Corrosion-resistant, precision-engineered for industrial piping systems with exceptional durability and reliable performance in harsh operating conditions.
Product Overview
Engineered with high-grade 304 and 316L stainless steel, this weld neck flange is designed to resist corrosion, pressure, and temperature fluctuations. The integrated tapered hub creates seamless connections and distributes stress evenly across joints, enabling full penetration welding for leak-proof seals essential for handling corrosive fluids, toxic gases, and abrasive materials.
Key Features
- Exceptional corrosion resistance for harsh environments
- Even stress distribution through tapered hub design
- Full penetration welding capability for leak-proof seals
- Available in 304 and 316L stainless steel variants
- Comprehensive size range and pressure classes (150 to 2500)
- Compliant with ANSI/ASME B16.5, DIN 2633, and EN 1092-1 standards
- Stringent quality control for material composition and dimensional accuracy
Applications
Ideal for oil and gas exploration, petrochemical refining, power generation, pharmaceutical manufacturing, food processing, water treatment, marine facilities, and chemical plants. Suitable for both new construction projects and system upgrades.
