Socket Weld Flanges (SW)

Socket Welding Flanges (SW) are designed for high-pressure, small-bore piping. The pipe inserts into the socket for a fillet weld, ensuring superior strength and leak resistance compared to slip-on flanges. Ideal for hazardous systems up to Class 1500 (PN100), they are widely used in petrochemical, power, and hydraulic applications. Available in sizes NPS 1/2" to 6" (DN15-DN150).

Slip On Flanges (SO)

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.
