FLAT PLATE WELDING FLANGES
Reliable Sealing Solutions for Industrial Piping Systems

Product Features & Applications

1. Versatile Welding Compatibility:
   • Designed for flat-face welding to pipes, ideal for low-to-medium pressure systems (up to 42.0MPa).
   • Simplified installation: Single-sided welding reduces labor costs and construction time.
2. Wide Industrial Use:
   • Chemical processing, oil/gas pipelines, HVAC, and water treatment applications.
   • Needle-type valve series compatibility: Precision-engineered for high-temperature, abrasive, or corrosive fluids.
3. Material Durability:
   • Austenitic stainless steel: 304/304L, 321, 316/316L (resists pitting/crevice corrosion).
   • Carbon steel: A105, Q235 (cost-effective for non-critical air/water services).
   • High-temperature alloys: Custom options for needle valves (e.g., Inconel, Hastelloy).
