SO RF Slip On Flange Type

SO RF Slip On Flange Type Product Overview The SO RF Slip On Flange is an economical yet reliable Standard pipeline flanges designed for low-to-medium pressure industrial piping systems, serving as a cost-effective industrial pipeline connection flanges that slips over the pipe end and is welded on the outer surface (single weld). As a widely used member of multi-standard pipe flanges family, this slip-on flange balances performance and cost, making it the preferred choice for non-critical applications such as water supply, HVAC, and general industrial piping. Unlike welding neck flanges (WN) with a tapered hub, the SO RF Slip On Flange has a flat hub that slips directly over the pipe, reducing machining complexity and cost while maintaining adequate structural integrity for Class 150-600 (PN10-PN40) applications. As a standardized Standard pipeline flanges, it complies with ASME B16.5, EN 1092-1, and GB/T 9119 standards, ensuring compatibility with global piping systems in multi-stan…
