Flanged flanged flange with neck is the flange that is connected to the tube with a circular tube. The butt welding flange is suitable for piping or high temperature, high pressure and low temperature piping for pressure or temperature fluctuating. It is also used for conveying expensive, inflammable and explosive tube. The welding flange is not easy to deform, sealed and widely used, the nominal pressure PN is around 16MPa.

The neck butt welding flange is also known as the high neck flange, which is suitable for situations where the pressure is larger, the temperature is higher and the pipe diameter is larger. The cover type has plane, surface, concave etc. Take butt welding neck flange refers to take neck and round pipe transition to the flange of pipe butt welding, butt welding line of flange is suitable for pressure or temperature fluctuations or high temperature, high pressure and low temperature pipes, also used to transport is expensive, inflammable, explosive medium on the pipeline. The flanged flange with neck is not easy to deform, sealed and widely used, nominal pressure PN is around 16MPa. Counterpart with flange and pipe butt welding neck flange is used for welding, its structure is reasonable, the strength and stiffness is bigger, can withstand high temperature and high pressure curve and temperature fluctuation, and repeated the sealing is reliable, the nominal pressure of 0.25 ~ 2.5 MPa with butt welding neck flange with concave and convex type sealing surface.

The neck butt welding flange is connected to the pipe end. The main parts that make the pipe connect to the pipe. The flanges have holes in it, and bolts can be worn, and the two flanges are tight, and the flanges are sealed with gaskets. Flange pipe fitting is a pipe with flange (flange or flange). It can be made from cast or threaded or welded.

The flanged flange with neck is not easy to deform, sealed and widely used, nominal pressure PN is around 16MPa. Counterpart with flange and pipe butt welding neck flange is used for welding, its structure is reasonable, the strength and stiffness is bigger, can withstand high temperature and high pressure curve and temperature fluctuation, and repeated the sealing is reliable, the nominal pressure of 0.25 ~ 2.5 MPa with butt welding neck flange with concave and convex type sealing surface.

Advantages of neck welding flange:

1. Connect the pipeline and maintain the sealing performance of the pipeline.

2. Facilitate the replacement of a certain pipeline.

3. Easy to disassemble the inspection pipeline.

4. Facilitate the closure of a certain section of the pipeline.
