Ductile Iron Welding Flanged Pipe

The flanged pipe is a pipe connected with flanges, the connection needs to be aligned with the two flange bolt holes, put the flange gasket in the middle of the flange, bolts go through the bolt holes, tighten the nut to tighten the two flanges with bolts, squeeze the gasket in the middle, through the deformation of the gasket to form a seal for the liquid or gas.The fixed flanges on the pipe ends can be casted on,threaded on or welded on,for loose flange,you can simply assemble it on.
