Product Description

Stainless Steel Threaded Flange

 

Product Description

Our Stainless Steel Threaded Flanges are meticulously engineered pipe fittings crafted for seamless connections in pipelines, valves, or equipment through the ease of threaded joints. Forged from premium stainless steel such as 304, 316, and 316L, these flanges embody exceptional strength, superior corrosion resistance, and impressive high-temperature endurance. With a design that harmonizes the robust stability of traditional flanges and the convenience of threaded configurations, they are an optimal choice for low-to-medium pressure systems. Ideal in settings requiring frequent disassembly or where space is a premium, these threaded flanges offer unmatched functionality.


Structure
1. Material: Crafted from austenitic stainless steel grades like 304, 316, and 316L, with possibilities for custom grades tailored to specific needs.
2. Connection Type: Featuring versatile internal or external threads, adhering to standards such as NPT, BSPP, or G-thread for secure and adaptable connections.
3. Face Type: Options include flat face (FF), raised face (RF), or bespoke configurations to meet diverse application requirements.
4. Size Range: Available in nominal diameters (DN) from DN15 to DN4000, accommodating pressure ratings from PN10 to PN40 or Class 150-300, ensuring wide-ranging applicability.


Key Features
1. Corrosion Resistance: Engineered to thrive in acidic, alkaline, saline, humid, or high-temperature environments, ensuring longevity and durability.
2. Leak-Free Sealing: Precision threads paired with gaskets or sealants deliver dependable joint integrity, preventing leaks.
3. Easy Installation: Designed for hassle-free setup without welding, this feature significantly reduces labor and installation expenses.
4. Reusability: The threaded design facilitates effortless disassembly and maintenance, enhancing lifecycle efficiency.
5. Surface Finish: Choose from acid pickling, polishing, or sandblasting for improved aesthetics and resistance against contamination.


Applications
- Chemical/Petrochemical: Perfect for corrosive fluid and gas pipelines in demanding environments.
- Food/Pharmaceutical: Tailored for hygienic piping systems that align with GMP standards, ensuring safety and cleanliness.
- Water Treatment: Ideal for seawater desalination, water supply, and drainage systems, offering reliability and durability.
- Marine/Energy: Designed to withstand saltwater conditions in ships and offshore platforms, showcasing superior resilience.
- HVAC: Efficiently supports hot/cold water circulation systems, enhancing performance and reliability.


Technical Specifications
- Standards: Complies with ISO, ANSI/ASME B16.5, DIN, JIS, GB, and other international standards for quality assurance.
- Working Pressure: Engineered for performance under PN16 to PN40 pressure, ensuring dependable operation.
- Temperature Range: Operational between -20°C to +200°C, with 316L able to withstand even greater temperatures.



Installation & Maintenance Guidelines
1. Installation:
- Utilize thread sealant or PTFE tape to guarantee a leak-free connection, enhancing reliability.
- Exercise caution to prevent over-torquing, avoiding thread stripping or flange deformation for optimal performance.
2. Compatibility: Confirm that thread standards and pressure ratings are consistent with the components being connected for seamless integration.
3. Maintenance: Conduct regular inspections of seals and clean threads to mitigate corrosion buildup, ensuring long-term reliability.
