Hastelloy Orifice Flanges Manufacturer and Supplier In India
Hastelloy orifice flanges are a specific type of flange made from Hastelloy alloys, which are known for their outstanding corrosion resistance properties. Orifice flanges are manufactured with a bore (opening) that contains an orifice plate, which is used to measure fluid flow rates or control flow in pipelines. Hastelloy orifice flanges are circular flanges with a central bore (hole) that contains an orifice plate. The orifice plate typically has an accurate opening or aperture, which allows fluid to flow through. The flow rate of the fluid passing through the orifice is measured or controlled by the size of the opening in the plate. These flanges are typically used in flow measurement and control systems. Various applications of these flanges are flow measurement, process control, power generation, pharmaceutical and food processing, HVAC systems and many others.

Types of Hastelloy Orifice Flanges
They are commonly used in high-pressure applications and provide a smooth transition for fluid flow, minimizing turbulence and pressure drop. They are easy to align and install, making them suitable for applications with lower pressure and temperature requirements. They are suitable for high-pressure applications and offer reliable performance in corrosive environments. They are used in applications where periodic flow measurement or isolation is required.
- Weld Neck Orifice Flanges: These flanges have a long tapered hub and a neck that provides reinforcement and strength.
- Slip-On Orifice Flanges: Slip-on orifice flanges have a low-profile design and easily slide onto the pipe.
- Threaded Orifice Flanges: Threaded orifice flanges have internal threads that allow them to be screwed onto threaded pipes or fittings.
- Socket Weld Orifice Flanges: These flanges have a socket weld connection that provides a strong and secure joint.
- Blind Orifice Flanges: Blind orifice flanges are solid disks without a bore. They are used to close off the end of a pipeline or vessel and are often installed as a blanking plate for future orifice installation.

Frequently Asked Questions
What is a Hastelloy orifice flange?
A Hastelloy orifice flange is a specialized type of flange made from Hastelloy alloy, a corrosion-resistant, high-performance nickel-based alloy. These flanges are designed to be used in orifice metering applications for accurate measurement and control of fluid flow.
What types of Hastelloy alloys are typically used for orifice flanges?
Various Hastelloy alloys are used based on the specific application requirements. Common Hastelloy alloys used include C276, C22, B2, and others. The choice depends on factors such as the fluid being handled and the environmental conditions.
Can Hastelloy orifice flanges be used with non-Hastelloy components?
Yes, Hastelloy orifice flanges can be used in conjunction with other materials, such as carbon steel or stainless steel piping, as long as the compatibility of materials is considered, and appropriate gaskets and sealing methods are used to prevent corrosion or leakage.
What are the different types of orifice flange taps?
Orifice flanges can have different types of taps, such as single or dual taps. Dual taps are used for more accurate measurement by allowing pressure readings at both the upstream and downstream sides of the orifice plate.
Industries served by Hastelloy Orifice Flanges
In the oil and gas industry, blind Alloy Steel flanges are used in pipelines, storage tanks, and offshore platforms. They are employed for closing off openings during maintenance, repair, or when a branch connection is not required. Petrochemical plants utilize blind Alloy Steel flanges in equipment such as reactors, distillation columns, and storage vessels. These flanges provide a secure and leak-proof seal when closing off unused openings or isolating sections of the process.
