Hastelloy Flanges Manufacturer and Supplier In India
Hastelloy is a trademarked name for a family of high-performance, corrosion-resistant nickel-based alloys. These alloys are known for their excellent resistance to a wide range of corrosive conditions, making them highly suitable for applications in aggressive chemical processing, petrochemical, and other industries where corrosion resistance is very necessary. Hastelloy flanges are specialized flanges made from Hastelloy alloys. These flanges are manufactured to connect pipes, valves, and other equipment in a piping system while providing the same corrosion resistance as the base Hastelloy material. Hastelloy flanges are parts used in piping systems to simplify the assembly, disassembly, and maintenance of pipelines. They are normally circular discs with openings in the center to hold the pipe or valve they are attached. These flanges are made from various grades of Hastelloy alloys, such as Hastelloy C-276, Hastelloy C-22, and Hastelloy B-2, to match the specific corrosion resistance requirements of the application. Some of the advantages of hastelloy flanges are high corrosion resistance, high strength, excellent durability and low maintenance. Various applications where these flanges are used are pollution control, offshore and marine, semiconductor industry, petrochemical industry and many more.

Weld Neck Hastelloy flanges are commonly used in high-pressure and high-temperature
applications where the risk of leakage is high. They are often used in critical applications
where the integrity of the pipeline is paramount, such as in the oil and gas, chemical, and
petrochemical industries.
Slip-On Hastelloy flanges are typically used in applications where the pipeline needs to be
disassembled and reassembled quickly. They are commonly used in chemical, petrochemical, and
oil and gas industries for low-pressure applications.The Slip-On Hastelloy flange is slid
over the pipe and then welded.
Threaded Hastelloy flanges are easy to install and can be used in applications where
disassembly and reassembly are required. They are commonly used in plumbing and heating
systems, as well as in the chemical and petrochemical industries for low-pressure
applications.
Blind Hastelloy flanges are typically used in applications where future access to the
pipeline is not required, such as in dead-end piping systems or for testing and inspection
purposes. They are also commonly used in the oil and gas, chemical, and petrochemical
industries The Blind Hastelloy flange is bolted to the end of the pipe or fitting.
Socket Weld Hastelloy flanges are commonly used in high-pressure and high-temperature
applications, as they provide a strong and reliable connection between pipes or fittings.
They are often used in the chemical, petrochemical, and oil and gas industries The Socket
Weld Hastelloy flange.
The orifice plate is placed between two Orifice Hastelloy flanges and held in place by bolts.
The flow of fluid through the pipeline is restricted by the orifice plate, which creates a
pressure drop that can be measured to determine the flow rate.Orifice Hastelloy flanges are
available in various sizes and pressure ratings.
Features of Hastelloy Flanges
Another key feature of Hastelloy flanges is their durability, which allows them to withstand the
rigors of industrial applications and ensure long-lasting performance. They are also easy to install
and can be easily aligned with pipes and fittings, making installation quick and hassle-free.
Hastelloy flanges are highly versatile and available in a range of sizes, pressure ratings, and
types, making them suitable for a wide range of industrial applications. Additionally, due to their
excellent corrosion resistance and durability.
