304 stainless steel flange/round steel forging/GB flat welding/butt welding /HG5010/ 16kg pressure

304 stainless steel flange/round steel forging/GB flat welding/butt welding /HG5010/ 16kg pressure

Main functions of flange:
1, pipe failure, easy to disassemble detection;
2. Connect the pipeline and keep the pipeline with good sealing performance;
3. If a certain section of pipeline has problems, it is easy to replace a certain section of pipeline.
Flat welding flange in production and use has certain technical requirements and technical parameters, according to a certain way and method of production and processing:
1. The butt weld of the ring shall be subjected to post-welding heat treatment and 100% ray or ultrasonic inspection, and the ray inspection shall meet the grade II requirements of JB4730, and the ultrasonic inspection shall meet the grade I requirements of JB4730.Butt welding flange adopts certain welding standards and technology production and processing, in line with the corresponding production standards and requirements of ***.
2, the production of flat welding flange steel plate should be ultrasonic inspection, no delamination defects, to ensure good quality and performance problems, in accordance with certain quality requirements of production and inspection, to ensure that the production and use of steel plate no quality problems;
3, should be along the steel rolling direction cut into strips, bending welding into a circular ring, and make the surface of the steel ring cylindrical.The steel plate shall not be directly machined into a neck flange in the production of the joint flange, and a certain technology shall be used for production and processing.
