Industrial Pipe Flange

Stainless Steel Threaded Reducing Flange Manufacturer

Manufacturer of 2 X 1 To 8 X 4 Reducing Weld Neck Flange in India, We Are Largest Independent Supplier Of Reducing Slip On Flange ANSI B16.5 in Mumbai.


Flanges are circular rims with projections outwards with a collar or rib sometimes to cause strength at the attachment site. There are different types of Flange and different material grades are used to produce these flanges. Rajveer Stainless And Alloys is a manufacturer and supplier of different flanges. The Carbon Steel Reducing Flange is made up of carbon steel to add to the strength and to make the pipe diameter smaller at connection. Reduction fittings are useful when reducing the volume of fluid flow. There are different dimensions of these flanges. The ASME B16.5 Reducing Flange is a type of flange falling under the specification that covers the outer diameter ranging from ½ inches to 24 inches and including the pressure class 150 to Class 2500.

What Is ASME B16.5 Reducing Flange

The Reducing Companion Flange carries two functions at once. It reduces the volume of fluid flow and also acts as a coupling between two pipes with threads. The Stainless Steel Reducing Flange Dimensions change according to the standards and pipe sizes they are used in. EN 1092 Aluminum Reducing Flange has a socket attached to it to hold the pipes so that welding is easier and the connection becomes better. A variation is the Reducing Weld Neck Flange which has a neck like structure welded in and it also makes welding easier. We manufacture different types and sizes of flanges.

What Is The Difference Between Threaded Reducing Flange And Weld Neck Reducing Flange?

The flanges are pipe fittings that are used to connect pieces of pipes together. There are different types of flanges for different purposes. The threaded flanges have threads whereas the weld neck flanges have necks welded onto them. The threads make the flanges easy to install with the threads and they could either be welded or not depending on the need. The weld neck flanges are welded to make the connections. Both the threaded and weld neck reducing flanges are used to reduce the volume of the flow at the connections. The only difference is in the fitting mechanism that there threaded reducing flange can be connected with the threads on the pipes where the weld neck reducing flanges have to be welded onto the pipes.
