HDPE PIPE BUTT FUSION METHOD

 

HDPE pressure piping system use butt fusion to connect for big size, socket fusion for small size

 

Butt fusion is using welding machine to heat pipe at both ends ( the temperature is 210 + - 10℃)until the pipe end melted, it should adhesion the HDPE pipe end rapidly and keep a certain pressure, after cooling, all the procedures have been finished, the following table is the reference for the welding procedures.
