Stainless Steel Orifice Flanges Manufacturer and Supplier In India
Stainless steel orifice flanges are specialized pipe flanges manufactured for measuring the flow rate of fluids in pipelines and controlling fluid flow. These flanges have a unique quality: a concentric orifice plate, which is a thin metal disk with an accurately sized hole (orifice) in the center. Stainless steel orifice flanges are typically made from stainless steel materials known for their corrosion resistance and toughness. They are defined by the presence of an orifice plate sandwiched between two flanges. The orifice plate has an accurately machined hole that acts as a flow restriction, allowing for flow measurement and control. Orifice flanges are available in various pressure ratings, sizes, and orifice sizes to fit in various applications. The applications are flow measurement, fluid control, process industries, research and testing, chemical processing, utilities, power generation, and many more usages.

- Socket Weld (SW) Orifice Flanges: Our stainless steel SW orifice flanges have a socket or hollow area where
the pipe end is inserted and welded.
- Slip-On (SO) Orifice Flanges: Our SO orifice flanges have a flange face that extends beyond
the pipe, allowing for easy adjustment and setup.
- Weld Neck (WN) Orifice Flanges: Our WN orifice flanges have a coned neck that extends from
the flange, that helps in easy welding and providing support.
- Ring Type Joint (RTJ) Orifice Flanges: RTJ orifice flanges manufactured by us feature a groove shaped into
the flange face, where a metal ring gasket is placed.
- Flat Face (FF) Orifice Flanges: FF orifice flanges supplied by us have a flat face without a raised
surface.

Uses of Stainless Steel Orifice Flanges
The Stainless Steel Orifice Flanges manufactured by us are mainly used with orifice plates to measure fluid flow rates in pipelines. The orifice plate creates a narrowing in the flow, which leads to pressure drop across the plate that is used for calculating the flow rate. The orifice flanges supplied by us play an important role in maintaining exact control over fluid processes. The metric stainless steel flanges have full control over certain parameters such as temperature, pressure, etc. by accurately measuring flow rates.

Industries served by Stainless Steel 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.
Oil and Gas Industries
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.
Petroleum Industries
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.
Shipbuilding in India
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.
