SERIES A FLANGE KEY FEATURES

markdown
1. **Dimensional Compliance**  
   - Outside Diameter (OD): 5-15% smaller than Series B  
   - Bolt Circle: Reduced diameter → Lower bolt loads  

2. **Installation Advantage**  
   - Weight Reduction: 42" flange ≈1,850 kg (vs. 2,400 kg for Series B)  
   - Compatible with ANSI B16.5 piping layouts  

3. **Gasket Specification**  
   - Spiral Wound: SS316/FG, OD per Series A dimensions  
   - Contact Face: 125-250 μm Ra finish
