Generally, there is Plain PVC, CPVC, UPVC, PVC-U, PVC-M, PVC-O, and Lead Reinforced PVC; which is being phased out due to health concerns. PVC-O, -M, and -O deal with wall thickness. There are also different Pipe Schedules of PVC Pipe; (40, 80, etc.)
Polyvinyl chloride or uPVC (unplasticized polyvinyl chloride) pipes are not well suited for hot water lines and have been restricted from inside water supply line use in the USA for homes since 2006.
It has more improved properties than both PVC and UPVC. The main difference between UPVC and CPVC is that UPVC is made without adding plasticizers whereas CPVC is made by adding plasticizers and it is chlorinated as well.
cPVC profiles
uPVC is highly durable and it can withstand torrential rains and high winds. cPVC is less durable as compared to UPVC. While uPVC profiles majorly in the building industry. cPVC profiles are used for industrial liquid handling.Unplasticized polyvinyl chloride UPVC Pipes , also known as rigid PVC, Pipes & Fittings are used for all plumbing purposes in residential & commercial buildings. Ideally suited for looping at each floor level, outdoor installations & concealed pipelines for cold water distribution.

PPR is an acronym that stands for “point per reception.” It is as simple as it sounds: For every catch a player on your fantasy team accrues, you earn a point.
PPR pipe is a Pipe made of Polypropylene Random Copolymer (Polypropylene Random Copolymer type 3). The raw material used for this is Polypropylene Random Copolymer (PPR-C Type 3). The PPR pipes mainly designed for the distribution of hot and cold water.
Application of PPR Pipe Plant
PP-R pipes are used to build hot and cold water systems, including central heating systems. PP-R pipes are a part of building heating system, including floor, wall and radiant heating systems. PP-R pipes can be directly purified water drinking water supply systems.Product, Process and Resource +2variants. Technology, Product, Science. PPR. Product Process Resource.
PPR is slightly more resistant to chemicals. PPR - Presently PP-R pipes & fittings are most reliable in plumbing and water supply plants, due to their chemical features and fusion welding, which ensures the plumbing to have a perfect seal tight system. It can be used both as a cold water pipe or a hot water pipe.
Different wall thickness:
PPR and PVC pipe's main difference is the wall thickness(with the same diameter), PPR pipe is thick and PVC pipe is thin. The size is divided according to the outer diameter of the pipe, there are 20, 25, 32, 40, 50, 63, etc.In the case of PPR, the chlorine and chlorine dioxide used to disinfect drinking water corrodes the piping material. Over time, the degraded material erodes away and the pipe wall thins, weakening it and leading to leaks.

PVC is produced by polymerization of vinyl chloride monomer (VCM). The main polymerization methods include suspension, emulsion, and bulk (mass) methods. About 80% of production involves suspension polymerization. The PVC is separated off and dried to form a white powder also known as PVC resin (see flow diagram).

1.1 This standard covers requirements for plain as well as socket-ended pipes, including those for use with elastomeric sealing rings, for potable water supplies. 1.2 This standard does not cover unplasticized PVC pipes for use in suction and delivery lines of agricultural pumps,' which have been covered in IS 12231.
Diffen › Home Improvement. Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers. If no plasticizers are added, it is known as uPVC (unplasticized polyvinyl chloride), rigid PVC, or vinyl siding in the U.S.
