Our 304/316 Stainless Steel Threaded Flange (TH Flange) is a high-performance connecting component designed for quick, detachable pipeline joints. Featuring precision internal or external threads, it enables easy assembly and disassembly without welding, making it ideal for low-to-medium pressure industrial piping systems. Crafted from premium 304 and 316 stainless steel, this flange delivers exceptional corrosion resistance, structural stability, and long service life, perfectly adapting to various harsh industrial environments.
Unlike welded flanges, our threaded flange adopts a screw connection design, which not only simplifies installation and maintenance but also reduces the risk of pipeline damage caused by welding. It is widely used in scenarios where frequent disassembly is required, such as equipment maintenance, pipeline inspection, and temporary pipeline connections, while ensuring leak-proof performance and reliable operation.
Key Features & Advantages
- Dual-Grade Corrosion Resistance:304 stainless steel provides excellent general corrosion resistance for standard industrial applications, suitable for water, air, and non-corrosive media. 316 stainless steel, enhanced with molybdenum, offers superior resistance to chlorides, acids, and marine environments, effectively preventing pitting, crevice corrosion, and stress cracking.
- Global Standard Compliance:Fully meets international standards including ASTM A182, ANSI B16.5, EN 1092-1, JIS B 2220, and DIN, ensuring interchangeability with global piping systems and equipment, suitable for overseas projects.
- Precision Thread & Sealing:Adopts advanced CNC threading technology, ensuring precise thread pitch and smooth surface, which fits tightly with threaded pipes to avoid leakage. Available in NPT, BSPP, BSPT thread standards; sealing faces (FF, RF) are CNC-machined for tight gasket seating and zero leakage.
- Easy Installation & Maintenance:No welding required, just screw the flange to the threaded pipe, significantly reducing installation time and labor costs. The detachable design allows quick disassembly for pipeline maintenance, inspection, and replacement, improving work efficiency.
- Wide Pressure & Size Range:Suitable for low-to-medium pressure applications (Class 150-Class 600 / PN6-PN40), with size range from DN15 to DN200 (1/2"-8"), covering most industrial piping needs. Custom sizes and thread types are available on request.
- High Durability:Rugged stainless steel construction withstands high temperatures, heavy loads, and repeated use, minimizing downtime and long-term maintenance costs. The surface is treated with anti-rust coating or polishing to further enhance corrosion resistance and service life.
