What is Nippo Flanges?
Weld neck flanges, weldolets, and nipolets are generally combined to make Nippo Flanges. On one of the run pipe's sides, there are branching connections that serve as the primary welding connection, and on the other side, there is a flanged connection. According to the specific needs, in accordance with standards like DIN, ANSI, etc., the design of the flanged connection is tailored.
There are three types of Nippo Flanges: forged, threaded, and screwed. Their manufacturing process combines machining, heat treatment, and forging. They come with a variety of features, such as raised faces, flat faces, faces with ring-type joints, etc. The settings in which the Nippo Flanges can be utilised vary depending on the material grade used in their manufacture. They are typically found in equipment for the petrochemical industry, bitumen upgraders, heavy oil refineries, etc. In nuclear power reactors, seamless variations are frequently employed. They come in a variety of pressure ratings, up to 2500#.
The reinforced fittings are frequently connected together using Nippo Flanges as well. They come in a variety of sizes, which typically run from 18" to 4". They have beautiful finishes and are corrosion-resistant. Customers can get Nippo Flanges in a variety of grades, sizes, and designs to suit their needs. It is a high-performing, cost-effective flange that is long-lasting and easy to maintain.

What is Weldoflange?
A weldoflange is a flange that combines the characteristics of a welding outlet and a weld neck flange. In order to increase their strength and hardness in the design, they are typically built from a single metal piece, without any welding. In other words, the welding outlet and the weld neck flange were produced as a single unit. These flanges function as 90-degree branches from the run pipe from branched connections. They must adhere to many standards, including the pressure ratings and those set forth by ANSI, ASME, etc., in order to perform at their peak levels. Weldoflanges are employed to satisfy a variety of needs because of their remarkable performance. They are available in different material grades and thus are used in different environments accordingly. Common uses of Weldoflange are in oil and gas pipeline, chemical industry, plumbing, water supply system, structural pipes, etc.

Difference Between Nipoflange vs Weldoflange
The only distinction between the Nipo Flange and the Weldoflange is that the Nipo Flange has branching connections on one side that are at a 90-degree angle from the run pipe and a flanged connection on the opposite side that joins the main pipe or other devices. Weldoflange, on the other hand, only has branched connections with branches that are 90 degrees off the run pipe. Other than this, the workings, designs, etc. of both flanges are comparable.

Where to we Use Nippo Flanges
The Nippo flange is available in a variety of material grades for usage in various applications. For branching connections, for instance, carbon steel nip flanges are utilised; however, if an alloy steel nipo flange is needed, it can be made light-weight or resistant to corrosion. Additionally, nickel alloy reinforced nipo flanges are employed in a variety of applications, including equipment for oil refineries, cooling systems, and sea water equipment. The strength and pressure requirements of the nipo alloy are determined by its composition, which also serves to clarify where they should be employed.

What are the standard of Weldoflange
Weldoflange's dimensional standard is established in accordance with special drawings, such as ANSI B16.5 and ANSI B16.47 Series A & B. They come in numerous classes ranging from 150 LBS to 2500 LBS, as well as different DIN specifications. Additionally, they have many BS standards, including BS10, BS1560, and BS4504.
