Weldo / Nipo Flanges

Trimac Piping Solutions is a well-known manufacturer and supplier of Weldo / Nipo Flange in various sizes and specifications. These flanges come in a range of grades, sizes, and standards. In the piping business, a nipo flange is commonly utilised. It’s a hybrid of nipolet, weldolet, and the welding neck flange. The majority of these are 90° branch connections. The nipolet and weldolet are not made in one piece and are not welded. Because these flanges help to maintain pressure, most companies prefer to use SS Nipo Flange. It’s a ring or disc that’s affixed to the pipe that can provide it more strength and support. Bolts link the flanges to the pipe ends, which is screwed or soldered. A gasket is installed between two flanges to provide a firmer seal. On a branch connection, a Carbon Steel Nipo Flange is used.

The Alloy Steel Nipo Flange is utilized when corrosion resistance and lightweight are desired. Nipoflange Class 150 is a low-pressure flange. Distinct alloys, such as Inconel Nipoflanges and Hastelloy Nipo Flanges, have different qualities and applications.

Rajendra Industrial Corporation specializes in high-pressure, large-diameter, high-yield, and specialized flange manufacture. Stainless Steel Weldo Flanges are made, supplied, and stocked from excellent structural steel such as Carbon Steel, Alloy Steel, and Stainless Steel. These Flanges are by far the most robust and are made to fit a variety of pipe sizes. The majority of our flanges are forged steel, with a small percentage machined from bar stock. The forged construction provides increased strength and durability for long-term use in the application.
