Quantity
The CS 45 WN Flange is a high-integrity forged carbon steel weld neck flange designed for critical pipe joining applications. Manufactured from premium CS 45 material—a medium-carbon steel known for its superior tensile strength and impact resistance—this 1-inch flange delivers exceptional mechanical properties under moderate to high-stress conditions. The Raised Face (RF) configuration concentrates gasket pressure, ensuring a robust, leak-proof seal even in fluctuating thermal and pressure environments.
Engineered to ANSI B16.5 standards, this WN Flange features a tapered hub that transitions smoothly into the pipe wall, reducing stress concentration at the weld joint. The 150LB pressure rating makes it suitable for low-pressure steam, water, oil, and gas services, while the STD wall thickness provides ample corrosion allowance and structural rigidity for long-term service life.
Key Features & Engineering Advantages
- Precision Forged Construction: The CS 45 forging process refines the grain structure, eliminating porosity and ensuring uniform mechanical properties across the hub and face.
- Raised Face Sealing: The RF profile minimizes gasket creep and enhances bolt-load retention, critical for maintaining joint tightness in cyclic operations.
- Quick & Easy Installation: The weld neck design allows for single-pass butt welding, reducing fit-up time and eliminating the need for complex alignment jigs.
- Interchangeable & Standards-Compliant: Fully dimensioned per ANSI B16.5, guaranteeing compatibility with existing Class 150 flanges, valves, and fittings worldwide.
