WN Neck Flanges are essential for industrial applications requiring secure, durable pipe connections across pressure ratings from PN2.5 to PN160. Their forged and machined construction ensures exceptional strength and reliability in demanding conditions.
Common applications include:
The advanced surface treatment (heat treatment, pickling, and passivation) significantly enhances corrosion resistance, making these flanges suitable for harsh environments with corrosive substances.
Our Welding Neck Flanges offer exceptional corrosion resistance with material-specific performance. Available in a comprehensive range including:
All flanges feature ANSI B16.25 bevel ends for proper fit and weld quality, with weights varying by size and material to meet specific project requirements.
We provide comprehensive technical support and services for optimal flange performance:
For technical support, please have flange specifications (size, pressure rating, material, standards) ready. Proper welding procedures and alignment are critical for installation success.
