PPR according to Wikipedia is;
“Polypropylene (PP) also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, transvaginal mesh[1] and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
Polypropylene has a relatively slippery “low energy surface” that means that many common glues will not form adequate joints. Joining of polypropylene is often done using welding processes.”
So what is the advantage of using PPR material pipes?
Bin Dasmal Group held a study comparing about PPR and GI pipes, he’s is what they came into conclusion.
“According to the PPR suppliers, some of the advantages of a PPR pipe in contrast with a GI pipe are as follows:
1. PPR pipes are much more lightweight than GI pipes. Although GI pipes themselves are usually quite light, PPR pipes outperform the metal by a huge degree. Lightweight materials also help keep transportation and handling costs low.
2. PPR pipes also happen to have a very smooth internal surface, which is not something GI pipes can achieve. Smooth internal surfaces create less friction and less buildup.
3. PPR can achieve a higher level of flow than GI pipes, which requires less power and reduces the cost of electric power.
4. PPR pipes are more resistant to corrosion than GI pipes.
5. PPR pipes are leak proof compared to many GI pipes, which are threaded together and run the risk of eventually losing their galvanization.
6. No significant additional materials are required when installing PPR pipes, which lowers cost and raises ease of installation significantly.
Though certain circumstances and the presence of multiple variables might still lead you to select GI pipes over PPR ones, at a glance PPR pipes present a host of advantages over their metal counterparts.”
