About
Copper Alloy Flanges
Product overview combined with Copper Alloy material context for project selection.
Our integrated facilities include facilities for cutting, forging, ring rolling and machines with CNC lathes, CNC drilling, high capacity forging press and mobile manipulator for making big diameter forged round bars. We also have an in-house heat treatment shop and well equipped laboratory facilities for ensuring the quality of our products.
Manufacturing note
The Nipo Flange is a combination of a Welding Neck flange and a supposedly Weldolet or Nipolet. The branch connection on the run pipe side is a welding connection. On the other side, it has a flange connection. A flange connection can be designed according to customers’ requirements. Nascent fittings is a well-known Manufacturer & Exporter of a comprehensive range of Weldo/Nipo flanges in a variety of dimensions and specifications. Our offered Weld Flanges body is made in excellent Forgings, using the premium quality raw material and sophisticated technology by our expert professionals. The offered range of Weld flange and Nipo flange is available in various specifications and designs and used in Branch connections. To fulfil varied client needs, the series can be offered in numerous thicknesses, check Weldo Flange Sizes before order as per requirement. Because these flanges aid in pressure retention, the majority of industries prefer to use Weldo Flange / Nipo Flange.
