Flanges
Slip-On (SO) Flanges
Slip-On flanges slide over the pipe end and are fillet-welded on both sides, providing easy alignment and installation. While not as strong as Weld Neck flanges, they are cost-effective for moderate-pressure applications up to Class 600. Shree Raj Steels supplies SO flanges in all standard sizes and materials with options for raised face, flat face, and ring-type joint configurations.
