PPR
PIPING SYSTEM
What is PPR ?
VPL PPR pipes and fittings are manufactured using Polypropylene Random Copolymer (PP-RC), which is the most reliable polymer in the piping industry. The superior physical characteristics of PPR such as having a working temperature from – 20° upto 95°C, along with excellent chemical resistance, Providing a definite solution to oxidation and calcification; make VPL PPR Piping Systems ideal primarily for chemical transportation, in pharmaceutical companies and for other industrial use, as well as, hot & cold water plumbing systems in buildings and industrial Piping.
Due to the high level of strength and light weight, VPL PPR Piping System prove to be the most trusted piping system to be employed in industrial applications and water supply (hot and cold).
The physio-chemical features of Polypropylene Random Copolymer and the type of welding carried out – fusion welding – ensures that the piping system maintains a perfect seal even under the most difficult conditions, which makes it suitable to be used for various other systems like air distribution, radiator heating, etc. VPL PPR Piping System are physically superior, hygienically safe and non-carcinogenic.
The Pipes are manufactured as per IS 15801 and are available in PN 6, PN10, PN 16 & PN 20.
- The available range of pipes and fittings varies from 16 mm to 160mm.
- The pipes & fittings are available in 2 different colours:

Advantage of PPR pipes
- Weight: Light weight- Easy to handle, transport and install. Hence, saves labour cost.+ Corrosion Resistance: High Corrosion Resistance -No scaling; can withstand higher ‘pH’ values.
- Toxicity: Non Toxic – Safe for drinking No harmful effects on human beings & environment.
- Softening Temperature: High Vicat Softening Temperature – Ensures thermal stability for hot water applications.
- UV Resistance: High UV Resistance – The outer layer out of the three layer pipes, is UV resistant which makes them suitable for outdoor installations exposed to direct sunlight.
- Thermal Insulation: Prevents the heat from escaping from the hot water used for household/industrial purpose.
- Chemical Resistance: Non-reactive to most of the chemicals &industrial liquids.
- Strength: Stiffer & stronger than the standards Suitable for use in seismic areas.
- Jointing Process: Doesn’t require any use of solvent for The joints are welded together which results in a homogeneous plastic system that is leak proof.
- Noise Insulation: Minimum water hammer sound.
- Anti bacterial: Can be used underground because of anti- bacterial properties.
- Coefficient of Friction: Low pressure drops help reduce pumping cost.
- High Volume Resistivity: Poor conductor of No effect of stray currents.
- Linear Expansion: 75% less linear expansion than standard pipes.
Applications
- Piping systems for transportation of aggressive fluids in industries.
- Pharmaceuticals
- Compressed air supply system.
- Transportation of drinking water and liquid food.
- Indoor as well as outdoor hot & cold water piping systems.
- Solar water heating systems.
- Heating system inside buildings; including floor, wall and radiator heating.
Areas of Installation
- Residential and commercial buildings.
- Public places such as cinema halls, airports, railway Stations, bus stations, etc.
- Hospitals, schools & colleges and hotels.
- Swimming pools.
- Industries such as chemical plants, breweries, petroleum & gas plants, oil plants, mineral water plants, water treatment plants, etc.
- Solar water heating systems.
Advantages of PPR pipes
Property | Copper | Galvanized Iron | Vectus PPR |
Type of joint | Soldering | Threaded | Fusion Socket Welding. For transition joints. fittings with threaded metal inserts are also available |
Installation | Time consuming & requires skill | Tedious & time consuming | Easy to install, saves time & labour cost |
Corrosion Resistance | Non resistant | Not resistant | Free from corrosion |
Chemical Resistance | Poor | Not resistant | Excellent chemical resistance even at fairty high temperature |
Scale Formation | Common | Very common | No scaling |
Suitability in cold areas-sub-zero temperature | Not suitable pipe bursts | Not suitable pipe bursts | Most suitable due to typical elastic nature and good impact strength |
Insulation requirements | Essential | Essential | Not required |
Impact strength | Less | Excellent | High impact strength |
Life span under rated pressure & temperature | 20-30 years | 5-15 years | Can exceed 50 years |
Reaction to fire | Resistant but de-shape or punctures | Resistant | Melts like all other plastics but no generation of any toxic gases |
