Knowledge Expansion
Flat welding and butt welding refer to the welding methods used when connecting flanges and pipes. When welding flat welding flanges, only one side is required for welding, and no connection between the inner port of the pipe and the flange is required. The welding and installation of welding flanges requires double-sided welding of the flange. Therefore, flat welding flanges are generally used for medium and low pressure pipelines, and welding flanges are used for the connection of medium and high pressure pipelines.
