ASME Orifice Flange for Instrument Piping

Our ASME standard Orifice Flanges are specially designed for instrument piping systems, widely used for flow measurement and control in petrochemical, oil‑gas and power‑generation industries. These flanges are hot‑forged from premium carbon steel and stainless steel materials, manufactured strictly in accordance with ASME B16.5 standards.

Available in multiple pressure classes and full size range, orifice flanges come with standard tap holes for mounting pressure‑measuring instruments. Different sealing types including RF and RTJ can be customized to match various working conditions. Every product goes through heat treatment, dimensional check, chemical analysis and non‑destructive inspection to ensure stable performance under high‑pressure service.

We support both standard stock items and non‑standard custom processing. As a professional forging manufacturer, we accept bulk export orders. Complete test documents can be provided. Reliable quality and short lead‑time help global clients meet instrument piping project demands efficiently
