Stainless Steel Slip On Flange ASME B16.5 PN16 PN25 for Low Pressure Pipeline, Heating System, Water and Gas Supply

Slip-On Flanges (SO Flanges) are widely used in low and medium-pressure piping systems due to their simple installation, easy alignment, and cost-effective performance. The pipe can be inserted directly into the flange bore and welded from both sides, which significantly reduces alignment errors and improves installation efficiency. SO flanges are commonly applied in water supply networks, HVAC systems, petrochemical plants, natural gas pipelines, shipbuilding, and power station auxiliary lines. They help solve engineering challenges such as limited installation space, demanding construction schedules, and pipeline misalignment.

Our SO flanges are manufactured from high-quality carbon steel or stainless steel and fully comply with ASME, EN, DIN, and GOST standards. They feature excellent weldability, reliable sealing performance, stable pressure resistance, and high machining accuracy. Various pressure ratings, sealing faces, surface treatments, and customized non-standard sizes are available to meet different engineering requirements.

With a simple structure and strong adaptability, Slip-On Flanges are one of the most commonly used flange types in the Russian industrial market, offering reliable performance for pressure systems, fluid transport pipelines, and equipment connections.
