Briefing

Slip-On Flanges (SO) are designed to slip over pipe ends for internal and external fillet welding. Their low-hub structure offers better rigidity than plate flanges at a lower cost. Ideal for low-to-medium pressure systems (PN≤2.5MPa), they are widely used in chemical, oil, and municipal engineering. Sizes range from 1/2" to 60", with custom options available.
