High neck flange
Neck butt welding flange refers to the flange with neck and round pipe transition and butt welding connection with the pipe. Neck butt welding flange is suitable for pipelines with large pressure or temperature fluctuations or high temperature, high pressure and low temperature. Pipes are also used to transport expensive, flammable and explosive media. The butt-welded flange with neck is not easy to deform, has good sealing, and is widely used. The nominal pressure PN is about 16MPa.

advantage:
1. Connect the pipeline and maintain the sealing performance of the pipeline.
2. Facilitate the replacement of a certain section of pipeline.
3. It is easy to disassemble and check the pipeline condition.
4. Facilitate the closure of a certain section of pipeline.
