ASTM B564 UNS N08825 Blind And Weld Neck Flange Manufacturer In India.

Incoloy 825 Flanges


The corrosion rate of Incoloy 825 Flanges in sulfuric acid is higher than the corrosion rate of ASTM B564 UNS N08825 Lap Joint Flanges because of small amounts of molybdenum and copper. SB 564 UNS N08825 Weld Neck Flanges has lower corrosion rate in nitric acid because of larger amount of chromium.

 

What are Incoloy 825 flanges?

Incoloy 825 is an allot of material made from nickel in combination with other elements. Flanges made from this material is termed Incoloy 825 flanges. They are used in high heat and wear and tear applications since the material can withstand such strenuous situations in the best possible manner. Being resistant to Chlorine ions, these flanges can be used in reductive environments where the concentrations of sulphuric and 0hosphoric acids are high. Besides, it can tolerate a much high temperature, enabling it to be used for a wide range of applications. Thanks to their excellent mechanical properties, the Incoloy 825 flanges are preferred by several construction industries.

What is din 17750 flange?

Flanges manufactured from wrought nickel and alloys are said to have the DIN 17750 specification. It is a special class of all0y where the nickel content is so high that it can withstand both chemical and mechanical damage and wear and tear. The manufacturers can produce several types of flanges with this material, starting with weld neck to slip-on and blind flange.

Things to check before finalization of your Alloy 825 Flange manufacturer in India

There are several manufacturers from where one can find the alloy 825 flanges. But not all of them are suitable for business which is why choosing them wisely is imperative. Below mentioned are some points that will help one to make the correct choice!

  • Start with the experienced manufacturer who has been in the market for a long time.
  • Check the reviews for the concerned manufacturer.
  • Make sure to go through the licenses and certifications.
  • Check the material grade and hardness before purchasing the flanges.
  • Please go through the product types to check whether your required flange type is available with them or not.
  • Make sure to ask for manufacturing and chemical composition documents for the flanges.
  • Check the price and always go for manufacturers offering standard prices.
  • Lastly, never settle down with anything less than the best Incoloy 825 flanges.

 

Incoloy 825 Flange is a nickel-iron- chromium material with copper, titanium, and molybdenum. Inconel 825 Flanges can survive 1600 to 2150° F. Alloy 825 Flanges material has good weldability while connecting pipes together. UNS N08825 Blind Flanges have similar properties compared to Alloy 800 Flanges but has improved resistance to aqueous corrosion. B564 N08825 Slip On Flanges remain sustainable during extended exposure to high temperatures.

ASTN B424 UNS n08825 flange hardness

Since the flanges are extensively used in piping and pressure-related environments, it is important to check the hardness of the ASTN no8825 Incoloy 825 alloy using which the flanges are manufactured. This particular material is hard enough to withstand mechanical corrosion, high pressure and low to moderately high temperatures with ease.

Advantages of Incoloy 825 Flanges

Incoloy 825 has a high nickel concentration in addition to chromium and other such elements. Perhaps this is why the material is so hard and can withstand mechanical and chemical corrosions and extreme physical conditions. Following are the major advantages of the Incoloy 825 flanges:

  • These flanges have improved resistance against aqueous corrosions caused by the flow of any fluid-like substances.
  • These can be used in both oxidative and reductive environments having high concentrations of chlorine and hydrogen ions.
  • They are capable enough to withstand mechanical pressure exerted by the flow of fluids through constricted pipes.
  • The Incoloy 825 material has a high hardness which is why the flanges can withstand surface corrosion.

UNS N08825 Flange Face Types and uses

There are six types of flange faces

  • Raised face flange- A RF flange has a protruding hub, which allows it to seal the gaskets by concentrating pressure on the mating flanges to create a strong seal.
  • Flat face flange- FF flanges are used in low-pressure systems as the contact surface has the same height as the bolting line.
  • Ring joint flange- A RTJ flange helps in creating a metal-to-metal seal between different mating flanges. They are used in high-pressure and temperature systems.
  • Lap joint flange- This flange has a flat face which is not used to seal the joint. It is utilized to simply host the back of a stub end.
  • Tongue and groove flanges- Both these flanges fit in each other and effectively seal the flange.
  • Male and female flange- These two flanges are similar to the tongue and groove flanges. Here the male face is ¼ high while the female face is 3/16th deep.

Alloy 825 slip-on flanges properties

The simplest flange form is the slip-on. It is made from a wide range of materials, including alloy Incoloy 825, whose properties are:

  • Resistance to low to moderately high temperatures
  • Ability to withstand oxidation and reduction when subjected to different chemical environments
  • Has a high level of tolerance for surface corrosion due to mechanical stress like continuous friction

Alloy 825 weld neck flange uses

Flanges are of several types. But the most useful and popular design is that of the welding neck flange, where a tapered pipe connector is welded onto the circular rim of the flange. It helps better connect systems where joints need to be made between a flat and narrow surface. The Alloy 825 welded neck flange can withstand both the low cryogenic temperatures and the moderate-level high temperatures to ensure its resistance to heat. Furthermore, it can easily withstand pressure and surface corrosion which is why it is used in pipe fitting and mating through which corrosive products are meant to be flown.

Incoloy 825 blind flanges application

Unlike other flanges, in the blind flange, no central cut-out area is present. Because of such a unique structure, its applications are as follows:

  • The blind flange is used for closing off any pipe or flow construction with the help of threaded nuts and bolts.
  • It is also used for sealing pressure vessel openings.
They have found intensive applications in the testing industry where fluid flow is examined through pipes
