Stainless Steel Reducing Flange

 

The stainless steel reducing flange is a forged, pressure-rated flange designed to connect pipes of different nominal diameters. Its outer diameter, bolt hole configuration, and sealing face dimensions comply with ASME or EN standards, while the center bore is precision-machined to match the smaller pipe diameter, enabling a secure transition between pipe sizes within the piping system.

Highly Reliable Forged Structure
Utilizes an integral forging process instead of casting or welded fabrication, ensuring continuous metal grain flow. This enhances compressive strength and fatigue life, making the product suitable for Class 2500 high-pressure systems and long-term operational conditions.

 

Standardized System Compatibility
Manufactured in strict accordance with ASME/EN standards, allowing for direct compatibility with standard piping flange systems. This eliminates the need for on-site machining, thereby reducing installation time and engineering risks.

 

Optimized Sealing System
Sealing surfaces are precision-machined via CNC, with the Raised Face (RF) roughness controlled within the 125–250 AARH range to ensure full compatibility with standard gasket systems (such as spiral-wound or metal gaskets).

 

Full Process Traceability
Each product is marked with a Heat Number and backed by comprehensive production records, enabling full traceability back to the raw material heat/batch.
