The difference between the welding and butt welding of flange
Give you a plastic mark:Step 1: install the pipe, have you seen it?The second step: any of you saw a short knot down, but one must have a flange headThe third step: you have just saw the original welding back, and then the welding method is butt weldingThe weld flange is similar to the part you just welded back, except that the pipe is short and short, that is to say, there is a short short tube attached to the flange of the weld flange, and the short tube is welded to your pipe.Flange and pipe flange weld is also worn in the lap, is the pipe flange welding.The above is not a formal explanation, just to make you understand
I suggest that you see the welding standard or GB150, which is described in detail.Here I will simply say, flange welding mainly used for welding flange, butt welding mainly used for welding flange, flange welding flange and the difference is whether there is a neck flange; only a flange and pipe welding of the torus, when the welding angle is 90 degrees, called flat welding flange to flange; a flange neck, neck flange and pipe diameter, pipe and butt welding flange, the interface open 45 degree groove (there are other point of view, see the process and decide), the pipe and the flange neck at 180 DEG, welding directly in the groove, which is called butt welding.In short, the flat is --90 degrees, --180 degrees butt welding
