Prashaant Steel & Alloys is Manufacturer, Stockists & Supplier of premium quality range of ASME B16.5 Reducing Flanges, Stainless Steel Nipo Flanges & Other Nipo Flanges that are manufactured under the expert guidance of our diligent workforce.

Similar to Weldo flange,  Nipo  Flange Asme B16.5 Class 300 is a combination of a welding Neck flange and a forged Nipolet. The 2 components of the Nipo Flange Din En 1092-1 are manufactured together as one piece. Stainless steel Nipoflange is made from a single metal piece and is not a welded item. These are manufactured as single body pieces. ANSI B16.5 Class 150 Nipoflange is used for applications like mechanical and chemical industries and also in various other sectors. These flanges are available in a variety of grades, sizes, and standards.

Stainless steel Nipo flange has key features like corrosion resistance capacity, ductility, surface finish and many others. Generally, we manufacture these Stainless Steel Nipo Flange Class 600 which is used for branch pipelines that are to be constructed at 90 degrees. It can be designed according to the requirements of the client. Nipo  flange ansi b16. 5 are also produced in the reinforced variant.
