Our 304/316 Stainless Steel Slip On Flange (SO Flange) is a widely used, cost-effective connecting component designed for seamless pipeline joints. Characterized by its flat, ring-shaped design with a hub, it slips over the end of a pipe and is secured with fillet welds on both the inner and outer sides, ensuring strong, leak-proof connections. Crafted from premium 304 and 316 stainless steel, this flange offers exceptional corrosion resistance, structural reliability, and ease of installation, making it a preferred choice for low-to-medium pressure industrial piping systems worldwide.
Compared to other flange types, the slip on flange features a simple structure, lower manufacturing cost, and convenient installation—no precise pipe end alignment is required, reducing labor and time during assembly. It is widely applied in various industrial scenarios where reliable performance and cost-efficiency are key, balancing functionality and economy for large-scale projects and standard pipeline connections.
Key Features & Advantages
Dual-Grade Corrosion Resistance:304 stainless steel provides excellent resistance to general corrosion, suitable for standard industrial environments with water, air, and non-corrosive media. 316 stainless steel, reinforced with molybdenum, offers superior protection against chlorides, acids, and marine conditions, effectively preventing pitting, crevice corrosion, and stress cracking.
Global Standard Compliance:Fully adheres to international standards including ASTM A182, ANSI B16.5, EN 1092-1, JIS B 2220, and DIN, ensuring interchangeability with global piping systems and equipment, making it ideal for domestic and overseas projects.
Easy Installation & Cost-Effective:The slip-on design allows the flange to slide directly over the pipe, eliminating the need for precise pipe end machining or alignment. Fillet welding is simple and efficient, reducing installation time and labor costs. Its cost-effective manufacturing process makes it suitable for large-volume projects.
Precision Sealing & Stability:CNC-machined sealing faces (Flat Face/FF, Raised Face/RF) ensure tight gasket seating, preventing leakage even in low-to-medium pressure applications. The hub design enhances structural stability, distributing pressure evenly across the connection for long-term reliability.
Wide Pressure & Size Range:Suitable for low-to-medium pressure applications (Class 150-Class 2500 / PN6-PN100), with a size range from DN15 to DN3000 (1/2"-120"), covering most industrial piping needs. Custom sizes, thicknesses, and hub designs are available on request.
High Durability & Longevity:Rugged stainless steel construction withstands high temperatures, heavy loads, and repeated use, minimizing maintenance needs and downtime. The surface is treated with anti-rust coating or polishing to further enhance corrosion resistance and extend service life.
Applications
Our 304/316 Stainless Steel Threaded Flanges are widely used in industries that require convenient installation and reliable sealing, including:
Petrochemical, Oil & Gas, and Refinery Systems
Chemical Processing (non-highly corrosive media)
Water Supply, Wastewater Treatment, and Plumbing Systems
