the pins. The coupling has two halves dissimilar in construction. The pins are rigidly fastened by nuts to one of the flange and kept loose on the other flange. To ensure your always familiar with these, here are of the most common flange types and a description of what they are best used for: Weld-neck.

Complete with a tapered hub, these flanges are recognisable and used in high pressure environments. The flange is particularly useful under repeat bending conditions. Coastal Flange stocks import and domestic ANSI B16. As already described before, the most used flange types ASME B16.

Below you will find a short description and definition of each type, completed with an detailed image. Most common flange types. In this type of flange , the stub is butt welded to the pipe, whereas flange is freely moved over the stub end.
