Pros and cons of propylene pipes

Welding propylene pipes.Necessary equipment

Benefits propylene pipes:

• they absolutely do not corrode;
• they are durable;
• not subject to accidents and leaks;
• have a perfectly smooth inner surface, which reduces friction during movement of coolant thereon.This makes it possible to reduce the diameter without loss of thermal efficiency.In addition, because of these same qualities, does not accumulate in the pipes scum, fatty plaque or other deposits.
• products have a thick enough wall.Although this factor can be attributed to the pluses and minuses.Pros - low thermal conductivity, due to which it is impossible to get burned by touching the pipe.Minus - a large volume of work, if you want to lay a pipe hidden longer have to indent the wall to accommodate the larger diameter.
• easy installation thanks to the large range of accessories to PP pipes.
• resistant to chemically aggressive environments;
• low price - the main advantage of PP products.

Lack propylene pipes - high coefficient of linear expansion, which leads to their sagging.To avoid this, the installation of heating systems using products with aluminum reinforcement on the inner diameter.

If you have to carry out heating system long enough wiring, it is necessary to learn how to produce propylene soldering pipes and installation of the entire system, and most importantly, what tools are needed for this.The standard set of tools for the installation of wiring includes:

1. welding machine to 1500W of power, which can be powered by 220 V.
2. Nozzles Teflon.
3. Soldering iron stand.
4. holder pipe.
5. Scissors.
6. Roulette.
7. template holes.
8. wrenches.
9. level.

Stages

welding process itself is not complicated and is in the following steps.

• Step One
  
  cut the required number of tubes perpendicular to the axis.If we are dealing with inside a reinforced tube, then you first need to clean the top layer, and then remove the shaver foil.
• Step Two
  
  thoroughly cleans the mating ends.
• Step Three
  
  Heat the welding machine up to 260o temperature.Once start flashing green light means you can start soldering.
• Step Four
  
  simultaneously warm up the welding machine and pipe and fitting.Once pipe and fitting warmed up, we insert it in the fitting and presses to the longitudinal axis.When the fused parts can not change their position.

time for which there is a complete soldering cycle depends on the size of the propylene tubes.The heating pipe and fitting should be done within the time that is recommended in the regulations.The pipe diameter of 16 mm and 20 mm it is necessary to heat 5 seconds, 25 mm - 7 seconds, 32 mm - 8 seconds, 40 mm - 12 seconds.If exceed regulatory heating time, melts and plastic parts can be deformed, and if the heating is insufficient, the solder will be weak and further leakage may occur.

How much is a welding polypropylene pipes

If you do not have the necessary equipment or simply do not have time to deal with the repair work, the master readily do the job for you, and the average price is listed below.
