PSP steel plastic composite pipe transition, according to the head can directly melt with PPR
Within the specified changeover time, the transition joint shall be rapidly inserted into the pipe at the corresponding depth without rotating in the direction of the axis. A certain amount of pressure shall be maintained, the joint shall be pressed, cooled and fixed, and the rotation shall be strictly prohibited.
To achieve the specified heating time and sufficient heat absorption after melting, it is observed that a uniform melt overflow is produced, and the transition joint and the pipe fittings are removed from the die immediately;
Pipes and fittings that have been welded into the transition joint are heated at the same time into the hot melt to reach the specified depth;
The PP-R/PE welding machine (1200W, 260 degrees C) is selected, and the surface of the hot melt die, the transition joint and the pipe surface are cleaned, and the temperature is up to 260 degrees C (green indicator light);
