NFE 29203 Flange

NFE 29203 Flange Dimensions vary with the required pipe size. Rajveer Stainless And Alloys produces flanges of all types and sizes in this specification. Our flanges range up to 2560mm in outer diameter of the flanges. They range from DN10 to DN600 in size as well. There are different pressure containments according to the different NFE 29203 Standard specifications. They could range from welding neck flanges, blind, lapped joint, socket weld, orifice types to long weld neck and threaded flanges. The application requirement determines the type of flange used. The NFE 29203 Slip on Flange is used in applications that require precise fitting of the flange with adjustable placement.

Water systems, natural gas and oil supply applications use this kind of flanges more. The NFE 29203 Weld Neck Flange is with a welded neck that makes the welding onto a pipe much stronger and easier. Electric power plants and ship building industries use these types of flanges as well. Sometimes the flanges are used to close a certain pipeline. In this case, the NFE 29203 Blind Flange is used. It has a flat closure at the end and therefore terminates a line of pipes. The NFE 29203 Threaded Flange is used with applications where the pipe and the flanges are connected through threads. The pipes usually have male threads and the flanges with female threads. We supply all these types of flanges to our customers. Please contact us for any custom orders.

What is NFE 29203 flange equivalent material?

The NFE 29203 flanges come in the range of PN2.5 to PN420 pressure range with the DN size range of DN10 to DN600. These flanges are used in oil and gas, electric, nuclear power plant, off shore industries, ship building, petroleum and in chemical industries. So any alloyed flange that could have the capacities as these flanges could be used as equivalents to these flanges. The 316 austenitic stainless steel flanges, super duplex grade flanges and other alloyed steel flanges could also be used as equivalents. The only concern is that the equivalent materials should meet the application requirement in terms of mechanical properties and the project requirements in terms of the cost.
