Product Description
Stainless Steel Weld Neck Flange
Industrial-grade corrosion resistance and precision welding performance for demanding piping applications.
Product Overview
The stainless steel weld neck flange is a vital component in industrial piping systems, engineered for robust construction and structural integrity in challenging operating environments. Fabricated from premium stainless steel grades including 304 and 316L, these flanges deliver exceptional corrosion resistance and compatibility with high-pressure, high-temperature applications across multiple industrial sectors.
- Tapered hub design for smooth integration and uniform stress distribution
- Full penetration welding capability eliminates leak risks
- Stable performance in extreme temperature variations
- Available in sizes from DN10 to DN600 with pressure ratings from 150-2500 class
- Compliant with ANSI/ASME B16.5, DIN 2633, and EN 1092-1 standards
Material Specifications
Our weld neck flanges are available in two primary stainless steel grades to suit various application requirements:
- 304 Stainless Steel: Ideal for general-purpose applications including food processing, water treatment, and light chemical plants
- 316L Stainless Steel: Optimized for marine environments, chloride-rich settings, and heavy-duty chemical processing with enhanced pitting and crevice corrosion resistance
