The main function and processing method of welding flange
Welding flange can greatly save space, reduce weight, and it can also ensure that the joint part will not show leakage phenomenon, has very good sealing performance. welding flange size is reduced, because the diameter of the seal stops to reduce, which will reduce the section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring, in order to ensure that the sealing face matches the sealing surface.
The main function of welding flange
The main role of welding flange is divided into the following categories:
1.The pipeline is faulty, easy to disassemble and detect.
2. If a certain section of pipeline presents problems, it is convenient to change a certain section of pipeline;
3. Connect the pipeline and make the pipeline adhere to good sealing performance;
Machining method of welding flange:
1.Welding flange has certain technical requirements and technical parameters in the consumption and application, according to certain ways and methods of consumption and processing:
2. Consumption of steel plate welding flange should be ultrasonic inspection, no layered defects, to ensure good quality and performance problems, according to a certain quality requirements of consumption and inspection, to ensure the consumption and use of steel plate without quality problems;
3. The butt weld of the ring shall stop the thermal treatment after welding, and be subjected to 100% X-ray or ultrasonic inspection, and the X-ray inspection conforms to the II requirement of JB4730, and the ultrasonic inspection conforms to the I requirement of JB4730. The welding flange adopts certain welding specifications and technical consumption processing, which conforms to the corresponding national consumption specifications and requirements.
4. It should be cut into strips along the direction of steel rolling, welded into a circular ring by bending, and the outer surface of the steel to form the cylinder of the ring. The steel plate shall not be machined directly into the neck flange when consuming the Ha-flange, and a certain process shall be adopted for manufacturing and processing.
