Product Description
Stainless Steel Blind Flange - Wear-Resistant, Erosion-Proof for Heavy-Duty Industrial Piping
Product Overview
Our Stainless Steel Blind Flange is a rugged sealing component engineered specifically for wear and erosion-prone heavy-duty industrial environments. Constructed from hardened 316L stainless steel with surface hardening treatment (HRC ≥ 45), it withstands abrasive media, high-velocity fluid impact, and particle erosion.
Key Features & Benefits
- Exceptional wear resistance with hardened surface layer providing 3x better abrasion resistance than standard flanges
- Forged body ensures high impact strength against particle collision
- Optimized sealing face design prevents media penetration and erosion around bolt holes
- Maintains leak-tight performance in long-term harsh service conditions
- Reduces replacement frequency and maintenance costs
- Ideal for mining slurry systems, power plant ash handling, cement processing, and oil & gas sand production lines
Technical Specifications
Compliant with API 605, ASME B16.5, and EN 1092-1 standards. Our blind flanges cover sizes from 1/2" to 60" and pressure classes up to Class 900. Each unit undergoes rigorous hardness testing, abrasion resistance verification, and non-destructive inspection to ensure suitability for heavy-duty applications.
