Quantity
As a dedicated Slip On Flange China Manufacturer, we supply high-quality SO flanges in sizes from ½ to 24 inches, fully compliant with ASME B16.5. These forged carbon steel flanges cover pressure classes 150 through 2500 LB, with face options of flat face (FF) and raised face (RF). Surface black treatment enhances corrosion resistance and durability, making them suitable for water systems, oil and gas pipelines, and general industrial services.
Design Principle
The flat sealing face creates uniform gasket contact pressure, avoiding stress concentration common in recessed or tongue‑and‑groove designs. When used with full‑face gaskets (e.g., rubber or non‑metallic composites), the seal remains reliable in low‑pressure and non‑critical applications. This straightforward geometry also simplifies alignment during installation, reducing assembly time and gasket damage risks.

Performance Data
Per ASTM and ASME standards, our Slip On Flange excels below 150 psi. Test results show:
- Leakage rate ≤ 0.01 cc/min at 100 psi with rubber gaskets.
- FEA‑verified contact pressure deviation < 5%, ensuring even load distribution.
- Stable sealing from ‑20°C to 120°C, with negligible leakage variation.

Optimization Recommendations
- Keep flange and gasket surfaces clean before assembly.
- Periodically inspect gaskets; replace aged or damaged ones promptly.
- For temperatures above 120°C or pressures nearing the class limit, upgrade to PTFE or graphite gaskets for enhanced reliability.
