Flat welding ring loose sleeve steel flange

Overview:

The loose steel flange with flat welding ring is a rather special type of flange. The flat welding ring is a key component of this flange and is usually made of steel of the same material as the pipe. One end of the flat welding ring is connected to the end of the pipe by welding. The welding method is flat welding. The welding process is relatively simple and easy to operate, which can ensure the welding quality. The loose flange is placed on the flat welding ring, and it is not fixedly connected to the flat welding ring but can rotate relatively.
