How Do I Flange a Pipe?
Flanges are the large, circular part at the end of a pipe that attaches it to another pipe or a valve. There are several holes in the flange which allow for bolts to hold the pieces together. If the pipe doesn't have a flange, you may have to attach one yourself. Does this Spark an idea?

Selection
-
To select the correct size flange to attach to your pipe, you need the diameter of the pipe you're attaching it to as well as the size of the flange to which this flange will eventually connect.
Preparation
-
Clean the end of the pipe that's being flanged, followed by sanding and polishing. The metal must smooth and debris-free so the weld holds the flange securely.
-
Attachment
-
Welding the flange on is the only way to keep it on the pipe and handle any type of pressure. A simple piping adhesive compound will not do the trick. It's likely you will experience catastrophic failure if you have a poor weld; unless you are skilled at welding, consider hiring a professional to do this.
