Product Description

Stainless Steel Threaded Flange

 

Product Description

Our stainless steel threaded flanges are a pinnacle of precision engineering, purpose-built for the seamless connection of pipelines, valves, or equipment through robust threaded joints. Forged from high-quality stainless steel, including grades like 304, 316, and 316L, these flanges exemplify high strength, remarkable corrosion resistance, and exceptional high-temperature endurance. They are a perfect synergy of the enduring stability of flanges and the effortless convenience of threaded connections. This makes them indispensable for low-to-medium pressure systems, especially in scenarios where frequent disassembly or space constraints are prevalent.


Structure
1. Material: Premium austenitic stainless steel (304/316/316L, etc.), with tailored custom grades available to meet your precise requirements.
2. Connection Type: Offers versatility with internal or external threads, meticulously crafted to comply with global standards like NPT, BSPP, or G-thread.
3. Face Type: Choose from flat face (FF), raised face (RF), or bespoke configurations to suit your specific application needs.
4. Size Range: Nominal diameter (DN) spans from DN15 to DN4000, supporting pressure ratings from PN10 to PN40 or Class 150-300, providing unparalleled adaptability.


Key Features
1. Corrosion Resistance: Designed to thrive in environments that are acidic, alkaline, saline, humid, or subjected to high temperatures, ensuring longevity and durability.
2. Leak-Free Sealing: Achieves impeccable joint integrity with threads complemented by gaskets or sealants, guaranteeing a dependable, leak-proof connection.
3. Easy Installation: Simplifies the installation process with no need for welding, thereby significantly reducing labor and associated costs.
4. Reusability: The clever threaded design facilitates easy disassembly and maintenance, offering unmatched convenience and long-term savings.
5. Surface Finish: Enhanced aesthetics and resistance to contamination are ensured with options like acid pickling, polishing, or sandblasting.


Applications
- Chemical/Petrochemical: Perfect for managing corrosive fluid and gas pipelines with steadfast reliability.
- Food/Pharmaceutical: Ideal for hygienic piping systems that align with stringent GMP standards, ensuring safety and compliance.
- Water Treatment: Proven efficacy in seawater desalination and water supply, as well as drainage applications.
- Marine/Energy: Built to withstand saltwater, making them perfect for piping in ships and offshore platforms.
- HVAC: Optimal for hot/cold water circulation systems, delivering consistent performance.


Technical Specifications
- Standards: Conforms to ISO, ANSI/ASME B16.5, DIN, JIS, GB, etc., ensuring compatibility and quality.
- Working Pressure: Effectively ranges from PN16 to PN40, providing flexibility across different applications.
- Temperature Range: Spans -20°C to +200°C, with 316L capable of withstanding even higher temperatures, catering to extreme conditions.



Installation & Maintenance Guidelines
1. Installation:
- Employ thread sealant or PTFE tape to secure leak-proof connections.
- Exercise caution to avoid over-torquing that could result in thread stripping or flange deformation.
2. Compatibility: Double-check that thread standards and pressure ratings are compatible with connected components for optimal performance.
3. Maintenance: Regular inspection of seals and thorough cleaning of threads will prevent corrosion buildup, ensuring longevity.
