Forged flanges

Forged Flanges

Flanges are used in piping to control the flow and to connect the piping components together. The flanges can be made through different methods. The Forged Flanges are made by forging the metal into the desired shape and dimensions. They can range from ½ inches to 48 inches in size, and have pressure classes ranging from 150 LBS to 2500 LBS, and so on. There are different connection types to the flanges as well.

Forged pipe flange are fitted with bolts and nuts. They are not welded in most cases. This allows for the piping components to be replaced when necessary. Even though they are fitted with bolts and nuts, they provide the necessary strength as they are forged. To make sure that the connection is leak-proof, the forged welding neck flange are fitted with gaskets in between.

Forged Steel Flanges are made from a single piece of metal. The metal is either presented in the form of billets, slabs, or any other form. It is then heated to a specific temperature where the metal has enough plasticity to be forged. The metal is pressed through a press, power hammer, or die until it gets to the desired shape and size. The Forged Flanges Manufacturer produces flanges in different dimensions and shapes. The forging provides a continuous grain flow that improves the strength of the flange and makes the material an even distribution.

Steel forged flange come with a number of connection types. There are ring-type joints, lap joint face, raised face, flat face, large male-female, small male-female, large tongue and groove, and small tongue and groove are some of the connection types.
Forged aluminum flanges also have different faces. The most common ones are the flat face, raised face, and ring joint.

Direct buy from the leading manufacturers of forged welding neck flange at economical rates in the Sharjah.

Forged carbon steel flanges have a standard specification as ASME B16.5. It can also be equivalently marked as ANSI B16.5, ANSI B16.47, ANSI B16.36, ANSI B16.48, BS 4504, EN1092, UNI 2277/2278, DIN, JIS, SABS1123, or GOST-12820. Forged welded flange have their specifications according to these standards. The flange dimensions can be checked against these specifications to see if the flanges are up to the standards.

Stainless steel forged pipe flange have to perform to the expected level. So the performance of the flanges can be tested. The tensile test is the most important. The flanges can be stretched on the tensile testing machine to get the result. The elastic deformation during the yield point is also tested. The bending test and the impact test provide different parameters too.
