The Welding Neck Flange (WN Flange) is a critical component designed for secure, leak-proof connections in various piping systems. Manufactured in compliance with EN 1092-1 standards, these flanges deliver reliable performance under high pressure and temperature conditions. Available with Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) facetypes, they offer superior sealing capabilities and application flexibility.
Featuring a bevel end design per ANSI B16.25 standards, these flanges facilitate smooth welding operations, ensuring proper alignment and reducing weld defects. The welding connection method creates a permanent, high-strength bond ideal for demanding pressure environments ranging from 150# to 2500#.

Welding Neck Flanges are essential components in industrial applications requiring robust, reliable connections. Their design makes them ideal for high-pressure environments in oil and gas, petrochemical, power generation, and chemical processing industries.
These flanges are manufactured from premium materials including X1NiCrMoCu25-20-5 1.4539, A182 F904L, 13CrMo4-5, and 10CrMo9-10, ensuring excellent corrosion resistance and mechanical strength. The tapered hub design minimizes stress concentration, making them suitable for pipelines subject to vibration and dynamic forces.
Common applications include high-pressure pipelines, refineries, offshore platforms, chemical plants, and steam/gas/water pipelines where maintaining system integrity under fluctuating temperatures and pressures is critical.
We offer comprehensive customization services to meet specific project requirements. Our Welding Neck Flanges are available in various types including WN flanges with face options of Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) to suit different sealing needs.
Customization includes pressure ratings from 150# to 2500#, long weld neck end types, and specialized materials such as F22 flange EN 1092-1, EN 1092-1 Weld Neck Flange 1.4541 (321) Stainless PN16 with Raised Face, and 13CrMo4-5 flange options for enhanced mechanical properties and thermal stability.
Our technical support team provides comprehensive assistance with product selection, installation guidance, and troubleshooting. We supply detailed documentation including dimensional drawings, material specifications, and compliance certifications.
Services include custom flange fabrication, timely delivery, and post-sale support throughout the product lifecycle. We recommend following industry best practices for welding and installation, including proper alignment, welding technique, and inspection to ensure strong, safe flange connections.
Additional resources such as installation videos, FAQs, and application case studies are available through our online support portal to assist with successful implementation of our Welding Neck Flange products.
