Our 304/316 Stainless Steel Blind Flange (BL Flange) is a solid, disc-shaped sealing component engineered to permanently or temporarily block pipeline ends, isolate systems, or support pressure testing. Machined from premium stainless steel plates/forgings, it delivers exceptional corrosion resistance, structural integrity, and leak-proof performance—critical for low-to-high pressure industrial environments.
Key Features & Advantages
Dual-Grade Corrosion Resistance:304 offers reliable general corrosion resistance for standard industrial use; 316 (molybdenum-enhanced) excels in chloride, acidic, and marine environments, resisting pitting, crevice corrosion, and stress cracking.
Global Standard Compliance:Meets ANSI B16.5, ASTM A182, EN 1092-1, JIS B 2220, and DIN standards, ensuring interchangeability with global piping systems.
Precision Sealing:Available in Flat Face (FF), Raised Face (RF), and Ring Type Joint (RTJ) configurations. CNC-machined surfaces ensure tight gasket seating for zero leakage.
Wide Pressure/Size Range:Supports Class 150–2500 / PN6–PN100 pressures and DN15–DN1200 (1/2"–48") sizes; custom thicknesses (10–120mm) for unique project needs.
Easy Installation & Maintenance:Bolted design enables quick assembly/disassembly without cutting, ideal for system isolation, maintenance, and future expansion.
High Durability:Rugged construction withstands heavy loads, high temperatures, and repeated use, minimizing downtime and long-term maintenance costs.
Applications
Our 304/316 Blind Flanges are trusted across industries requiring reliable sealing and isolation:
Oil & Gas, Petrochemical, and Refinery Systems
Chemical Processing (acid, chloride, corrosive media)
