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.

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.
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.
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.
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.
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.
The oil and gas industry includes a wide range of from drilling and production to refining and marketing. Some of the major players in this include oil and gas companies, service providers, equipment.
In the drilling process, stainless steel is used to make drill bits, pipes, and other equipment that must withstand high pressures and temperatures. Stainless steel is also used to make pumps, valves, and fittings for the transportation.
In storage applications, stainless steel is used to make tanks and containers that can safely store corrosive and hazardous chemicals. It is also used in piping systems for chemical transfer and distribution chemical industry.
