Slip-On Flange (SOP) is a widely used piping connection component designed for low to medium pressure systems. It is available in core materials including carbon steel and stainless steel, making it adaptable to diverse industrial, commercial, and plumbing applications.

This flange features a simple slip-on design: it slides directly over the end of a pipe, then is secured by fillet welding at both the inner and outer edges of the flange. This installation method is quicker and more cost-effective than welding neck flanges, making it a popular choice for projects prioritizing efficiency.

The flat sealing surface (raised face in standard configurations), when paired with a gasket, creates a reliable, leak-proof seal. Pre-drilled bolt holes ensure precise alignment with mating flanges, simplifying assembly. Carbon steel versions offer high strength for general-purpose use, while stainless steel variants provide superior corrosion resistance for chemical, food processing, and marine environments.

Alongside the standard SOP type, the product range also includes Slip-On Hub (SOH) flanges (with an extended hub for enhanced stability) and Blind flanges (used to seal the end of a piping system). This versatility makes slip-on flanges suitable for water supply, HVAC, oil and gas, and process piping systems.
