Hastelloy Orifice Flanges Supplier

What is Hastelloy alloy?

Hastelloy contains molybdenum, nickel, and chromium. Hastelloy is a term that refers to a group of corrosion-resistant metal mixtures that are based on nickel. Hastelloy has a special set of characteristics that give them significantly stronger corrosion resistance capabilities than traditional alloys. Among the various alloy flanges, Hastelloy Orifice Flanges are considered to be the most valuable ones. These alloys are characterized by their unique structure and excellent resistance to abrasion and corrosion. These alloys are known for their excellent oxidation resistance, resistance to pitting corrosion, and good electrical resistivity. They also display excellent ductility at high temperatures. Their welding and forming properties are also very good. The combination of these attributes makes them ideal for various applications.

What are Hastelloy Orifice Flanges?

Orifice flanges are known as orifice flanges because they are used with an orifice flow meter. The primary purpose of an orifice meter is to analyze the flow rate of gases or liquids through a pipe. These orifice flanges are always used in a set of two. The orifice contains two flanges, Orifice plate Gaskets, pressure taps, and a jackscrew hole with two jackscrews. These orifice flanges are available in various types like slip-on, weld neck, and Slip-on. A unique type of plate called an orifice plate has a hole in the middle that generates a pressure drop that can use to gauge the flow rate. This orifice plate is not interchangeable. Our company offers these flanges has a greater service life, and its maintenance cost is good.

The Advantages of Hastelloy Orifice Flanges are:

  • Immune to corrosion.
  • It is ideal for sulphuric and hydrochloric acid environments.
  • It has outstanding mechanical properties at high temperatures.
  • High resistance to stress corrosion cracking.

Applications of Hastelloy Orifice Flanges:

Hastelloy Orifice Flanges can be used in many applications, but they are especially useful in sulphuric or corrosive environments. The alloys have excellent corrosion resistance, are immune to abrasion, and resist stress corrosion cracking like Hastelloy Ring Type Joint Flanges. Their oxidation resistance is good, but they can withstand temperatures up to 2200 degrees F.

  • Chemical Industries
  • Fertilizer Industries
  • Sugar Industries
  • Power Generation Industries

The alloys have very good weldability and are easy to work with. They can be welded using various methods, including a shielded metal arc, a submerged arc, or a conventional weld. They are not recommended for welding with Oxyacetylene. These alloys can be used for a variety of applications in the field of chemical processing. They are utilized in the field of flue gas desulfurization as well. Their excellent corrosion resistance and good localized corrosion resistance make them ideal for these applications.
