Stainless Steel Threaded Flange
Stainless steel threaded flanges are pipe fittings designed for connecting pipelines, valves, or equipment via threaded joints. Manufactured from high-quality stainless steel (e.g., 304, 316, 316L), they combine high strength, corrosion resistance, and high-temperature tolerance. Their design integrates the stability of flanges with the convenience of threaded connections, making them ideal for low-to-medium pressure systems, particularly in applications requiring frequent disassembly or limited space.
Structure
1. Material: Austenitic stainless steel (304/316/316L, etc.), with optional custom grades.
2. Connection Type: Internal or external threads, compliant with standards such as NPT , BSPP, or G-thread
3. Face Type: Flat face (FF), raised face (RF), or custom configurations.
4. Size Range: Nominal diameter (DN) from DN15 to DN4000 with pressure ratings spanning PN10 to PN40 (or Class 150-300).
Key Features
1. Corrosion Resistance: Suitable for acidic, alkaline, saline, humid, or high-temperature environments.
2. Leak-Free Sealing: Threads paired with gaskets or sealants ensure reliable joint integrity.
3. Easy Installation: No welding required, reducing labor and installation costs.
4. Reusability: Threaded design allows for easy disassembly and maintenance.
5. Surface Finish: Acid pickling, polishing, or sandblasting for enhanced aesthetics and contamination resistance.
Applications
- Chemical/Petrochemical: Corrosive fluid and gas pipelines.
- Food/Pharmaceutical: Hygienic piping systems compliant with GMP standards.
- Water Treatment: Seawater desalination, water supply, and drainage.
- Marine/Energy: Saltwater-resistant piping in ships and offshore platforms.
- HVAC: Hot/cold water circulation systems.
Technical Specifications
- Standards: ISO, ANSI/ASME B16.5, DIN, JIS, GB, etc.
- Working Pressure: PN16 to PN40
- Temperature Range: -20°C to +200°C (316L withstands higher temperatures).
Installation & Maintenance Guidelines
1. Installation:
- Apply thread sealant or PTFE tape to prevent leakage.
- Avoid over-torquing to prevent thread stripping or flange deformation.
2. Compatibility: Ensure thread standards and pressure ratings match connected components.
3. Maintenance: Regularly inspect seals and clean threads to prevent corrosion buildup.
