Using Inconel and It’s Applications

Material like Inconel is designed to withstand harsh production environments. Inconel 625 flanges is a product is stronger than stainless steel, as well as maintaining tensile strength in excess of other steels. Testing strength involves tensile properties, corrosion resistance, and even melting reactions. The tensile strength of Inconel 625 is more than two times that of stainless steel, and it can be used in higher operating temperatures (103-160 Ksi).

Its increased chemical resistance makes it ideal for a wide range of applications involving gases and large temperature variations. Inconel 625 Flanges is made from nickel and chromium and resists oxidation. The aerospace, medical, oil, and gas industries are more likely to use Inconel.

5 major applications of Inconel used in industries

The Use of Heat Treatment

When exposed to extreme temperatures, Inconel maintains sufficient strength to support moderate loads, despite its resistance to extreme temperatures. This gives Inconel an advantage over stainless steel alloys, such as 304, 316, and 330 SS, when it comes to heat treating baskets. In the case of harsh thermal treatments, a basket constructed from an Inconel super-alloy will maintain its form better than one constructed from many stainless steel alloys.

The process of extracting oil and gas

Because Inconel can withstand both high temperatures and oxidation, oil and gas extraction companies prefer it. Super-alloy metals, such as Inconel, are ideal for oil and gas production because they can withstand harsh conditions and corrosive gases.

Super-alloy Inconel 625 is particularly suitable for natural gas processing systems. Inconel 625 has high thermal fatigue strength and enhanced resistance to oxidation, making it a popular choice for use in separating removed fluids and in-line steel pipework.

Jet engines

It is routine for jet engines to operate at extreme temperatures while they are in operation. Combustion chambers and cooling methods are not sufficient to influence Inconel 600’s oxidation resistance and tensile strength. When chemical resistance and extreme temperatures are required, as well as in any application where precious metals would oxidize at high temperatures, Inconel is a great choice.

Rapid Variations in Temperature

Rapid temperature fluctuations are often seen in industrial processes that alternate between operations at high and low temperatures. In general, Inconel alloys have good resistance to oxidation at both high and low temperatures, which allows the basket to be used from low temperatures to very high temperatures.

Usage in Salty water

The outstanding resistance of Inconel to sodium chloride (salt) at a variety of temperatures makes it a popular material for maritime applications.  For factories located near the coast or in salty areas, Inconel makes an excellent parts washer material thanks to its anticorrosive characteristics.

Sometimes all the stainless steel is not metallic but are resistant to seawater, knowing these facts should we consider using Inconel is the question.

The benefits of this alloy are primarily related to severe temperatures above 1,000°F, which are not present with grade 316 stainless steel. It would be better to use Inconel than the stainless steel 316 at high temperatures because it’s less prone to oxidation.

Inconel 625 Flanges

Quick guide to Inconel 625 Flanges

Inconel is a nickel-chromium alloy 625 is used for its high strength, excellent, fabricability (including joining), and out-standing corrosion resistance. Inconel belongs to the so-called ‘super alloys’ group, which includes especially austenitic nickel-chromium-based alloys. Temperatures in use vary from cryogenic to 1800°F (982°C).

Inconel 625 is made or processed from the stiffening effect of nio-biumon and molybdenum, its nickel-chromium matrix; thus precipitation do not require hardening treatments. This blend of elements is also responsible for excellent resistance to a wide variety of unusually harsh corrosive conditions, as well as high-temperature effects such as oxidation and carburization.

What are Inconel 625 Flanges

A flange is a device used to connect pipes or tube, valves, pumps, and other pieces of equipment to develop a piping structure. It also allows for simple washing, inspection, and alteration. Flanges are welded or screwed. Flanged joints are created by bolting two flanges together with a gasket between them to provide a seal.

One of  benefits of Inconel is its potential to be used under severe environments. Such extremes are either high temperatures or heavy pressure. This is because when Inconel is exposed to very high temperatures, it forms a very stable oxide layer, which prevents the metal’s surface from further corrosion.

High temperatures or high pressure are examples of those extremes. This is due to the fact that when Inconel is exposed to very high temperatures, it forms a very durable oxide coat, which protects the metal’s surface from further corrosion.

Inconel flanges have great oxidising and decreasing content of corrosion resistance, making them ideal for a variety of high corrosive applications. It is used in chemical processing applications due to its high resistance to sulphuric acid and hydrochloric acid. Inconel valve flanges are widely found in fuel and water pipelines. It has a longer operating life and is therefore less expensive to maintain.

Inconel 625 flanges are in a variety of configurations, including 

  • Slip on Flange
  • Weld Neck Flanges
  • Flanges Reduction
  • Socket Weld Flange
  • Threaded Flange
  • Blind Flanges
  • Lap Joint Flanges, and more.

Inconel 625 Flanges are the most prominent and durable corrosion-resistant alloy. After being diluted and partly oxidised, it has a very high corrosive resistance. They are limited, and the fastener are only produced in larger diameters.

Benefits of Inconel 625 Flanges

  • Corrosion resistance
  • Mechanical properties at high temperatures is excellent
  • Suitable for sulphuric and hydrochloric acid environments.
  • Outstanding resistance to stress corrosion cracking.

Applications Inconel 625 Flanges

Inconel 625 flanges are used in Chemical industries, Oil and gas factories, gas processing industries, petrochemical industries, food processing industries, sugar industries, power generation industries, and fertiliser industries etc.

Inconel 625 Flanges has a range of applications that has a wide and is widely used for high performances equipment. It is popular to find it in chemical and pressure vessel, pump motor shafts, steam turbine and also in Turbine blades, combustors and seals in oil and gases industries.

When it comes to highly critical uses, 625 Flanges is also one of the key components of nuclear pressurised water reactors.

Inconel 625 Flanges are more durable and robust flanges which are mostly applicable.
