Weld Neck Flanges: Types and Applications
We specialize in a variety of weld neck flange types, including:
- Weld Neck Raised Face (WNRF) Flanges: These flanges feature a raised face that enhances gasket performance and ensures a secure seal in high-pressure applications.
- Weld Neck Flat Face (WNFF) Flanges: Designed for use in flat-faced piping systems, these flanges provide reliable connections in moderate-pressure environments.
- Long Weld Neck Flanges (LWNRF): These flanges have an extended neck that makes them suitable for high-pressure systems where stress distribution is critical.
- Galvanized Weld Neck Flanges: Our galvanized flanges are coated with zinc to provide additional protection against corrosion, making them ideal for use in outdoor and marine environments.
Dimensional Standards and Pressure Ratings
Our weld neck flanges conform to a wide range of dimensional standards, including ANSI/ASME B16.5, B16.47 Series A & B, B16.48, JIS B2220, BS 4504, BS 10, BS1560-3.1, EN-1092, DIN, AS, GOST, MSS SP-44, ISO 70051, API7S-15, API7S-43, API605, and AWWA.

Connection Types
We offer weld neck flanges with various connection types to suit different piping systems:
- Ring Joint Flange (RTJ): Provides a metal-to-metal seal, ideal for high-pressure and high-temperature applications.
- Flat Face Flange (FF): Suitable for use with flat-faced piping systems, ensuring even gasket compression.
- Raised Face Flange (RF): Commonly used in industrial applications for its ability to concentrate more pressure on a smaller gasket area.
- Male and Female Flange (M & F): Ensures a strong, leak-proof connection between pipes.
- Lap Joint Flange: Allows for easy alignment and assembly in piping systems with frequent disassembly.
- Tongue-and-Groove Flange (T & G): Provides a tight seal, often used in hazardous fluid handling systems.
