Orifice Flange Forged Stainless Steel Flange 304/316L
The Standard Pressure Orifice Flange manufactured from forged 304/316L stainless steel represents a precision-engineered flow measurement component designed for critical process applications. These flanges are specifically engineered to provide accurate, reliable, and repeatable flow measurement in industrial piping systems while maintaining structural integrity under varying pressure conditions. Manufactured through advanced forging processes and precision machining, our orifice flanges ensure optimal performance in corrosive and high-purity applications where material integrity and dimensional accuracy are paramount.
