ANSI B16.5 / ASME B16.47 Nipoflange Supplier, Manufacturer in India

ANSI B16.5 / ASME B16.47 Nipoflange Supplier, Manufacturer

Unichem Steel & Alloy Pvt. Ltd. is a renowned Manufacturer and Supplier of a large range of Nipoflange in several dimensions and specifications which is an amalgamation of a nipolet and a weld neck flange. The Nipoflange is a combination of a Weld Neck flange and a supposedly Nipolet. On the run pipe side, a Nipoflange is designed to sort of a Forged Weldolet. which means the branch connection on the run pipe side is a welding connection. On the opposite side there it’s a flange connection. The flange connection is designed consistent with the customer’s requirements. A nipoflange almost like ASME B 16.9 or MSS-SP 97 is manufactured from forged material. meaning a nipoflange is a forged fitting without a welding seam. A Nipoflange is used within the pipe industry sort of a nipolet for a 90° branch connection. A Flange-olet (Flange-outlet) is also called Nipoflange, its shape seems like a long weld neck flange. It can be considered a mixture of a long weld neck flange and a nipolet welded with a weld neck flange. These Nipoflange dimensions might be designed as per EN1092, ASME/ANSI B16.5 standard, or other codes. The flange-olet is produced within the forging and machining process, it’s forged material, commonly the flange-olet is an integral forging with no welding seam. the opposite side of the ASME B16.5 Nipoflange connects to a valve or other equipment. These Nipoflange are primarily called branch connections.
