Slip on Flanges

The slip-on flange (SO flange) features an oversized bore that slides directly over the pipe OD and is secured with dual fillet welds – one on each face – for reliable, leak-resistant joints. Available in carbon, alloy, and stainless steel grades, it suits low-to-medium pressure fluid systems across oil & gas, water treatment, and chemical processing. Cost-effective forged construction, multi-face options (RF/RTJ), and full ASME B16.5 compliance make it a preferred export-grade piping component.
