Alloy 625 Slip On Flanges & ASTM B564 UNS N06625 material manufacturer in India
What is Inconel 625 Flange?
The Inconel 625 is an abundantly used alloy material used in a wide range of industries. They are capable of handling mixed acids in both oxidizing and reducing environments. The Inconel 625 Flanges can withstand severely corrosive environments- they are resistant to general corrosion, pitting, and crevice corrosion. The material is prone to work-hardening, and hence it is essential that low cutting speeds are used on the material and also, the cutting tool should be kept engaged all the time.
Different types of Inconel 625 Flanges are available in the market. They are used for different purposes according to their structures. For example, the Inconel 625 Blind Flanges are used for blocking the flow whereas the Inconel 625 Slip-On Flanges are used in piping connection with low pressure and lesser risk of leakage.
The Inconel 625 Flanges are basically made of a chromium-nickel alloy that can resist corrosion. It consists of several other elements in the alloy which enhances its mechanical and physical properties. The flanges possess a very high tensile strength of 930 MPa, and 517 MPa is its minimum yield strength. It comes with a melting point of 1350 degrees C. Thus, it can be said that the flanges are used for high-temperature and stressful applications. The flanges are made following international standards like ANSI, ASME B16.5, B16.47 and others.
The Inconel 625 Flanges comes with various pressure classes that range from 150 to 2500, and the pressure number is between PN6 through PN64, and so on. Depending on the type of flange in use, they can be used in critical industries like pharmaceuticals, speciality chemicals, power generation, off-shore oil drilling, gas processing, etc.The 625 alloy shows excellent corrosion resistance properties in various medias, including environments that are highly acidic or in water. This is why the Inconel 625 Flanges are popularly used in the nuclear and marine industries.
The benefits of the Inconel 625 Flanges would include:
- Corrosion resistance
- Excellent mechanical properties at elevated temperatures.
- Gives great performances even in different acidic environments.
- Excellent stress corrosion cracking resistance capabilities.
ASTM B564 UNS N06625 Weld Neck Flanges v.s Alloy 625 Ring Type Joint Flange
The ASTM B564 UNS N06625 material is a nickel-molybdenum alloy that is known for its high strength and excellent corrosion resisting properties. The ASTM B564 UNS N06625 Weld Neck Flanges are high hub flanges that are mostly used for relocating the stress to the pipes. It also ensures to decrease a high stress of the concentration at the bottom of the pipe. The ASTM B564 UNS N06625 Weld Neck Flanges are mostly used in all types of severe and critical applications.
The Alloy 625 Ring Type Joint Flange is made of the same alloy and hence they oo are used in similar high pressure and high temperature environments. They are basically used when a metal-to-metal seal is required by the two mating flanges.
Nickel 625 Blind Flange v.s the ASME B16.5 Inconel 625 Slip on Flange
Both the Nickel 625 Blind Flange and the ASME B16.5 Inconel 625 Slip on Flange are made of the same alloy material and hence they are used in similar environments and also across similar industries. However, due to the difference in their structural configuration, their functions are quite different.
The blind flanges have no bore and they are used at the end of a pipe, pressure vessel or valve opening. They help in obstructing a segment of the pipe or nozzle that is not under use.
The slip on flange looks like a ring placed over the end of a pipe. It is then double welded, from both inside and outside to join with the pipe. They are used for not so critical applications for different fluid pipelines.
Why is DIN 2.4856 Flanges so hard to machine?
The Inconel 625 material has a very high tensile strength and high yield strength at high temperatures, which is much higher than normal stainless steel grades. This is why the DIN 2.4856 Flanges are so hard to machine.
