Product Description

Stainless Steel Threaded Flange

 

Product Description

Stainless steel threaded flanges are expertly crafted pipe fittings, engineered to connect pipelines, valves, or equipment using threaded joints. Made from premium-grade stainless steel (e.g., 304, 316, 316L), these flanges offer remarkable strength, exceptional corrosion resistance, and superior high-temperature tolerance. The design fuses the robust stability of traditional flanges with the practical convenience of threaded connections, rendering them perfect for low-to-medium pressure systems. They are especially suitable for applications that demand frequent disassembly or are constrained by limited space.


Structure
1. Material: Crafted from austenitic stainless steel (304/316/316L, etc.), with options for custom grades to cater to diverse needs.
2. Connection Type: Available in internal or external threads, meeting standards such as NPT, BSPP, or G-thread for precise compatibility.
3. Face Type: Choose from flat face (FF), raised face (RF), or bespoke configurations to suit specific applications.
4. Size Range: Offering a nominal diameter (DN) from DN15 to DN4000, with pressure ratings extending from PN10 to PN40 (or Class 150-300) to meet various demands.


Key Features
1. Corrosion Resistance: Expertly designed to withstand acidic, alkaline, saline, humid, or high-temperature conditions, ensuring longevity and reliability.
2. Leak-Free Sealing: Precision threads paired with gaskets or sealants deliver dependable joint integrity, preventing leaks.
3. Easy Installation: No welding needed, significantly lowering labor and installation costs, and enhancing efficiency.
4. Reusability: The threaded design allows for hassle-free disassembly and maintenance, promoting sustainability.
5. Surface Finish: Options include acid pickling, polishing, or sandblasting for improved aesthetics and resistance to contamination.


Applications
- Chemical/Petrochemical: Perfect for corrosive fluid and gas pipelines, ensuring safety and durability.
- Food/Pharmaceutical: Ideal for hygienic piping systems compliant with GMP standards, maintaining purity and quality.
- Water Treatment: Efficiently used in seawater desalination, water supply, and drainage systems.
- Marine/Energy: Engineered for saltwater-resistant piping in ships and offshore platforms, ensuring longevity.
- HVAC: Essential for hot/cold water circulation systems, providing reliable performance.


Technical Specifications
- Standards: Manufactured according to ISO, ANSI/ASME B16.5, DIN, JIS, GB, and other international standards.
- Working Pressure: Designed to handle pressures from PN16 to PN40, ensuring adaptability to various applications.
- Temperature Range: Suitable for temperatures from -20°C to +200°C, with 316L capable of withstanding even higher temperatures.



Installation & Maintenance Guidelines
1. Installation:
- Apply thread sealant or PTFE tape strategically to ensure a foolproof, leak-free seal.
- Avoid over-torquing to protect against thread stripping or flange deformation, preserving integrity.
2. Compatibility: Meticulously verify that thread standards and pressure ratings are compatible with connected components.
3. Maintenance: Conduct regular inspections of seals and clean threads diligently to avert corrosion buildup.
