About PPR Pipes


PPR pipes are made of polypropylene random copolymer (PPR-C) material and are suitable for hot and cold water applications, as well as heating systems. PPR pipes have a good resistance to chemical and environmental stressors, making them an ideal choice for plumbing and HVAC applications. PPR pipes are available in a variety of sizes and lengths, and can be connected using various methods, including welding, crimping, or screwing.

PPR pipe properties

low thermal conductivity

The thermal conductivity of PPR is very low, which means that the temperature cannot be easily conducted from the outside environment to the liquid in the pipe and vice versa. This factor reduces heat loss or gain during the transfer of hot or cold fluids, respectively, resulting in energy efficient systems and lower insulation costs for PPR piping.


Long life and durability

PPR piping systems can remain functional for over 50 years across a wide range of fluids and ambient operating temperatures. Additionally, PPR pipes exhibit excellent durability in both hot and cold water systems. First, it can withstand the temperature and pressure strains of a hot water system.

At the same time, unlike other common types of plastic pipes, PPR pipes are structurally able to withstand shock even in cold weather installations without any risk of cracking or breaking.

Main Uses of PPR Pipe Fittings

The most popular uses for Polypropylene (PPR) pipe fittings are in the transportation and handling of liquids.  These applications usually consist of pumping or transferring fluids between containers such as tanks, drums, pails, jugs, kegs, etc.

Pumps such as diaphragm pumps, peristaltic (rubber) tube pumps, and piston/plunger pumps are the types commonly used with polypropylene tubing to transport these fluid products. A few examples would be in dairy farms where the product is milk, in beverage industries VALVES PRODUCT,STRAINERS and MANIFOLDS & ACCESSORIES where salad dressings for salad bars are being kept cool.

Other uses of PPR Pipe Fittings include

Examples could be for compressed air in cylinders used by local shops like tire places or auto parts stores; water distribution systems where hot or cold potable water is used in homes; many types of farming; paper companies that use recycled water for paper making, cooling towers in large shopping malls or complexes where air conditioning is running throughout the building; aquariums that use pumps to circulate water through filters and aeration equipment.

They can handle hot high temperatures up to 160 degrees F without warping because PPR pipe fittings meet FDA requirements for contact with consumable/edible food products. This is also true for non-potable applications of draining hot water tanks and heating systems.






Efficient inner surface

The inner surface of the PPR pipe is very smooth and has a very low coefficient of friction compared to conventional types of pipes. This reduces pressure losses during fluid transfer and distribution, further improving the energy efficiency of PPR piping systems. Also, unlike metal pipes, PPR will not flake or scale, making it safer to use.


Chemical and Mechanical Durability

Compared to traditional plastic piping systems, PPR has a very high resistance to hard particle abrasion. This is especially important in well water or industrial applications where the transferred fluid may contain abrasive particles.

Furthermore, unlike traditional metal pipes, PPRs are inert to most electrolytes and chemicals over a wide temperature range. This electrolytic and chemical inertness makes PPR pipes safe to use in situations of high salinity (such as in swimming pool applications using seawater) and even highly corrosive chemicals (such as in industrial applications).


Eco-economic efficiency

Due to the light weight of PPR pipe, its transportation, handling and installation do not require a lot of energy consumption or manual labor. At the same time, they are easy to cut, connect and use, making them more economically sustainable.

Also, connecting the PPR pipes and fittings is done by heating only and does not require any additional chemicals or materials. All of these factors help PPR reduce environmental impact and cost of use.
