What are Alloy Steel Forged Fittings?
Alloy Steel Forged Fittings are pipe connection components manufactured through hot forging and precision machining. They are used to connect pipes, valves, and equipment in systems that demand exceptional mechanical strength and corrosion resistance.
Made from heat-treatable alloy grades like A182 F5, F9, F11, F22, and F91, these fittings are engineered to handle high-pressure applications, thermal cycling, and aggressive media, making them ideal for industrial use in refineries, thermal power plants, and chemical industries.
Key Features of Alloy Steel Forged Fittings
- High Mechanical Strength: Withstands high internal pressures without deformation.
- Superior Resistance to Heat and Corrosion: Suitable for high-temperature, aggressive service.
- Excellent Impact and Fatigue Resistance: Ideal for dynamic loading and vibration-prone systems.
- Leak-Proof, Precision Fit: Manufactured to tight tolerances for secure, efficient assembly.
- Multiple Connection Types: Available in threaded (NPT/BSPT), socket weld, and custom connections.
- Tested and Certified: Compliant with global standards (ASME, ANSI, DIN, EN).
