D J Metal Industries stands out as a premier manufacturer, supplier, and exporter of Orifice Flanges crafted from top-notch raw materials. These flanges serve as substitutes for standard pipe flanges when an orifice plate or flow nozzle is in use. It’s important to note that the orifice plate is a distinct component and is not included as part of the flange assembly. Widely applied across various industries, these flanges come in a range of sizes, grades, specifications, and thicknesses to meet specific client requirements. D J Metal Industries offers these flanges at competitive market rates.

The purpose of an SS orifice flange is to enable the measurement of gases or liquids within a pipeline. When installed in a line, an orifice plate is secured between two flanges, forming an assembly known as an orifice flange union. Jack-screws within this assembly facilitate the easy removal of the orifice plate. The orifice plate, functioning as a metering device, is a thin plate featuring a central, concentric, square-edged circular hole. To measure the pressure difference across the orifice, two pressure tap-holes are drilled into each flange.

What are Stainless Steel Orifice Flanges?

Stainless Steel Orifice Flanges are specialized flange components designed for the purpose of metering gases or liquids within a pipeline. These flanges are crafted from stainless steel, a corrosion-resistant material known for its durability and suitability for various industrial applications. The key features of Stainless Steel Orifice Flanges include the ability to accommodate an orifice plate, which is clamped between two flanges during installation.

The orifice plate, functioning as a metering device, consists of a thin plate with a central, concentric, square-edged circular hole. This hole regulates the flow of gases or liquids, allowing for precise measurement. The entire assembly, comprising the orifice plate clamped between the flanges, is referred to as an orifice flange union.

Stainless Steel Orifice Flanges are equipped with jack-screws within the assembly, facilitating the easy removal of the orifice plate for maintenance or adjustments. Additionally, two pressure tap-holes are typically drilled into each flange to measure the pressure difference across the orifice, providing essential data for flow rate calculations.

These flanges are widely used in various industries where accurate measurement of fluid flow is crucial, and the corrosion-resistant properties of stainless steel are advantageous.
