The Basic FAQ Guide of PPR vs PVC

Difference between PVC and PPR Plumbing Pipes Generally, all plumbing pipes are designed for different water applications and comply with the health effects standards. But, there are some major differences between the two types, we will try to answer questions that will help you choose the best fit for your renovation project.

PVC

PPr

 

 

Material

 

PVC is made of Polyvinyl Chloride. PVC belongs to the Thermoplastic Division of Plastic Materials. Being Thermoplastic, PVC soften when heated and harden when cooled.

PPr is made of Random Copolymer Polypropylene. PPr belongs to the Thermoplastic Division of Plastic Materials. Being Thermoplastic, PPr soften when heated and harden when cooled.

 

 

Joining Method

PVC Pipes and Fittings are joined by PVC Cement/Glue or Adhesives which have strong Chemical Odor due to high solvent to keep the glue in Liquid Form. Glue Joints can fail and the glue itself can be harmful to health.

PPr Pipes and Fittings are join by Fusion Welding, ensuring a homogeneous, all plastic system. PPr Piping System are safe and non-toxic. With proper welding, a homogeneous joint is assured and no chances of joint failure.

 

Material Density

Plasticized and unplasticized PVC have a material density of 1.2 and

1.37 gm/cc respectively. This makes the PVC products heavier

compared to PPr Products.

 

 

PPr have a material density of 0.90 gm/cc. This makes the PPr products lighter compare to PVC Products.

 

 

Stiffness

PVC Pipes and Fittings are more rigid compared to PPr. Due to this characteristics, PVC pipes and fittings are more sensitive to shock and have a high chances of breakage.

 

 

PPr Pipes and Fittings have a good balance of stiffness to toughness, with low tendency to stress cracking due to shock.

 

 

 

 

 

 

Field of Application


PVC is used in many industries such as building materials and packaging. Uses includes plumbing, sewage and drainage system, Drinking Water Distribution and service lines, irrigation System, Chemical Handling, Fumes, Exhaust and ventilation ducts, and other various industrial and recreation purposes.

 

PPr Piping System are ideal for hot and cold water distribution in buildings, industries, and heating and cooling Systems.

Most common PPR pipe applications include:

Hot and cold potable water piping in residential, industrial, and public installations. Industrial piping for transferring water, sanitary liquids, liquid food products, compressed air, and aggressive chemicals eg. highly acidic or alkaline solutions. Building central radiator heating water, usually in a circular loop piping

arrangement.
