LOOSE PLATE WELDING FLANGE (SLIP-ON FLANGE)
Flexible Sealing Solutions for Easy Maintenance & Installation
Product Features & Applications
- Modular Design Advantage:
- Detachable hub-and-plate structure allows quick installation/removal for maintenance or pipe modifications.
- Ideal for low-to-medium pressure systems (1.6-6.4MPa) in chemical, petroleum, HVAC, and water treatment industries.
- Material Versatility:
- Carbon Steel: Q235 (general-purpose), 16Mn (improved strength), 15CrMo (high-temp creep resistance).
- Stainless Steel: 304/304L, 316/316L (corrosion resistance); ICR18N9Ti (titanium-stabilized for intergranular stress relief).
- Cost-Efficient Construction:
- Forged or cast hub + welded plate reduces material costs vs. solid flanges.
- Lightweight design simplifies handling for large diameters (up to DN2000).
