(Summary description)The butt welding flange can greatly save space and reduce the weight, and it can also ensure that the joints will not leak out. It has very good sealing performance. The size of the butt welding flange is reduced due to the sealing The diameter of the piece stops reducing, which will reduce the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by a sealing ring, in order to ensure the matching of the sealing surface to the sealing surface.

Information

The butt welding flange can greatly save space and reduce the weight, and it can also ensure that the joints will not leak out. It has very good sealing performance. The size of the butt welding flange is reduced due to the sealing The diameter of the piece stops reducing, which will reduce the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by a sealing ring, in order to ensure the matching of the sealing surface to the sealing surface.
The main functions of butt welding flanges are divided into the following categories:
   1. The pipeline is defective, which is easy to disassemble and inspect.
  2. If there is a problem with a certain section of pipeline, it is convenient to change a certain section of pipeline;
  3, connect the pipeline and make the pipeline maintain good sealing performance;
Butt welding flanges have certain technical requirements and technical parameters in the production and application, and they are produced and processed according to certain methods and methods:
  1. The steel plates of the consumer butt welded flanges should be ultrasonically inspected, without delamination defects, to ensure good quality and performance problems, and to request production and inspection in accordance with a certain quality to ensure that the steel plates consumed and used have no quality problems;
  2, the butt weld of the ring should stop the heat treatment after welding, and be 100% radiographic or ultrasonic inspection, and the radiographic inspection meets the level II requirements of JB4730, and the ultrasonic inspection meets the level I requirements of JB4730. Butt-welding flanges adopt certain welding specifications and technical production and processing, which conform to the corresponding national consumption specifications and requirements.
  3. It should be cut into strips along the rolling direction of the steel, then be bent and butt welded into an annular shape, and the outer surface of the steel should be formed into the cylindrical surface of the ring. In the production of flanges, the steel plate shall not be directly machined into flanges with necks, and certain processes shall be used for manufacturing and processing.
