A Inconel flange is a device that is used to connect a valve, pump, pipes, and other piping equipment. The Inconel flanges are nickel-chrome-based superalloy grade that is seen in refineries and oil fields. These Inconel pipe flange are characterized by enhanced corrosion and oxidation resistance properties. The flanges are divided into different classes, each having its own features.

Inconel flange are non-magnetic alloy that possesses superior strength and showcases outstanding creep resistance in harsh environments. The Inconel weld flanges provide stability to the devices during the vigorous movement of flow in the system. These flanges work well in different pressure and temperature conditions. Inconel hot forged flange showcases enhanced mechanical properties and strength compared to the 600 and 601 classes of Inconel. These flanges can easily work in low-temperature conditions and possess a melting point between 2500 to 2600 degrees F. Our company is an Inconel Flanges manufacturer in India who has a vast stock of inventory of flanges that are available in different sizes to meet all customer demands.

In UAE, Which Inconel Pipe Flange Types Mostly Use?

1.) The Inconel slip on flange is easy to install as they are slid and welded to the pipe using one or more fillet welds. These flanges are common in the oil and gas industry due to their economic cost.

2.) A Inconel socket weld flange possesses the same static strength as a slip-on flange and uses a socket to lock in the pipe and weld it. They are recommended for low-pressure and temperature applications.

3.) The Inconel blind flange is designed without a hub and is primarily used as blanks. The blanks help cut the flow of media in different hydraulic systems. They can handle high-pressure and temperature applications.

4.) Inconel threaded flanges are screwed flanges that have threads that allow them to screw onto subsequent grades. They have a simple attachment and detachment process.
