Flat welding flange in the production and use of certain technical requirements and technical parameters, according to a certain way and method of production and processing:

The flat welding flange shall be cut into strips along the rolling direction of the steel, and shall be welded into a circular ring by bending, and the surface of the steel shall form a cylindrical surface of the ring.When producing flat welded flanges, steel plate should not be machined directly into neck flanges, and certain technology should be used to make and process them.
 

The steel plates for the production of flat welded flanges shall be inspected by ultrasonic inspection without layering defects to ensure good quality and performance problems. Production and inspection shall be conducted according to certain quality requirements to ensure that the steel plates for production and use have no quality problems.
