Slip on hubbed flange is a type of flange connection device, which is usually used to connect pipeline systems. It is characterized by a flat welding ring with a neck on one side of the flange, which is welded to the pipeline, providing a strong connection and good sealing.

BS3293 neck flat welding flange is a flange that meets the British Standard and is commonly used to connect high-pressure and high-temperature pipeline systems, providing strong connections and good sealing.

Features:

1. Welding neck: The prominent feature of flat welding flanges with necks is welding the neck. This neck is connected to the pipeline by welding, providing a sturdy connection.
2. Suitable for high pressure and high temperature: Due to its design and manufacturing standards, the neck flat welding flange is suitable for high pressure and high temperature pipeline systems, providing reliable performance.
3. Good sealing performance: Due to the characteristics of welding, slip on flanges usually have good sealing performance, which can effectively prevent leakage.
4. Widely applicable: Due to its strong connection and adaptability to various conditions, neck flat welding flanges are widely used in industries such as chemical, petroleum, and natural gas.

Advantages and disadvantages

Advantages
