1. Product Type
- The full name is “Welding Neck Flange,” designated as WN. It is one of the commonly used flange types, characterized by a short, tapered neck that is welded to the pipe.
2. Core Parameters
- Connection method: Butt welding (welding the pipe to the flange neck, with high-quality weld seams).
- Sealing surface types: Common types include raised face (RF), male-and-female face (MFM), and tongue-and-groove face (TG) (not labeled in the figure; RF is assumed by default).
- Pressure rating: Covers PN6 to PN420 (0.6 to 42 MPa), Class 150 to 2500 (American standard), suitable for both high- and low-pressure applications.
- Specification range: Nominal diameter DN10 to DN2000 (pipe diameter 1/2" to 48").
- Materials: Carbon steel (20#, Q345), stainless steel (304, 316L), alloy steel (15CrMo, 12Cr1MoV), etc., capable of meeting diverse medium and temperature requirements.
3. Product Features
- High strength: Necked structure + butt-welded connection, resistant to impact and high pressure, suitable for harsh operating conditions such as high temperature, high pressure, and flammable or explosive environments.
- Sealed and stable: The smooth transition between the neck and the pipe reduces fluid resistance and stress concentration, resulting in superior sealing reliability compared to flat-welded flanges.
- Application scenarios: Widely used in high-pressure pipeline systems in industries such as petrochemicals, power generation, metallurgy, and aerospace; often paired with equipment such as valves and pressure vessels.
