Polypropylene pipes (PPR) are used for water supply and heating in residential buildings and apartments. These are fairly reliable materials with good performance and long service life. To connect these pipes, it is customary to use the soldering method. Heating makes the plastic elements softer and allows them to be sealed. However, not everyone knows what temperature is considered optimal for brazing PPR pipes. We decided to ask about this the employees of the "TRUBER" company, who specialize in the supply of sanitary ware. They provided us with all the information we needed. The range of polypropylene pipes for water supply can be viewed at the link of the online store https://truber.com.ua/g30951596-polipropilenovye-truby .
Temperature and time of PPR soldering for water supply
The efficiency of the process of joining polypropylene pipes for water supply and fittings into a single system depends on many factors, and the temperature and time of soldering play one of the key roles here. If you provide low heating, then diffusion will not occur. The weld will be too weak to handle the load. When overheated, the plastic begins to deform, a bead forms, which leads to a decrease in the hole diameter.
Experts advise to heat PPR pipes to 255-265 degrees. This is the optimum temperature at which a high-quality and reliable connection can be achieved. The soldering time depends on the diameter of the elements. For pipes 20 mm, it is 5 s for heating and 4 s for fixing. After welding, it takes 2 minutes for the joint to reach the desired strength.
How to weld polypropylene pipes correctly
To weld polypropylene pipes for water supply, you will need a special device. It has two slots into which the matching heating elements are inserted. The diameter of the welding sleeves is selected individually. Before starting work, be sure to prepare the workplace, since all actions will have to be performed very quickly. Please note that the soldering iron will be hot - think about how and where you will put it. It is best to work together.
Algorithm for soldering PPR pipes for water supply:
turn on the heating device in the network and wait until it reaches the required temperature - the LEDs will signal this;
insert prepared and cleaned plastic elements into the appropriate slots, wait until they heat up;
quickly remove the parts from the soldering iron and connect to each other, do not allow rotation, hold down for a few seconds;
allow time for the joint to cool naturally and gain the necessary strength, do not use a fan or cold water.
Do not forget to check the tightness of the welded areas before starting to fully use the water supply.
