Inconel Flanges: Types and Applications


What Are Inconel Flanges?

Inconel flanges, such as Inconel 600 Flanges , 601, 625, 686, 718, and 725 flanges, are nickel-chromium-molybdenum alloys known for their strong strength at high temperatures and corrosion resistance.

Various Types Of Flanges

The high alloy content of Inconel flanges allows them to withstand a wide range of corrosive environments. In moderate environments like the atmosphere, seawater, basic salts, and alkaline media, Inconel 600 flanges are basically unaffected. In more severe corrosive circumstances, the combination of nickel and chromium provides resistance to oxidizing chemicals, while the high nickel and molybdenum levels provide resistance to non-oxidizing environments.

  • A welding neck flange is made of Inconel and features a long tapered hub that may be welded with a pipe. It is used to demand an unrestricted flow of the fluid carried by the piping system in high-pressure and high/low temperature applications.
  • Long weld neck flanges are the same as weld neck flanges, except that the neck (tapered hub) is longer and serves as a boring extension.
  • Two fillet welds, one inside and one outside the flange cavity, secure the slip-on flange to the pipe or fittings.

Threaded flanges are attached to pipes by screwing the pipe into the flange without the use of seam welds.

  • Flanges with Socket Welds

A single fillet weld on the flange’s outer edge is used to link it to pipes.

  • Lap Joint Flanges

have a flat face and must be used with a stub end at all times Lap joint flanges are identical to slip-on flanges in appearance, with the exception of the radius at the flange face/bore junction, which allows the flanged portion of the stub end to pass through.

  • Blind Flanges

As a result of system pressure and required attachment pressures, it must withstand high mechanical stress. Because blind flanges may be rapidly unbolted to allow the operator to execute operations within the pipe’s terminal end, they provide easy access to the pipeline.

Inconel flanges are used in the following applications:

Inconel is utilized in a wide range of applications, although it is most commonly found in high-performance equipment that is extremely trustworthy in severe environments. It’s also utilized in the chemical, pump, and power industries, as well as in the gas and oil industries.

Nickel Alloy and Inconel are used in a variety of high-pressure applications, ranging from nuclear power to spectator sports. It’s realistic to assume that for many engineers attempting to create a high-functioning and trustworthy product, it’s an important material grade and a simple choice.

Inconel is one of the strongest and most durable metals on the market, and it may be used in a wide range of applications.

The Flanges are appropriate for high-temperature applications because they maintain their strength across a wide temperature range. These are offered at exceptionally low prices to key clients in a variety of diameters, wall thicknesses, and sizes.
