Homogeneous Joint using a heating process known as fusion jointing. It is a simple process and the results are leak proof tight joints and maintenance free.
Mark the socket depth on the pipe end.
Cut the pipe with a paper tool and deburr the pipe from inside to avoid vibration, noise and clogs from debris.
Mark the welding depth on the pipe end.
Insert the end of the pipe into the heating sleeve up to the marked welding depth and slide the fitting into the other side of the heading tool, up to the a stop.
Leave both pipe fitting on the heating tool until the heating time is elapsed.
Remove the pipe and fitting and push them immediately each other up to the mark indicating the welding depth.
Do not rotate the pipe and fitting relative to each other. Allow the join to cool fully before using.
