Do I need to use the same heat fusion device for “PR” and “PPR” water pipes?
What is the difference between heat fusion and?It is possible to use the same hot melting machine.
The thermal fusion rate of PE ranges from 200 to 230, and the temperature of thermal fusion in PPR is between 260 and 280.
Four key points need to be considered when constructing hot melt PE pipes.
- Welding temperature as well as time, pressure, and the cleanliness of the surface. The temperature is determined based on the raw material’s grade PE100 is 215-235 degrees Celsius PE80 is 200-220 degrees Celsius. The welding machine and the pipe will determine the time and pressure. The welding surface should be free of dirt.
- welding seam excellent or bad judgment generally through the control of the program and its appearance test Flanging evenly symmetrical moderate height; smooth, without any bump marks, the bottom spot of weld higher than the pipe’s surface. The line Back bending test welding does not cause cracks.
- The 3. PPR pipe melt temperature can be between 260 and 280, which is the average temperature (room temperature) in an average of 20.
- Thermostatic heat fusion without changing the temperature.
- when in 5 in a cold climate (-5 lower than) and windy conditions for connection, you should take precautions or alter the connection process.
When the surrounding air temperature is lower than 5degrees, the time to heat is to be increased by 50%.
