Steel Pipe Welding Neck Flange
Flat welding and butt welding are the welding methods for connecting flanges and pipes. When welding flat welding flanges, only one side welding is required, and there is no need to weld the inner opening of the pipe and flange connection. The welding installation of butt welding flanges requires double flange welding. Face welding. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for the connection of medium and high pressure pipelines. Butt welding flanges are generally at least PN2.5Ppa. Butt welding is used to reduce stress concentration. Butt welding flanges are mostly neck flanges, also called nipple flanges. Therefore, the installation cost, labor cost and auxiliary material cost of the butt welding flange are higher, because there is one more process.
