Brief description

Weld neck flange is a neck butt welding flange, the full name is a neck butt welding steel pipe flange, a neck butt welding flange refers to a flange with a tapered neck and butt welding with the cylinder or pipe. It is an integral flange. Due to the transition structure of the tapered neck and the butt welding connection, the strength and rigidity of the flange are strengthened, and the sealing performance is better than that of the flat welding flange. The disadvantage is that it needs to be manufactured with forgings, which consumes a lot of materials and costs a lot. It is suitable for occasions with high pressure, high temperature or high sealing requirements.

Butt welding flange with neck refers to a flange with a neck and a round pipe transition and connected to the pipe butt welding. Butt welding flange is suitable for pipelines with large fluctuations in pressure or temperature or high temperature, high pressure and low temperature pipelines. It is also used in pipelines for conveying expensive, flammable and explosive media. The butt welding flange with neck is not easy to deform, has good sealing and is widely used, and the nominal pressure PN is about 16MPa. Butt welding flanges are suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high temperature, high pressure and low temperature, and are also used for pipelines that transport expensive, flammable and explosive media. Butt welding flange is not easy to deform, well sealed, widely used, and the nominal pressure PN is about 16MPa. Advantages: 1. Connect the pipeline and maintain the sealing performance of the pipeline. 2. It is convenient for the replacement of a certain pipeline. 3. It is easy to disassemble and check the pipeline condition. 4 to facilitate the closure of a certain section of the pipeline.
