Integrally forged ASTM A105N Reinforced Nipoflange and Carbon Steel A350 LF2 Promat Weldoflange manufacturer in India

What is Nippo Flanges?
The Nippo Flanges are basically created by combining a weld neck flange along with a weldolet or a nipolet. There are branched connections on one of the sides of the run pipe which is the main welding connection and on the other side, there is a flanged connection. The design of the flanged connection is customized according to the specific requirements, according to standards like DIN, ANSI, etc.
The Nippo Flanges are available in forged, threaded, and screwed type. Their production technique involves forging, heat treating, and machining. They are available in different types of faces, including the raised face, ring type joint facing, flat face, etc. Depending on the material grade with which the Nippo Flanges are made, they can be used in a wide variety of environments. Usually, they are found in bitumen upgraders, heavy oil refineries, petrochemical industry equipment, etc. The seamless variants are popularly used in the nuclear plants. They are available with different pressure ratings, upto 2500#.
The Nippo Flanges are also used extensively for linking up the reinforced fittings together. They are available in different sizes that generally range from ⅛” to 4”. They come with fine finishes and are also resistant to corrosions. Clients can get the Nippo Flanges in various grades, dimensions and patterns according to their requirements. It is durable, low-maintenance, and a high-performing flange that comes at an affordable price.

What is Weldoflange?
Weldoflange can be described as a flange that possesses the features of a weld neck flange and a welding outlet. They are mostly made of a single metal piece, without any welding, which improves their strength and toughness in the design. This means that the welding outlet along with the weld neck flange are manufactured as a single piece. These flanges work as branched connections that 90 degrees branches from the run pipe. To give the best performance, they should be compliant to different standards like ANSI, ASME, etc., and also the pressure ratings. The Weldoflange is known for its exceptional performance and that is why they are used for meeting various demands. 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
There is only one difference between the Nipo Flange and the Weldoflange, which is for nipo flange one of the sides has branched connections at 90 degrees angle from the run pipe and on the other side there is a flanged connection that connects the main pipe or other devices. However, for weldoflange, it only has branched connections with branches at 90 degrees angle from the run pipe. Other than this, both the flanges are similar in their working, design, etc.

Where to we Use Nippo Flanges
Depending on the material grade of the Nippo flange, they can be used in different applications. For example, the carbon steel nip flanges are used for branched connections, but in case there is a requirement for light weight or corrosive resistive nipo flange, then alloy steel material ones can be used. Also, the reinforced nipo flanges that are made of the nickel alloy, are used in different applications, like sea water equipment, cooling system, oil refinery equipment, etc. The composition of the nipo alloy determines its strength and pressure requirements, which in turn helps to understand where they shall be used.

What are the standard of Weldoflange
The dimensional standard of Weldoflange is determined according to the custom drawings, like ANSI B16.5, ANSI B16.47 Series A & B, etc. They are available in different classes from 150 LBS to 2500 LBS, and various DIN standards. They also have different BS standards, like BS10, BS1560, BS4504.
