Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials.

• Reducing flanges are used in pipe-to-pipe connections.
• Reducing flanges are a little easier to bolt up than non-reducing flanges.
• They provide the most perfect solution when you need to connect different size flanges.
• These flanges are available in all types and pressures.
• Reducing flanges are fixed by welding, gluing or clamping flanges of equal dimensions provided with different connecting pieces.
• They offer the simplest and least expensive method of mating two different sized flanges.
