Large Diameter 316L Stainless Steel Weld Neck Flange (WN Flange) Successfully Delivered for High-Pressure Applications
We are pleased to announce the successful production and delivery of a batch of large diameter 316L stainless steel weld neck flanges (WN flanges), manufactured for demanding industrial piping systems.
This project highlights our advanced capabilities in precision CNC machining, large-scale flange manufacturing, and high-performance fluid system components.
Product Overview ------ High-Precision Large Diameter WN Flange
The delivered product is a large diameter industrial flange designed for high-pressure and high-temperature pipeline systems.
From the visual and structural perspective, the flange demonstrates outstanding machining quality:
- Ring-shaped integral structure ensuring excellent dimensional stability
- Evenly distributed bolt holes on the outer circumference for secure and uniform fastening
- Precision-machined stepped sealing face designed for gasket placement and leak-proof performance
- Weld neck (WN) design with smooth transition radius, reducing stress concentration and improving mechanical strength
Key Features of 316L Stainless Steel Weld Neck Flange
1. Material & Surface Quality
- Manufactured from 316L stainless steel, offering superior corrosion resistance in harsh environments
- Smooth silver metallic finish with excellent surface consistency
- Critical surfaces processed by high-precision CNC turning
- Clean edges and burr-free finishing, meeting high industrial standards
2. Structural Design & Performance
- High-precision bolt holes for accurate assembly and load distribution
- Designed for large diameter pipelines and high flow systems
- Weld neck structure enhances strength under pressure and temperature fluctuations
- Stepped sealing face ensures reliable sealing performance with gaskets
Applications of Large Diameter WN Flanges
This type of industrial weld neck flange is widely used in critical pipeline systems requiring high strength and sealing reliability:
- Oil & Gas pipeline systems
- Petrochemical and chemical processing plants
- Power generation and energy industries
- Metallurgy and heavy industrial equipment
- Municipal infrastructure and large-scale piping systems
Core Functions:
- High-strength pipeline connection
- Valve and equipment interface connection
- Pipeline end closure (with blind flange)
- Leak-proof sealing for fluid systems
Industry Knowledge – Flange Selection Standards
In industrial engineering, flanges are typically specified based on:
- Pressure Rating (Class / PN)
- Nominal Diameter (DN)
- Sealing Face Type (RF, RTJ, etc.)
Selecting the correct flange type is essential for ensuring system safety, durability, and sealing performance.
