Butt welding flange has certain technical requirements and technical parameters in production and application, and it should be produced and processed according to certain methods and methods: the butt weld of ring should be subject to post weld heat treatment, and 100% ray or ultrasonic testing, and the ray testing meets the class II requirements of JB4730, and the ultrasonic testing meets the class I requirements of JB4730.
Butt welding flange is raw material, steel plate should be ultrasonic flaw detection, no lamination defect, to ensure good quality and functional problems, in accordance with certain quality requirements of production and inspection, to ensure that the production and use of steel plate without quality problems.

Butt welding flange can greatly save space, reduce weight, and it can ensure that the joint will not appear leakage phenomenon, has a very good sealing function. The diameter of the seal is reduced, which will reduce the section of the sealing surface. The size and number of bolts will be reduced accordingly, so it will eventually present a small and light butt welding flange. Therefore, this is an excellent flange, which reduces the burden of quality and space, and has an important effect on industry.
