Types of Carbon Steel Weld Neck Flanges
This is the most common type of weld neck carbon steel flange. It has a tapered neck and a flared hub, which provides reinforcement and allows for easy alignment during welding. The standard weld neck flange is available in various sizes, pressure ratings, and facing types. The long weld neck flange has an extended neck length compared to the standard weld neck flange.
- Long Weld Neck Flange (LWNRF): The long weld neck flange has a longer neck length compared to the standard weld neck flange.
- Extra-Long Weld Neck Flange (XLWNRF): Extra-long weld neck flanges have an even longer neck length than the long weld neck flange.
- High Hub Weld Neck Flange (HHWNRF): High hub weld neck flanges have a taller hub height compared to standard weld neck flanges.
- Compact Weld Neck Flange: Compact weld neck flanges are designed with a shorter neck length, making them more compact and lighter than standard weld neck flanges.
- Swivel Ring Flange: Swivel ring flanges are a type of weld neck flange that allows rotation between the flange ring and the welding neck, providing flexibility in alignment during installation.
Features of Carbon Steel Weld Neck Flanges
- Weld neck carbon steel flanges provide a strong and secure connection between pipes or fittings through the welded neck, ensuring reliable performance in high-pressure and high-temperature applications.
- The design of weld neck flanges includes a tapered neck and a flared hub, providing reinforcement and additional strength to the flange connection.
- Weld neck carbon steel flanges offer excellent sealing capability when paired with a suitable gasket.
- Carbon Steel is known for its high strength and ability to withstand elevated pressures and temperatures, making weld neck carbon steel flanges suitable for demanding applications.
- The tapered neck design of weld neck flanges allows for easy alignment during the welding process, ensuring proper fitment and reducing the chance of misalignment.
