Forged SS316 Threaded Flange JIS20K RF Surface with ISO Certification

Stainless Steel Threaded Flange

Our Stainless Steel Threaded Flanges represent precision engineering at its finest, designed to seamlessly connect pipelines, valves, or equipment through threaded joints. Crafted from premium-grade stainless steel such as 304, 316, or 316L, these flanges exhibit exceptional strength, stellar corrosion resistance, and impressive high-temperature endurance. By merging the robustness of flanges with the practicality of threaded connections, they stand out as the perfect choice for low-to-medium pressure systems. Ideal for scenarios where disassembly is frequent or where space is at a premium.

- HVAC: Efficient for hot and cold water circulation systems, ensuring seamless temperature regulation.


Technical Specifications
- Standards: Conforming to ISO, ANSI/ASME B16.5, DIN, JIS, GB, and other international standards for quality assurance.
- Working Pressure: Robust performance from PN16 to PN40, ensuring resilience under pressure.
- Temperature Range: Operates in temperatures ranging from -20°C to +200°C, with 316L capable of withstanding even higher temperatures.



Installation & Maintenance Guidelines
1. Installation:
- For optimal results, apply thread sealant or PTFE tape to prevent any potential leakage.
- Take care to avoid over-torquing to ensure the integrity of the threads and prevent flange deformation.
2. Compatibility: Check that thread standards and pressure ratings align with connected components for seamless integration.
3. Maintenance: Conduct regular inspections of seals and keep threads clean to avert corrosion buildup and ensure long-lasting performance.
