EN1092-1 standard 304 PN10 FF Slip-On Flange is food-grade hygienic socket flange manufactured from virgin SUS304 stainless steel, designed for drinking water, beverage, dairy and light corrosive low-pressure pipeline systems. Different from RF type slip-on flange, it adopts FF full-face full-plane contact structure, which makes the whole flange surface fit gaskets completely, avoiding gasket extrusion displacement under low-pressure steady operation, ideal for sanitary pipeline zero-residue connection demand.
The inner socket bore is precision polished to eliminate inner burrs, preventing material residue and bacterial growth during fluid circulation. Overall 180-grit mirror finishing complies with FDA food contact standard, safe for edible liquid and potable water delivery. PN10 low pressure grade bears 1.0MPa working pressure, suitable for long-cycle continuous pipeline running. Integral forged structure improves socket roundness, ensuring seamless pipe slipping and concentric positioning, greatly lowering assembly difficulty for clean workshop modular piping installation.
Each finished flange passes salt spray anti-corrosion test and dimensional tolerance test. Inner and outer double fillet welding structure enhances connection stability, allows repeated disassembly and assembly without socket deformation. Size DN20-DN500 EU standard size in stock. Custom service includes surface polishing degree, laser logo marking, customized socket bore size. Widely applied in drinking water plant, beverage production line, pharmaceutical clean workshop, non-chloride light chemical pipeline. Export fumigated wooden package with sealing protective film, 18-month stainless steel warranty, free FDA & MTC material certificate.
